Does the pulse repair mode have automatic shutting "OFF" display when pulse repair completed? Or they run forever ?
Thanks very much for that. Very interesting as I have the exact same one. Would it improve things to put the missing parts back? Also is motorcycle battery mode any good for maintenance? Apparently it has a 1.5 amp max, but would the early cutoff still rule maintenance out?
The best bet is to check the spec of your bike battery. Are your parts missing? - some are OK (ish). For a boost to get you going then this charger is OK. Personally I wouldn't use it without the missing parts. As well as severe noise emissions, the missing parts also affect reliability because the filter suppresses mains transient that destroy the switching FETs. . As is the case with many 'smart chargers' the accuracy of voltage sensing isn't really sufficient. It is not sealed so the charger should not be left switched on outside in a condensing environment such as tucked under a closed bonnet. Use for a boost but get something better for long-term battery support.
@@razenby Good advice, thanks mate.
Mine is absolutely the same externally, but it's dated 2020-12 and actually the input AC filter elements are present. For now it seems to work fine. But indicated voltage and current are slightly off as in the video. Wondering if I should opt for a C3 charger.
Your charger is OK for the occasional charge. They are susceptible to damp and mains transients but for a quick charge where you need to get back on the road this works OK. The 8A rating is much higher than the manufacturer's specification for most average sized VRLA car starting batteries. It won't do any harm if used occasionally as it might somewhat recondition light sulfated plates. If you leave it connected to 240V mains power then it is likely to blow in a few weeks. Antyhing stronger than a gnat fart will upset it.
Thank you for sharing. I was about to buy one but after seeing this I'll get a better quality branded unit.
You are welcome.
I have a vehicle which doesn't get used often at all and I was looking to get something that I could leave on all the time. I'd watched a few "reviews" which were positive so I placed an order with Amazon earlier. After watching this very informative video I've just cancelled the order. I might wait for your next video if you do mod it safe/legal, I'm handy enough with a soldering iron and enjoy little projects and maybe I'll reorder one in the future. Unless you have any recommendations for a smart charger/maintainer at ~5A for £50 or under?
Subbed. :thumbsup:
The Aldi AutoXs charger I reviewed last week (see video for Model number) is a good bet for lead acid support maintenance. It wont keep it fully topped up during very cold weather as it has no temperature compensation. However it will protect the battery and maintain the terminal voltage well away from the sulphation zone. They may still have some left at Aldi.
Thanks for the detailed technical review sir and the EMF issues.I own a variant of the charger( Foxsur) and would like to know is it safe to charge the battery while it's connected to car terminals? Would is effect the car ECU etc. due to design issues? Thanks.
You are welcome. There is a lot of RF noise so it should be OK to charge with the battery connected to the car circuits.
@@razenby Thanks, so just to make it more clear, having RF noise has no effect on car circuits? Thanks very much.
@@christopherschokman1604 You are welcome
Nice video, I have been using this charger for about 3 years out of my service vehicle to charge machines including 24v machines. It works very well for me, except the auto voltage sensing cant be manually set to 12 or 24, so Im going to upgrade to a telwin touring type.
It also runs my 12v fridge in my shed hooked in parellel to a jumpstarter. I leave it there for months at a time. 👍
Mine is still working too. They come to the UK with various levels of filtering and protection installed. Some have all others have none. I wouldn't use mine to do battery maintenance as the termination f charge voltage isn't very accurate. But agreed if you have a parasitic load then anything is better than letting the battery to get to a very low state of charge.
Having watched this video a few days back, I bought the latest version of this, It's 12v/10amp - 24v/5amp, model RJ-C121001A. The front panel is almost identical, but it has an additional mode between AGM/GEL and Motorcycle, it says WET under a small picture of a battery(?!). I've just charged a 90Ah lead acid battery that measured 12.3v when free standing on the STD mode. It certainly faster than the 6amp Maypole smart charger it's replaced, but I'm not inclined to leave it connected after it hits Full because I'm not clear in my mind about how it maintains the battery fully charged until I want to use it. Also, I was pleased to see my neighbour who has a pacemaker walking about this morning, clearly he was spared death by RFI :-D
Hi Mark, I haven't seen that model. Presumably they beefed it up squeezing more power out. Hopefully they haven't screwed what reliability it has. Your battery manufacturer would recommend a ~4 amp (ish) is charge current. Bigger currents save time but if charging a near flat battery with a low state of charge , pumping in too many amps during the early stages of the bulk charge phase is not ideal. For a healthy Lead-Acid battery ad acid self discharge is very slow. If you have no parasitic drain (battery disconnected or a switched load - not a vehicle with alarm and central locking etc.) then it is far better to periodically charge the battery say every 3 of 4 months disconnecting the battery between charges. Plus if you leave your charger powered up then a mains transient will come along and destroy it. They don't have adequate protection because they simply aren't designed for UK mains voltages where it can often get as high as 260V RMS instead of the piddly European 220-230V...
@@razenby I also have one like this, 7 Stage 10Amp etc, will love to see a review on the latest model if you are able to please?
I bought Anhtczyx with the date 08.2020 and it has filters like in the new Foxsur. I think it's exactly the same factory
Interesting.
Makes me appreciate the CTEK charger a lot more
Indeed.
ctek do not have led display, dummy led lites
What does this LCD display tell you (that is valuable info) that the CTEK doesn't? And alternatively the CTEK always indicates which mode of 8 it is running in. Basic LEDs last forever. LCDs don't. @@ObservableUniverse888
@@kellyanderson7115 Best of the two worlds would be Ctek with Volt and Ampmeter- voltage and amp meter would show how discharged battery really was. I added cheap chinese digital panel amp and voltmeter(it was cheaper than analog ampmeter:) to old no electronics other than diodes battery charger- it's actually very helpful to see what charge/battery voltage is.
Just got one of these to try repair a old 12v 50amp battery.
Im trying the old clean the battery out with baking soda and refill with Epson salt water.
Currently on repair mode, did you ever find out of repair mode even works? My unit states 102021 on the back.
The repair mode pulses current but as to whether it works or not is debatable. It may help an ailing battery but I have no evidence that it actually does much if anything to restore a badly sulphated battery. Prevention is far batter than any cure.
From the comments posted it seems that it really works well as a charger but you seem to have pot luck with units having the filters or not. I have ordered one of these and waiting for delivery. If i am unlucky and get one of the units with missing bits maybe someone could post the components list for the missing capacitor and filter choke. Thanks, great test and video.
It is a brutal get the power in - I am in hurry charger. 8A is too high for most batteries - have a look at the manufacturers specifications of your battery. Pumping 8A too ealy in the charge cycle will erode the battery plates. The components are listed in the description on this video that covers the modification. See th-cam.com/video/wZNhEB8_PCM/w-d-xo.html
Had purchased this then found the video. Mine is dated 2021-03 - missing parts weren't missing on mine. Hopefully your video and resulting complaints got them to throw in the extra few cents!
I believe it is the importer that is ignoring the CE requirements. It should not bear the CE mark!!
No cap across the transformer either and just to put the icing on the cake, the mains input is wired back to front, I wonder if that's causing even more EMC.
Could be. I will doctor it as I don't want to use it like this. It also interrupted next door's internet access to their workroom in the loft (It is connected by one of those TP link mains links to the ADSL modem). They just came round to see if I could help them out as they are working from home up there at the moment. To my shame I didn't tell them that it was playing up all morning because I was using the Battery charger! I thought that they would be on a different phase of the mains but they aren't.
Please also test the KONNWEI KW510 charger.
I don't have one to test- sorry.
I just bought one of these chargers from ebay. After getting it out of the box I noticed it had something rattling inside the case. Before powering it on I opened the case up to see what was loose inside.
Turns out there was some bits of plastic loose in there and after looking at the board inside I couldn't see anything broken in there.
First thing I looked at was if it had the suppression chokes on the supply and it does. The wiring they use for the supply in and DC out are as small as you can get.
Just as you said in the video they didn't bother to crimp the croc clips on properly.
So it will be interesting to see how long this unit lasts.
Interesting. Good luck with it.
Would this be good to use as a battery desulfator? I've got boat batteries and some batteries in equipment that can sit for years sometimes, and I'd like to try and bring them back, if possible.
Hello, good question. For a 12V battery that has been allowed to languish with its terminal voltage of less than 11.8 is probably a gonner. Some good can be done on larger supply and stationary batteries but for car starting batteries no. For slightly ailing batteries then desuplhation or repair may help. This charger has a reasonable repair mode and uses the same pulsing Repair/recond scheme scheme as the NOCO Genius range. Check the open voltage terminal voltage on your boat batteries and see what state they are in at the moment. I would not recommend this charger to be used for a resuscitation attempt as it piles straight in there very early with as much current as possible. This will damage the remaining active areas of the plates before any suplhate is removed. If your terminal voltage has dropped then don't do an 8A charge straight away. If you use this then try the repair mode to get the voltage one the pates up to a point where you can charge.( ~10.4 to 11V).
@@razenby Thank you for your response. I have n old Battery Minder branded charger that does a desulfate but it only charges at .75 amps. I've been using it for years connected to my tractor battery because it sits for years at a time. This seems to work very well at maintaining the battery. The current battery in the tractor us 6 years old and it's probably only been run for 3 to 5 hours in that time. But it starts up every time when I need to use it. I wonder if this might be a better choice in trying to desulfate my existing boat batteries..
I really only wanted this unit to use to desulfate (repair), not to use as a charger. If it's only use for repair, and if I went with their 5amp charger, would that work better than the one you tested?
Right now, I've got the old 2/10/start battery charger I've had for decades, the battery minder and a couple of 1amp Mroinge chargers I use to keep batteries charged... Problem is some things are stored in places without power... so I really need something for desultification, so when something is pulled out of storage, I can try and save the battery before recharging.
BTW, might a different type of battery be better for my needs?
Thank you!
Can someone tell me which values have the missing parts and what is to replace. I have only wire jumpers on some place like this in video. My sample missed the parts like the sample in the video.

Hi,
Does it charge dead car battery?
The car starts up with a jump starter but when I turn it off and try the ignition back on it doesn't start amd I have to jump start the battery again.
I think the battery needs to be fully charged so will this work?
Sound like your battery has failed. Check the car is charging too.
Excellent video!
Thank you! Cheers!
I wish I could find a schematic for this. Mine worked great for a few weeks but I attempted to revive a 12v boat battery that was apparently beyond repair and it smoked that last big transistor right by where the regulated 12V leaves the circuit out to the battery clamps. It went out like a fuse and appears none of the passive components immediately surrounding it were affected so I just need a spec on that transistor so I can try replacing it.
Is it the transistor mounted on the vertical heatskink by the power output? If you didn't find it let me know and I will take mine apart and have a look for you.
@@razenby Yes, the one right up against the BAT(-) output. Thanks, I really appreciate the reply!

Had terrible EMC issues on my Alinco DX-70 HF Transceiver yesterday ! Unable to hear any transmissions over the whole HF frequency range
Traced it down to my Foxsur Battery Charger which I was using at the time Pulse charging my car battery.
It was outside in the garage, well seperated from my radio but still plugged into the same mains circuit.
Turning off the charger completely resovled the issue !!!!
It looks exactly the same as this one apart from a yellow colouring instead of red.

They literally couldn't have done a worse job if they tried. All for the sake of saving a few cents...You can rob almost any old power supply for the bits you need.
Whey I plugged it in out of the box, the battery icon just flashes. What does that mean? Do I need to charge it up before using it?
I guess you need to connect to a lead acid battery with a terminal voltage above 7.5V
Hi, thanks for sharing.
Is it safe to use?
I have fast charger which many do not recommend.
Thanks
It does not comply with any international standards. It will interfere with the safe operation of any susceptible equipment.
@@razenby Thanks, i just ordered ctek mxs 3.8
good afternoon,what mode do i select
to charge a 12v leisure battery up on a system-j50 please.
Is it an AGM or normal wet lead acid battery?
So, can i use for charging my agm/gel batteries?
Fine for charging them but I wouldn't leave it connected to valuable batteries for maintenance - the voltage sensing isn't sufficiently accurate.
I found this video while searching this product to find out more about the difference between normal charge mode and pulse repair mode. I am not technically minded so don't understand anything about what is said here. In the cold snap I've had to charge my car battery s couple of times, just get 5 or 6 hours in so it'll start the next day when I've needed it. Now I'm confused and don't know if it's safe or any good! Any recommendations for something safe and reliable? I thought I *had* bought something safe and reliable compared to the very slow 1950s charger I borrowed from my uncle in the past!
Hi Andy, if you need to charge your battery every day then either you have a parasitic load on it when the vehicle is parked but it is much more likely that you have a duff battery there. investing in any kind of charger is a false economy. get a new battery.
@@razenby Sorry, post probably not clear. I go weeks at a time without driving, and when I do during winter, it's usually short journeys with heating up and lights on. Pretty sure it's the lack of use for long stretches combined with winter temps and only doing short trips with everything switched on that's the issue. I don't charge my battery every day. Anyway, my concern still stands regarding this charger, just wondered if it's safe and effective or not.
Hey i m trying to charge my motorcycle battery, battery says AGM on it. Should i choose AGM mode or motorcycle mode?
Assuming it is 12V .I would first charge on Motorcycle mode. When the first charge is completed then switch to AGM mode to do the final float/absorbtion charge. Reason: AGM batteries need a higher termination voltage but if you hit it with car AGM first the bulk charge current will be too high for a motorcycle battery. The final stages of AGM charge are low current. Remember to like and subscribe.

III be wait thanks.
What brand of battery charger do you recommend to be left on all the time?
If you just need battery maintenance then out of the one I have used the NOCO fares the best. I have three vehicles that I drive occasionally and each in maintained by a NOCO Genius 2 - 2 amp charger. They replaced CTEK MXS5.0 that repeatedly failed because they do not tolerate the mains supply. The three NOCO chargers have been running for over 9 years of 24/7 battery support without any charger failure. If you dont look after your batterries and want to squeeze an extra 6 months out of an ailing battery then the CTEK is the best tool but don't leave it connected to the power or subject to operation where the dew point can be crossed. i.e. With the CTEK do the task then unplug ans store in a dry place.
Hello where is any really difference between different modes in this charger. Car batteries . AGM. ect ?
They all produce electricity and require charging. But, some chargers are inaccurate and some are overpriced. others are seriously unreliable and different battery chemistry required a different charge voltages, currents and profiles.
great vid.. thanks for sharing.. i really like this machine! Im not sure but your voltage reading issue may be that its displaying the voltage used for charing,, rather than batter voltage.. normally it shows battery voltage when unplugged from AC. im not 100% but i think thats whats happening .. perhaps it shifts the voltage up as the battery charges..
also mine charges to 14.9V to full.. so im not sure why theres a diffference. im charging 150ah tubelar lead acid battery
Thanks. The voltage is the voltage at the terminals versus what the charger displays. Probably due to the cables voltage drop. If the voltage measured across the actual battery terminals is 14.9 Volts then that way too high for a lead acid battery. It will cause erosion of led from the plates.
@@razenby thanks ! good to know. this is a great machine.. mainly for pulsing .. i have revivded a really dead battery with gravity off the bottom of the scale back into the green zone..
@@AlexEarthshipLeeor Good to know. I have had no luck with bad batterries.
@@razenbyThats because your batteries were completely dead 😂😂 even more expensive chargers won't do a thing
Instructions say the pulse should run for 18hrs. Not sure if it cuts off by itself when done.
Yes, maybe it if it last for 18 hours with the power FET exploding, the software may cut-off but I doubt it. You can do repair for months and it likely won't do any good... Smoke and mirrors.
@@razenby ...Mine works just fine on Repair Mod. Shut off perfect. I checked everything ...Battery charged up fine.
but I Didn't Find any Magic Smoke and I Didn't see Any Mirrors!.... However my Charger IS yellow.... Not Red.
Can I use the motorcycle mode to trickle charge a large car battery through winter?
Not necessary, the smart charger cuts the charge when the battery is fully charged and then cuts back in with charge if the terminal voltage drops to low. If the battery is connected to the vehicle then the vehicle may exert a parasitic drain to power stuff like alarms. A goo full charged battery will happily sit for six months without damage. In some situations a maintenance charger might do more harm than good. In addition charging/maintaining whilst the battery is connected to the vehicle electrical system may confuse some smart chargers into maintaining the charge voltage too high for too long. So disconnect the battery if you can. The only thing with this charger in the video is that after six months when you go back it is unlikely to still be working. A couple of mains transients fries the power supply as there is virtually no built in protection.
Hello, thanks for this video. May you recommend me a charger that is safe. Im not interested in fast charging. So Im not looking for hig amperage. 4 amps is ok for me. I have seen NOCO, Schumacher, Optima, Energizer but according to Amazon reviews they all overcharge batteries and make them boil and fail to detect 14.8 volts peak voltage (for flooded batts). Im interested in good quality that means SAFE charging. Thanks a lot!!
I don't believe the reviews on Amazon about boiling or overcharging. Whenever you dig deeper they are always wrong. A little knowledge is a very bad thing. I have many chargers both expensive and cheap including Bosch, Optimate, NOCO, CTEK etc. On My V8 jaguar I use a NOCO Genius II to support the battery. Why ? because the CTEKS would blow up after a few months, I had two under warranty and they blew up, The NOCO genius 2 has been on duty supporting the battery for over 2 years 24/7. I say to everyone if you use your car for short journeys then you need to do a periodical float / absorption charge. If you VRLA starter battery is failing then there are no magic bullets so just replace it else it will let you down.
@@razenby Thanks very much. Very informative video and your comments as well. I have this ZYX-J30 dated in 2021 maybe it has all the missinfgparts you show, will see. To this date it has worked fine but I want something better quality. Im deciding between Optima or Energizer (both 4 amps). What you think Optima vs Energizer? (The thing I don't like much about NOCO is they don't display voltage nor amperage but will reconsider if necessary) Thanks a lot!!
I haven't tested either of those models so I cant say.
@@razenby Thanks!
I found one these chargers had to replace both cords plug and +/- i live here in America why is this charger illegal?
In both the UK and the US there are strict mandatory limits specified for safety and emissions compliance. The emissions is about the equipment not interfering with other devices and services. This product does not comply - not even close.
mine does not enter summer mode even if temperature is over 30C. How do i enable summer mode?
Sounds like the themistor cct is faulty.. It isn't an issue if you just want to top up your battery charge. It might be a problem for battery maintenance.
Thks & I order one off amazon just before I watched your good video;
??Could you get another one off amazon ; update your good video ; & add it to the playlist??
If it still don't have proper filtering, pls list the necessary components & how to fix the damned thing.
I think the ones on Amazon are slightly different. Do you have a link to the type you are talking about?
I havw this charger for a couple of months and it seems it has quit on me. It turns off right away even when battery is drained meaning its intelligence is gone! Can this be salvaged still?
Brad, have you tried it on a good battery? The one here dies when short-circuit the battery leads. It cant handle the current and the microprocessor browns out. They are so cheap that sadly they aren't worth fixing. If it is faulty then It is probably just a 20p component that has blown.
@@razenby Thanks for the reply. It works on a good battery esp a car battery. I noticed it doesn't work wel on motorcycle batteries. Even if bike batt is partially drained, it refuses to charge and stays off!
@@brad1878 Battery needs to meet minimum voltage requirements. Plug the battery to a "dumb" charger and after few some time to smart charger and it should charger it.

What I need to know is will it bugger my Battery if i use it every other month?
Should be OK for a straight top-up charge,
Yes
They work perfectly fine for what you pay for it. Revived a couple of my batteries including the land rovers massive DIN battery.
Still a lot better than those awful things car dealers use on the forecourts
True.
Great video, that's why it kill many prius 12V battery..
Thanks. It is OK as a get going quickly charger but does not really have any finesse or reliability engineered into it.
Yes, the AGM battery needs lower amp when it is almost full. Many people don't realize that'd at 0C full battery voltage is O.4 lower than at 25C. Many thought they need to charge the battery. My Auris hybrid at 0C is about 12.4V, its actually almost full all the time. It never have problem starting the car since 6 years ago.
@@razenby Do you ever test very popular BOSCH C3 charger? it is relatively cheap about 35€ and claimed to have chip-controller.
@@rondhole I have seen that one. I have a couple on the shelf awaiting testing but not a Bosch. I will add the Bosch to the list. The problem at the moment is time due to design contracts.
I believe this charger is much worse than Aldi. Some people reported the voltage is wrong and sometime as high as 15V and boil the battery.
Can you use this to trickle charge a car battery?
Yes. Short term. (A week). However I wouldn't leave it connected for long term battery maintenance because:
A: The voltage measurement during final stages of charge are not accurate
B. There is no temperature compensation.
C. When you go back to it will likely be blown up due to a mains transient due to the simplicity of the Switch Mode Supply. It just isn't that protected against Hi Majesties main supply.
Thanks! I appreciate the detailed answer
What would you recommend for a trickle charge on a car battery (going away for some time but want to keep the gps tracker alive while away)
Can use it to charge a 120amp batt?
No problem. This charger is better suited to higher higher aH capacity as in their specifications the manufacturers of small (~70aH) VRLA Auto staring batteries recommend 3A to 4A charging currents,.

C’est un très bon chargeur cela fait 2 ans que je l’utilise parfait
Peut-être que cela fonctionne mieux sur votre tension d'alimentation secteur française inférieure. Ici, ça va exploser si vous le laissez connecté à l'alimentation pendant un certain temps. Il y en a autant en décharge qu'en usage.
10:56 is not the error, but rather a voltage drop through the wires (due to the current flow). More current, more voltage drop. I assume that charger's microprocessor measures voltage on the charger's output, not on the alligator clips. Also, absolute maximum should be 14.4 volts, not 15 volts, never!
EDIT: Crude or minimalistic car battery charger contains only a transformer and one diode as a rectifier. That's what is called minimalistic, and it was working flawlessly many years prior modern electronic chargers.
I The voltages are monitored at the battery crocodile clips and the error is steady at just a couple of hundred milliamps of current in the charge cables. i.e low current=low voltage drop.
1. The charger micrcontroller knows the a voltage and current values therefore it could easily calculate a fairly accurate offset to the displayed value in order to compensate for cable resistance.
2. The accuracy of the A to D converter is limited by resolution, offset accuracy and the tolerances of components in the signal conditioning components. The theoretical accuracy matches the performance pretty well. See the calculations are in one of the NOCO vids.
Just checked mine and guess what ... no chokes and caps . Ordered the bits and will be doing the necessary surgery when they arrive to try and mitigate the EMC . Might put a ferrite suppressor on the cable just for good measure too . It's a hell of a desulphator though so bit loathed to bin it - It's rescued another battery this week. Wonder if all that noise is helping shake loose the sulphates.. LOL ! Not worth upsetting the neighbours though !!!
Did you buy in the UK? It is a real signal jammer. It blanked out the TPLink mains wifii link to our garage too. On the good side It does has the strongest desulphating pulses that I have tested. I noticed that the DC voltage sensing is more accurate with the filter comps fitted.
@@razenby Bought on Ebay . Shipped from UK (stock held in UK) but seller from China. All jokes aside .. this stuff really should not be getting into the EEC. Think it might have knocked the neighbours CCTV out because he was out fiddling with the cam this morning. Not going to use now until I put the choke ,caps, and varistor in.

That was good buy. Dont let it get damp and don't leave it connected to your battery for long periods. The termination voltage is not accurate. Good charger to get you going if you have left the lights on.
the .3 volt difference is caused by the resistance in the wires the charger is reading the Voltage from the circuit inside , your DVM is reading the voltage at the end of the Charging wires Which has resistance . the longer the wire the higher the resistance . One thing i Do is replace the China Made Electrolytic Capacitors in the charger with Good High Quality Low Impedance Capacitors Like Nichicon UHE
You overlooked the indicated voltage is is wrong at termination when about only 70mA charge current is flowing. If you are correct then the calculated resistance of the leads must turns be over 4 ohms. Confusing isn't it?? The charger knows the resistance of the leads and it knows the current flowing so can easily calculate the offset and compensate the display and transition / cut-off voltages. The real issue is the accuracy (resolution) of the cheap Micro's Analogue to digital converter and the tolerance of the divider chain resistors that sense the voltage.. The bit error and best theoretical accuracy is calculated in another video in this channel.
How much price that car battery charger
About GBP £20 to £25. There seem to be 3 variants with various states of CE filtering on the market.
13:26 Since when is a fully charged battery more than the industry standard float point of 13.6 volts ???????
let me see, in your world, since you misunderstood the 12V wet lead acid charging requirements. RTFM.
@@razenby 13:23 No it should not be at 15 volts when it go's to float ! 15+ volts when fast charging a depleted battery yes but as it tops itself out the voltage can be pulled back to insure the battery doesn't boil and then it can monitor amperage drop in the 13.7 range and then go into float. you should RTFM too ! LOL
@@luckyPiston some chargers like Schumacher and Optima take batteries up to 14.9 volts as terminal voltage. Once14.9 volts have been reached, it drops to 13.4 and trickle charge. Do you think Schumacher and Optima are doing it the wrong way taking standard flooded batteries up to 14.9?
@@carlosw1687 I wouldnt mind knowing why they do that , do share !
I just got one off Amazon today I popped it open and it’s got the stuff yours is missing
Good news. There is obviously a mixed bag out there,,,
Can you please post a link to the one you purchased?
@@richardlouie2922 I’ve been running the guts outta this thing and it’s awesome ,,,,,, I ran repair mode on a 2012 John Deere lawn tractor battery and the 10 year old battery outta my truck that wasn’t holding a charge and it actually seems to have fixed it ,,,time will tell but they are running great now ... I didn’t even know this was an option , gonna buy a second one for sure .
@@JonnyMudMower Link please? There are dozens of these chargers out there so knowing which one that you purchased would narrow things down. BTW> I saw a recent TH-cam video of a partial teardown of this charger and found the same thing you did - the previously missing bits are now there.
@@richardlouie2922 I posted the link but someone deleted it or it didn’t post I’ll try this ,,,,,, www.amazon.ca/dp/B083FG2742/ref=cm_sw_em_r_mt_dp_98SRWZ59R8FH46QSZ0VX?_encoding=UTF8&psc=1
Merci de votre réponse bonne journée
You are welcome! You too.
Hi which ones would you recommend for about £20 thanks. For a 12v (AGM) Toyota Prius battery. Had to jump start it last year, and this year again last 2 days. New battery cost is £124.00. thanks
If it is the small lead acid battery you are referring to then I have tried rejuvenating one of this and had no joy whatsoever. It is a ridiculous price for such a small battery. AKA Rip-Off I suppose the obvious thing to do is to check that the charging system is working properly and that there is on parasitic draw from the battery when parked.
mine is with ac filter but the charger is without brand name.
Interesting
How do you know if it has an AC filter?
i can not wait till you find a good battery charger
Me too
If they put emr filter and water slpash proof, dust proof, price will be doubled, and it will go no near to my bedroom ...and do the job...leave the extreme demand to those who is willing to pay 10 times...good choice..
Thanks for watching. This unit is a good basic unit for short charging periods in very dry environments.
@@razenby 85%of use，cut out red tapes to cater them with unbeatable price. Missiaya.good on them. They are not for dummies but one has basics .,
@@ObservableUniverse888 Red tapes are rules made for a good reason. . This is not a very reliable design unit so only Ok for occasional use else it will be scrap within a couple of years,
C tek for me all day long !, got one for my m3 and one for my Rv , you get what you pay for peeps!!
Get what you pay for?? - not with CTEK - it is an expensive cheap design - the 5A ones have serious reliability issues .. Keep it dry above the dew point.
you get what you pay for and in this case it actually works.. so is a cheap product that works, probably wont last long but again is cheap.
To cheap. Wouldn't you raather pay an extra dollar and have something that will last... ? Buy cheap, buy twice, 3 times , 4 times.... The only thing that suffers is the planet.
Don't use if you have a pace maker. Lol
Not sure how sensitive they are to EM these days but 20 years ago this could give you a wobble if you had a pacemaker!!
15 volts is too high! 14.2 to 14.4 is correct for a fully charged lead acid battery. Thank you for the informative video!
These chargers don't have very accurate voltage measurement. The accuracy (tolerance) of the network of components is 1% per part and the A to D is only accurate as the micros internal voltage measurement. Add to that potential shifts on the 0V rail and switching noise. They are all over the place. For a quick charge then it isn't a problem as there is a school of thought ( as yet unproven) that a slight overcharge for a brief period helps keep the plates clean. - It will etch the +vE electrode very slightly but is thought to help to reduce build up of sulfate on the electrodes.
Hi good to see you back I did send you a message before. Please could i get a contact email or other i have a Bose amp i need some help with regards Mike

I bought one from local store and I used it to charge my BMW E60 AGM battery where it was reading a capacity of 40% charge and I did charge it 100% after about 3 hr and a half.
I say this product is pretty good however its stating Foxsur battery charger instead.
Hi Talat. I agree it is a good get you doing charger. However most maintenance free battery manufacturers state a recommended charging current of around 3 Amps. (40 to 60 Ah capacity). Over-current will cause erosion of the plates. It is a blunt tool that is good when you are in a hurry but don't leave it on support charge.
It's not so smart. Mine didn't stop charging once battery was full.
It should stop charging around 14.4V DC on the terminals. How did you know that the battery was full?
@@razenby Well after fed up waiting for it to stop for over 24hours I disconnected it and the checked the battery voltage from the car dash reading. It read 13.4 V indicating an overcharge If i'm correct?
@@ka5269 Well??? Is he or is he not correct?
it’s a good charger
Yes, it will stuff power into your battery to get you going but don't use it as a maintenance charger and do't leave it connected to the mains for long periods - it wont survive.
@@razenby Whats long periods?
i am in AWWWW !!!! that much interferance??????
Truly the worse example ever. Not even a nod to safety or the regulations.
lol
Wow. Haven't seen anything this bad before. FCC logo on box. Yeah. Sure. What's the FCC ID haha. These products circumvent regulations pretty easily. Even if the product becomes banned for import, there are lots of alternate brands and labels that these kinds of things can be sold as. That mains fuse is the smallest fuse I've ever seen. Almost no glass.. barely meets minimum creepage distance. I'm sure it was some fraction of a cent cheaper. These products rely on volume to make a profit.. taking out all input filtering would raise margins substantially. Did you purchase this in a retail outlet, or was it ordered online? Penalties when it comes to retail sales of products with falsified compliance can be severe.
It is really bad. I bought it from a UK importer on Amazon. Shipped from the UK. There is probably about $1.20 US worth of parts missing at Chinese internal market prices. I filed a report with the UK trading standards agency this morning. Anything seems to be acceptable in pursuit of profit.
Missing out $1.20 of parts is not acceptable. Penny pinching bstards. Just sell it for 1.20 more.

Ive just had a unit delivered and scanned the user guide as I note your comment that you couldn't find yours.

Your video was very helpful to me in troubleshooting a problem with my unit which I received yesterday and was able to repair.
Glad you found it useful.
So can't jump start a car with it
No, but you could transmit on Long wave band..
What if this was connected to a power conditioner?
If there are filter if the conditioner then it would help. The mains lead would still radiate badly but it would not enter the mains supply wiring..
Bloody hell! I hope the Russians don't see this or they'll be using them to jam communications in Ukraine. Just bought one of these as well. I noticed in the comments on Amazon before I bought it that someone complained that his neighbours wi-fi stopped working when he was using it, but it still had 4.5 stars out of 5 in the reviews.
LOL. It is quite an achievement to jam WIFI. To get ~2GHz noise from 50 Khz switch mode an achievement... It ranks up there the baddest crap I have seen. When the Radio Communication Agency was around the importer would be in court. With no enforcement of basic safety rules , the UK is just a dumping ground for fallaciously marked CE marked products .
I am using the same charger and I have no idea what you guys are on about, my wifi works, my TV works (and charger is plugged into same socket) whilst I am typing it's charging my W164 ML AGM battery fine. And once full, I will use repair mode and pulse charge. Did my motorbike battery las night, same method, charge to 100 and then put into repair mode until it shut itself off. Jobs a good un.
Got the same, over charges agm, worked 3 times then now only screams high pitch continuous. Does nothing.
PIECE of shit don't buy.
Not everyone likes a screamer!! Buy better buy once but don't buy CTEK!!
This crap is crap. some are good I bought 2. the other one is not working properly. I guess this thing is not a good buy since there are severely high chance to get a broken one.. not worth.
Good call. Yes, too cheap. If they had just spent another couple of dollars on design and components then it would be a good thing. The whole world suffers as long as people keep consuming crap and throwing it away and making more crap for the land-fill. Thanks for watching.
@@razenby Could have been worse... the whole thing could have been sealed (ie the CTEKs or the NOCOs) so that these modifications can't be done easily. At least with this type of design, modifications can be done.
How do you know if you got a broken one?
China has a quality good one.Outside the marketThe cheap people.They need..In China. chinese，the use good quality item。
A poorly designed and cheaply made product that ends up in land-fill at the dump after a few years use in no way can be described as good quality.
Say what?
@@razenby Yep...their car EV Batteries will end up in landfills too. Its why ICE ain't going nowhere. The EV BS will be stopped in the US.
