Hi Steve, I've just got the Uniross version and your very helpful video has saved me from having to read the tiny little written manual, thank you very much.
Glenda Gobstoppa
lOL, I have same model, had it for a few years, but wanted to understand it better and here we both are :)
I've got this charger and needed to refresh my memory for use of charger after a year in the cupboard so thanks for the refresh. 👍
Nice one, glad it helped
Brilliant video. Most informative video I've seen. Will definitely subscribe. Thank you.
Thanks David, I hope you enjoy the videos. Please share
I have the Uniross version of this charger. I use the USB outlet to power a
small (80mm) computer fan to keep the batteries and charger cool throughout the charging process. At 5v this 12v fan runs at a gentle rate and with only a slight amount of noise. I have a finger guard on each side of the fan.
Good review, thanks.
I would only say that the charge rate you mention is 700 milliamps (ma) and the accumulated charge is in milliamp-hours (mah)
Great video.
I’ve been charging a 2800 at 200 since I got it.
Now I know why it’s taking so long!
Thanks for an in depth, clear and concise explinantion.
Cool thanks for sharing was wondering about the modes, and current buttons.
happy to help.
Glad i found your video because I got one of these to charge the batteries for my camping gear like head torches etc and got confused with the printed instructions. Now i know whats what so cheers for that :)
Peace
Glad I could help
Very easy to understand great video
Awesome, glad you liked it
This charger is just a cheap copy of the excellent Technoline BL700 which I've used many years. I bought one of these Yoshiko models but found it to be annoyingly unreliable over tine and find the readings it gives are erratic and far from accurate compared to the BL700 when measured on test equipment we use at work. There are quite a few TH-cam reviews of the YC4000 which highlight some of its problems .
If you do fancy this charger then forget the Yoshiko YC4000 which is an utter rip off when compared to the same model, the 7dayshop intelligent charger and the Uniross Ultimate which are both available for just under £20 on eBay and Amazon are are EXACTLY the same as the Yoshiko YC4000 apart from the badge.
If you really want to do it properly though then go for the Technoline BL700N which is what these other models are cheap copies of, the Technology BL700N is a legend and quite simply the best of the best.
Never had a problem with mine and there are hundreds of clones of all sorts out there in the market place for electronics.. Thanks for your comment though and they may help others when choosing a re-charger
Well I’ve just purchased the 4000 for £25 on Amazon U.K. (Prime). The BL700N is going for £35.
no! this is the best charger Maha MH-C9000 - after few of my batteries that reduced to only half of its capacity - this was the only charger got it to its full capacity - after a few recycle!
Thank you for pointing out that the original BL700 is the best, I've had the Yoshiko YC4000 and the Uniross both short listed. I very pleased I just seen your comment in time. I hate cheap Chinese copies of anything including most of their batteries etc. Saved me buying scrap for the landfill
It's good to know that there's a professional charger I have got rid of loads of others have a look at the one I bought on my channel the one I bought it's a lloytron. The video is called to do with saving power.
@steve
Hey Steve. Thanks for the video!
I have a BQ-CC65 for Panasonic Eneloop Pro batteries. The battery power goes up to 1.51v.
When I take out the battery and quickly put it back in, it goes down to 1.41v and starts to charge again up to full....which takes a good little while :/. I tested a new Powerowl with 3 Eneloop Proband they react the same, if this helps.
Do you happen to know: Is the battery charger faulty or is this normal for batteries? If you could kindly recommend a fast battery charger for my Eneloop Pro or Powerowl. Thanks in advance!
Hi thanks so much for this video! Do you know if a battery is taking days and days to discharge and refresh does that mean it’s dead? Some have said ‘null’ as soon as I’ve put them in so I’ve assumed this means they’re dead. But some just keep going and nothing happens. Thanks
I have this charger and I am trying to figure something out. If I stick a partially charged battery in it obviously doesn’t know immediately how many mAh is in it so is the mAh number shown on the screen the total charge it has put in? So for example if a 2000mAh battery is put in but already has 1500mAh of charge in it would it show up to 500 on the mAh charge screen and then say full?
Hello mate. I've just bought a UniRoss UCQ001, it's exactly the same as the charger you use - Bought on this review, so thanks for that. Just wondering do you know of any item to truly test how much is power is left in standard non-rechargeable batteries. Nice one
Thanks for watching
noticed the number 2 batt has only 400ma shown at full charge. however its a 900ma battery ! not charging fully ??
hi - thanks for making this video - super helpful
how often do you discharge a battery or run the discharge/test function ?
thanks
once every 10 or so charges, it takes time.
thanks :)
Watch the video....he tells you.
Hi ! Very interesting video. Sorry for the basic question but: how do you know if a battery is used and there is no use to charge it anymore? Thanks
Not really. The charger would basically say there was no battery present and you would then know. You can discharge and charge, then do the maths with the charge taken over time and also decide.
Steve Allan Thanks for the reply. I found a similar Technoline model BC 700 in Amazon I will be happy to try. Your video helped me to decide on what to buy. I definitely need something else than the dumb charger that puts 8 hours on a battery without even thinking !
Can you get this device to show the actual current max capacity of a rechargeable battery?
I don't think so unless you use it to fully discharge and do some maths.
Hey Steve, just watched your review and having bought one of these a few months ago I've come to only needing to use it now and can't get the eneloop batteries to register on the device, it is always showing me the 'null' text, wonder if there's anything I need to do apart from trying to fit them in differently (which isn't working at all)?
I assume they are not Lipo style batteries. All I can suggest is you remove and refit them. It could be that the batteries are totally dead and can not be recovered and the null.
@@airgunology they're NiMH and this would be their first charge 😱
@@Pequito Sounds like you let them discharge too much.
@@airgunology is that a thing? First time owning rechargeable batteries. Does that mean I should try and charge them before the charge goes completely?
I’ve had this problem too. If you put any batteries in a standard ‘dumb’ charger first for about 15 mins they will have enough charge to work in this charger. Hope that helps.
Hi mate
Great vid, very clear and informative on something i find fairly confusing.
This is a very basic question but what does the voltage display mean? Is it the voltage held in the battery or the output of the battery or what? It makes no sense to me.
I’m current-ly charging 4 brand new Eneloop pros 2 read 1.39 volts 1 reads 1.40 volts and the other is switching between the two.
In simple terms, voltage is the "power" needed for your device to run. The MaH is the capacity of the battery or how long it will supply a voltage. Normal batteries the voltage goes from 1.5v downwards to about 1.1v overtime. These batteries stay at 1.5v for 7 hours.
Also the voltage will never stay constant in normal batteries for the reason I gave above. Those env batteries will go to a voltage say 1.4 to 1.5 and then fluctuate as the power is drained, shown by the voltage changes you are seeing during the charging process.
Steve Allan thanks steve :)
Steve Allan
So run for 7 hours it will give off 10.5 volts? Why don’t they write the capacity as 10.5 volts?
Not quite. They will run at 1.5v for approx 7 hours due to the 3000mah rating and the technology inside the battery. You haven't quite got the terminology correct and not as simple as 7 x 1.5v
Thank you for the video. I have a question (because I don't know nothing about battery) I am using 2450mAh and 2700mAh, this charger work only until 1000mAh or could work nice for me? Thank you again.
The charger will work out the capacity of the battery automatically and set up the charge to safely fill to it's max level.
SUPERB Video Steve......although this is a cheap clone of the SUPERB Technoline BL700N.
Indeed it is!
I have been charging small battery for 20 years and never use an intelligent charger . Now I will !
Does it charge the dead flat batteries?
It will attempt to trickle charge very low batteries and recover them, but totally dead ones it might struggle with.
Hi-ho all. As I write this, I am literally holding (on my gut) my "La CROSSE® TECHNOLOGY" Model:BC-900, which is BASICALLY the same as you are reviewing. I believe "La CROSSE" is the 'origin' producer, selling the unit design to many other companies to sell. Also, there ARE several different 'models' of the same charger, usually different in minor cosmetics, like the 700 and the 800 - VERY slight differences. I seem to recall there might also be difference in the amount of currents choice or such. The one I have... actually FOUR!... do not have the 'USB' charger. I just might need to get two or more of these... :-). But, other than my three FUNCTION buttons being straight across, and the numbers of the four SELECTION buttons being shaped a bit differently/larger and on the top of the buttons, everything else IS pretty much the same... which is GREAT!!! Oh, HEY. I see MY model just to the right on the page here... "10 Best NiMH Chargers 2017". How 'bout that?!?! I got my four about ten or so years ago and ALL are just like new.
This is a GREAT charger. The main thing I like is being able to REFURBISH, or re-condition batteries. It will charge / discharge / charge / discharge a battery repeatedly until it obtains what ever the result it is 'looking' for. Also, I like being able to choose the charge rate (miliAmps) as you sometimes want a FAST charge (not good for the battery) or the really SLOW for over night. It's a great thing to be able to SEE the amount of voltage your battery has.
The are a few other functions that make this a big value for the money. I highly recommend this to all friends and family who are looking for a really good charger, and for a great price.
You did a good job with this video, buddy. Keep up the great effort.
thanxs Michel. Yes there are loads of Chinese copies of this model of charger all with slight differences. This copy seems to work well for me and hence the video on it. Thanks for the comments, very useful for other people watching.
I have another question.
This charger only tells me how many mAhs it’s put in in the session. It doesn’t seem to show how many is in the battery. It just says “full” when it’s full. Can any chargers tell you how many mAhs are in? Surely this is way more important.
As far as I now, no chargers can do this as it is not possible to measure MAH remaining. The only way (that this charger will report) is to drain the battery, re-charge it and measure what it puts in. What you are asking for is not possible any other way with any charger.
What’s the difference between discharge vs discharge & refresh?
refesh cycles the batteries between charge and discharge and prolongs the life of the rechargeable battery. It is recommended to do this 1 in every 10 charges.
Thanks for the reply Steve. What I meant is when would you use the discharge (only) feature instead of the disparage & refresh option?
Why not use lipo batteries and chargers
You can if you have them and appliances work with them. That is another video, this is about NiMH and NiCD batteries.
Cheers. btw, there's no milliamps "per hour". Q=It, the charge is current times time and the current is just current.
So you charge a 2000mAh (milliamp hour)battery at 1000mA (milliamps), it takes 2 hours. There is no "amps per hour". There are milliAmpHours per hour but that is just milliamps.
Thanks for putting me right.
I agree with Jim Yelland, commenting below. The Youshiko YC4000 IS a cheap copy of the Technoline BL700N. The Youshiko cannot charge a battery from dead flat and it has NO OVERHEAT Temperature Control (although it claims to have). Take a look on here at the TWO excellent (seperate) videos comparing the Youshiko to the Technoline. Pay the few extra quid and get the Technoline.BL700N (must be the BL700N, not the BL700).
Good info and thanks
Does it auto cut off?
Yes
@@airgunology Question does different charger increase more charge time?
(More Cycle)
Yikes, don't buy shitty NiMH batteries with memory effects. Eneloop does not have any of that, you can charge whenever you feel like it.
I have one of these. It is not professional. It can't handle kick starting dead batteries. It is ok, but there are plenty of better options. This is just a rebadged Uniross charger.
Hi Steve. Just found this video and this charger looks exactly what I have been looking for. However, I have also just found a video on the tube showing the same charger but under a different brand. The different branded version Is literally half price of the Youshiko. I would appreciate your opinion before I go ahead and purchase one or the other.
Here Is the link showing the cheaper version : th-cam.com/video/XXrdEmymF2w/w-d-xo.html
Many different branding on this model of charger. Many companies sticking their logo on it and not surprising you found ti cheaper elsewhere.
Thanks Steve, appreciate your swift reply. Keep up the videos mate, they are always good to watch 👍
The Yoshiko YC4000 is exactly the same as the ones badged by 7dayshiop, Uniross, Tenergy, Powerstation, etc which are all (technically inferior) Chinese copies of the original Technoline BL700. I own both the Yoshiko and Technoline versions and was disappointed to conclude that the Yoshiko is simply a low quality imitation of the Technoline BL700N by comparison in terms of build qualty and accuracy.
Didn't you look at this before you put it on line ? Holding the charger is bad lighting...A good video gone bad.
One of my earlier videos and I am an amateur, not professional video person.
