Thank you for uploading the video on this battery charger very informative, so I subbed keep those videos coming and I loved the format of explaining everything, excellent.👍
Delta Peak, what this charger does is monitor the batteries voltage, and when it senses the Change in Peak voltage, the charger turns off with the battery being fully charged as it assumes the battery is full when in fact it might not be. I would use anywhere between 3 to 6Mv the other way you could ascertain what is the correct Mv for your rechargeables batteries would be If you find that the charger has stopped charging, but the batteries are not warm, then they have probably "false peaked", then you would have to start over again charging (When NiCd and NiMh batteries until they are fully charged, they should be slightly warm (not hot) to the touch this is a good way to gauge the delta peak for your batteries are charging properly real old batteries I would hit them with 8Mv as you will find the 3 to 6Mv range wont be enough for older batteries again trial ands error takes a while but you will get the jist of things real quick. As for setting a voltage limit switch it off altogether that is for racers who need a specific voltage for their car racer motor and is of no use to us charging batteries for household devices. I have the SkyRC 3000 it is a fantastic wee charger well not wee as it is a big brick I ordered two X Powerex MH-C9000PRO, as they terminate correctly and are very accurate the very best NiMH/NiCD AA & AAA chargers you can buy, I am going to purchase another NC2500 pro from AliExpress saw it advertised for $38. I ordered Eneloop pro and Eneloop standard batteries so how many AAA & AA batteries do I own way too many would be 30 of each maybe that is not a lot but it is a lot for me along with Duracell some made in Japan Yeehaaaa which are Eneloop batteries festooned with a Duracell wrapper and some made in China, BOOOOOO which as we all know are not as good..
Many thanks for your great information. I didn't have a clue about Delta Peak or voltage limits, so this has really helped. The RC in SkyRC would indicate that certain features are specifically for remote control hobbyists. I just use my batteries for TV/AC/BluRay remote controls and camera accessories, etc. I was also interested in your comments (from someone who obviously has a lot of knowledge of the subject) about the Powerex MH-C9000PRO. I have been really impressed with this charger, and actually bought a second one recently. It's far better than my Liitokala and Vapcell chargers, but this conflicts with many comments I have received in my videos. There are a lot of Liitokala and Vapcell fans, but it isn't the same for Powerex. One person left some scathing comments about Powerex chargers and batteries, but I think it's a great charger. It doesn't look as fancy, isn't as flexible for battery type/size, doesn't show as much information, but it does the job a lot better. I've read reports suggesting that the IKEA Ladda batteries that I use are also Eneloops festooned in a different wrapper. I like these batteries and think they represent good value for money. Thanks for taking time to respond and to further my education!
@georgesilverhawkstrailcame2297 Thanks, George. I don't have any deep knowledge of rechargeable battery technology. However, since doing these videos, I have seen from comments that some people out there really know their stuff. I've learnt a lot from the comments.
How Delta peak charger works with the millivolt drop back voltage setting is in the rc racing world the theory was adjusting this allowed for a little more punch our of your sub c size nimh batteries. So some racer would set the mv to 3 because when the battery nears it's peak voltage the voltage drops down in mV. So if battery is starting to be charged at say 1.444 volts then the battery then drops 1mv at a time so then it would go to 1.443 1.442 so forth. Well that 3mv means the charger will end charge when it drops 3mv. or to whatever ever setting it drops back. However the choice of your MV setting will chargre more or less per say resulting in a higher temp at end termination. Lower the number the hotter the battery will be. Any value over .03 volts for a single cell may cause the cell not to peak. A high value of charge current will also give hotter batteries. A value of .08 volts should fully charge most battery packs with one peak. Read page 4 and 5 about delta peak. This is from a very high end charger back in the day. You can trust this info and research this on the net but this will help a lot with nimh. I use .03 to .04 for nimh and .05 to .07 for nicd's i had back in the day. It's pretty neat. Here is the link to the info on batteris for page 4 and 5 but you can read the whole thing as this company competition electronics no longer making the charger they still update firmware and is a great company. notices.patrickmodelisme.com/telecharger/Comp_Elec/Comp_Elec_Turbo_35_Manual.pdf Take care guy. you might have better luck with this sky rc renewing older nimh cells after you learn those extra settings. I have recover many myself. Take care.
@@PhilUKNet Welcome. That charger was designed by a electrical engineer correctly like a piece of test equitment. Not like the cheap ones today that are not so accurate. That manual tells a lot about battery charging. Take care.
@rcdude86 Thanks again for the link and the information. After spending some time with this charger, I get the impression it was made by people who know what they're doing for people who know what they're doing. I have a lot to learn on the subject!
sometimes when fast charging batteries they can stop charging too soon - step charging enables you to go fast in the beginning and then top off gently :) there might be other uses beyond my knowledge
Thank you! I guessed something like this, but I wouldn't know how to configure the different steps to charge the battery to its optimum capacity. This is a great charger, but to make the most of some of its features requires a level of knowledge that is greater than mine!
@@PhilUKNet Your welcome. The Powerex MH-C9000PRO is a real wee power house of a NiMH/NiCD AA & AAA charger it is very accurate and terminates the charge very accurately I would use nothing else to charge my rechargeable Eneloops as I trust it more to do that job correctly it is very accurate indeed and it comes highly recommended the SkyRC 2500 pro is a fantastic charger and it is fantastic for charging refreshing batteries especially when you can insert X 6 batteries. It took me ages to read up on the different charging methods I shortened the life of quite a few batteries teaching myself how to charge my batteries properly in the beginning as I hadn't a clue what I was doing now that is all in the past and can charge batteries properly but as you rightly stated in your other video the Powerex MH-C9000PRO does it correctly and it even gives you the amount of charge rate and discharge rate to use you certainly can not go wrong as all the guess work is taken out of the equation and you will end up with a perfectly charged battery that you can recharge for years and never shorten the life of that battery unexpectedly. The SkyRC 2500 pro is a fantastic wee charge as well and so compact it makes my RC MC 3000 look antiquated none the less I will keep it and use it as I do you certainly can not have enough battery charges. So I think I will stop buying any more battery chargers and be happy with my lot it is a pity the Powerex MH-C9000PRO was not out at the time I got into charging my own batteries suppose then it would have made me lazy and I would never have learnt anything as that RC 3000 has quite the menu and is better navigated using the APP as it makes it more user friendly but you have to fill everything into it per battery you wish to charge. Oh I got to thinking about the Delta Peak Mv setting start at 3Mv as setting it at that higher delta-peak setting doesn't really charge a NiMH pack more than a lower setting, as you may assume your charger is putting more energy into the battery when in fact it isn't all that extra energy isn't being absorbed by the pack, all you're really doing is generating more heat so I found my preference was 3 mv for Niamh and 5 mv for NiCad that's what I would use as that worked really good for me but please don't take my word for it experiment its just down to personal preference feel the batteries after a charge that is a good gauge if they are hot then nock it down one until you get the battery warm on the other hand I wouldn't go lower than 3Mv and some people just leave it at 5Mv and be done with it if the battery is hot or not but then fools tread where angels wouldn't. I like to play about with the settings and then literally feel the results works every time as I like to play it safe using the Powerex MH-C9000PRO you don't have that worry that's why it is a fantastic wee charger you simply cant do it wrong. Oh that deal I explained to you SKYRC NC2500 Pro N for £38 that was for the NC2200 after taxes the NC2500 Pro worked out costing $85. Please keep me posted how you get along with the charger. 😀
This is an interesting charger, and yes it’s more flexible then the PowerEx, but most of settings such as adjustable trickle charge current and rest times, I’m use isn’t an advantage over the PowerEx Pro or original. Their trickle currents are at ideal rates, and the same goes for resting batteries… one hour is best, any more is no benefit, and less is less than ideal. I do like the break-in mode, and I believe that is an advantage. How much of an advantage, I’m not sure. All in all, this is a proper piece of work. After the holidays, I will likely pick one of these up and fiddle with it. I’m thinking that perhaps I use one of these strictly for breaking in batteries. I know what the manufacturer says about the breaking in… 3 to 6 months. I disagree with that, especially with low self-discharge batteries. This batteries (Eneloop, LADDA, Tenergy Pro, Centura, etc.), and designed to self-discharge very slowly and hold capacity for very long periods. Now standard NiMH batteries that set… then yes, I would refresh them, if they have sat for months unused. Your video was very informative, and I now understand the user interface of the charger… which I greatly appreciate. This video will be especially helpful for anyone interested in this charger, and especially someone buying their first charger/analyzer. All my best wishes to you and yours.
Oh, and those LADDA NiMH batteries… those are remarkable cells... very impressive performance. Hands-down my very favorite cells. Oddly… they actually seem to perform, very slightly, better than the Eneloop Pro AA batteries. This honestly has been my experience with them. I exclusively use LADDA NiMH AAs, in my trail cameras… been using them for four years now. I do use some Eneloop and Eneloop Pro batteries.
@georgesilverhawkstrailcame2297 Thanks again, George. SkyRC really know their stuff, and they make products for people who have advanced knowledge of rechargeable battery technology. To be honest, the level of knowledge required surpasses my own knowledge, but I am learning slowly through the comments I receive! It was through TH-cam that I found out about Ladda, and that is all I buy now. I order them directly from IKEA in Thailand. There is a huge problem in this part of the world with fake goods, especially batteries, memory cards, etc. Many batteries bought online are fake, but when buying Ladda from IKEA, I know they are genuine. They also perform very well. Many of the brands you mentioned, I haven't seen for sale here.
