Help with charging a 6xAA Eneloop pack...

[Greenbean]

Greetings CPF,

I am hoping to purchase a single DC charger for one of my older (FM I believe) 6xAA carriers for a 2D mag.
Now if just removing all the cells and continuing to use the Eneloop included 4-bay charger is best I'll just do that.

I would like to utilize the DC plug in the end of the battery pack. It would certainly make charging easier.
What should I look for?
I'm assuming a generic charger might not be the best thing here...

Please educate me and send me off in the right direction to spend MORE money!

Thanks in advance,
GB

This is the unit I am referring to.

you could probably get away with charging them in series / parallel like that in an emergency but it`s not a good idea, it`s best to charge each cell individually and then try match them up as close as you can afterwards. it`s mismatched cells that cause the problems and that`s hard to monitor or correct when charged as a bundle like that. get an 8 bay charger that will do NiMH cells and that`ll be your safest bet for long term use of your batts.

Ok cool!

Thanks!!!!

I'll start researching an 8-bay,

I do have a Tenergy charger for my "C" and "D" NiMH cells, guess I could use it. I totally forgot I had it.

It may be a 4-bay though.

well it doesn`t have to be an 8 bay it just makes it easier to keep everything even, you could use a pair of those Tenergy`s instead and it should work if you keep and eye on them or even a different brand but that can make things a bit uneven.

Maha makes a few 8 bay chargers that are well regarded. Anywhere from $65-$100.

The MH-C801D is great. "Proper" charging currents too - 2A and 1A (soft charge) for AA cells.

Are you looking for something like this?

You can recharge all 6 Eneloops without removing from holder.
Just connect 7.2V output DC jack to female side of battery holder. Charger will stop charging after fully recharged.
It's always good to balance charging each cells separately once a while.

Looks good, Thanks FM!

A 6V-12V charger for a 2,4V battery?
If that works out?? :shakehead

 

[Greenbean]

The charger says it reads the voltage needed, and adjusts accordingly. The pack reads just over 8V with no load.

I can usually trust any recommendations made by FM.

Should I not?

So far I have assumed that one D cell has been replaced by three AA cells connected in parallel. That would have been a 2s3p circuit.

If you now say about 8V, then this is a pure 6s series connection. Then the charger fits perfectly and I take back all my warnings. :thumbsup:

A 6V-12V charger for a 2,4V battery?

The white battery holder with 6 Eneloops are connected all in series or nominally 7.2 volts, and battery charger I suggested can charge any battery pack of 5 cells, 6 cells, 7 cells, 8 cells, 9 cells and 10 cells if they are NiMH and connected in series.
As Green stated in post #10 charger can detect battery total voltage (number of cells) and charge accordingly.
A 2.4 volt pack of 3 parallel AA as first cell and D size as second cell in series not recommended to make such a pack or charge the pack.

 

[Greenbean]

So I am going to purchase the above mentioned charger,

I am having trouble finding the correct adapter to DC plug to use on the pack...any help would be greatly appreciated.
