Thanks.....there you go.....

Sorry to post for a old thread.

I need your help to understand how to charge AA and AAA with my charger.
My question it self may not be making sense...
I searched quite bit but never had any good clue.
Thanks in advance.

Charger: Venom Pro Charger
Batteries: AAA = Energizer 850mah 1.2V / AA = Energizer 2300mah 1.2V

My understanding: To Charge 4 AA or AAA in series
For AAA:
(850x4)=3400
3.4 x 0.2C = 0.68a = Charge Amp
End Voltage = 1.2 x 4 = 4.8

For AAA:
(2300x4)=9200
9.2 x 0.2C = 1.84a = Charge Amp
End Voltage = 1.2 x 4 = 4.8

Not quite right mate

You dont add capacity in series, it stays the same regardless of the number of cells

850 mah AAA
1c charge rate will be 0.85 amps
1/5c charge rate will be 0.17 amps

2300mah AA
1c charge rate will be 2.3 amps
1/5c charge rate will be 0.46 amps


A nimh cell will peak at around 1.45v

4 cells in series will peak at around 5.8v

Cheers

I see!
Thanks for your advice!

One more quick question.

is 1/5C charge adequate for these Enagizer NiMh AA and AAAs?

I use AA for RC contoroler(Spektram DX2X) and AAA for Kyosho MIniZ.

Depends on the charger you are using

If you use a dedicated slot / cell charger you can use higher rates

Most will handle up to a 1/2c charge rate

The lower the rate the better for the batteries

1/5c will be fine

If you want decent Nimh cells grab yourself some Sanyo Eneloop LSD (Low Self Discharge)

Cheers

Thank you again!!!

I don't know if anyone are actually gona read this but,when I'm using my venom pro plus charger on the eneloops,why does it get full at around 1000mah while charged at 0.2-0.3 amp ?
I have got a proper aaa battery tray with the proper dean plug soldered to to join my lipo charger.
What am I doing wrong ? Or is this normal ?

Are they triple A? I think those are rated at 750 min - 800 typical? If so, since some charge on a nimh will go off into heat, 1000 sounds reasonable, good even. How warm did the cells get?
