Default How to store rechargeable battery

Hello all the sifu, just want to check with all of you how you store your rechargeable battery after playing? Maybe going to store for a month long. Please advise on below 2 types:

Ni-Cd
Ni-Mh

Thank you.

im a nitro guy but i got enough exp on batteries. my old batteries still functioning till now after 1 1/2 yrs rest.

Ni-CD: full charge at last use.
Ni-MH: half charge(eg.3300 -charge at 1500 or 2000).

when start using again: recycle back. charge, discharge, charge discharge.
im still using my nicd and nimh till now.
i charge back my nicd using Flex mode to waken it back. but for nimh, use linear as always. even after idling 1 yr, my 3300 still can fully charged at 3280. not bad i think. thats 1 yr. u know. but i guess, i use LRP charge. maybe becoz of that... kekekeke. shop promoter this.

Hi,
This is what I usually do to my batteries:
NiMH - discharge & equalise to 0.9v per cell. To store it for longer than 1 week, I normally re-charge with 500 or 1000mah after discharging & cooled down. If I plan to use the batteries again within 1 week, I just store it after equalising to 0.9v per cell.
NiCD - I fully discharge them and store it in a discharged state. In most cases, I even leave the NiCD in a discharge tray for 2 or 3 days before storing them in box.
That's just my 2cents. Cheers.

Can a very cheap wall charger to charge until this rate? Mean how to calculate it to charge how long?

recycle back, mean discharge 1st then full charge, 2nd discharge again and full charge again then can start use?

Hi tkhoo,
I wrote Discharge to 0.9v per cell, NOT charge.
Maybe you should get James Khoo to help explain.
I do not think the wall charger has that function to charge or discharge to specific levels. You might have to buy a proper charger-discharger unit to do this.
Kindly consult James Khoo or the infamous Moey Chee Cheong (not sure where he is now these days).
Cheers

Default Charger

tkhoo,

Charging and discharging as a pack(side by side or stick pack) can be done by most charger with LED display to what ever voltage you one. But to individually discharge all six to 0.9v, I don't think so. That you have to purchase a discharger. Now the million dollar question -

Does it make a difference if you discharger all 6 cells individually to 0.9 v and charge it as a pack ??

Hope some experience bros there could give me some light on this

Hi tKhoo,
Try sending a private message to JamesKhoo for his handphone number. He is a nice chap and have more than enough experience to hands on assist you. Maybe you should ask him where he and his members play so that u can join in the fun.

What would happen if I discharge the newer generation batteries down to 0.7volts per cell???

Would this harm the battery???

I know that you can discharge older GP3300 batteries down to 0.7volts without harming the battery but what about newer cells like IB3800, IB4200, GP3700 and GP4300????

If your using match packs, yes it does alot of difference.
But if the cells are just normal cells, the difference wont not be that much different.
Discharging cells down to 0.9v/cell is to avoid false peak when u charge them up.
