I have a Powerex 204W with Powerex 2300MH batteries. I have two sets of four, and sometimes leave a set in the charger for several weeks at a time. Is this OK, or is it harmful to their life?

In my charger's manual it states that batteries should be left in the charger until needed. I dont think weeks on end will have a bad effect.

I'm guessing that is a MAHA charger you have – I think PowerX just makes batteries. I read a fairly technical analysis of that and the conclusion was that you don't want to leave them on trickle charge for weeks on end. It wasn't specific to the MAHA, which might have a low enough trickle charge that it doesn't matter. I have a MAHA and a larger charger that takes 8 batteries, both with a trickle. I turn them off after a day or so.

Hello St. Barnard,

I am afraid that in spite of the advertising claims, you will get better life from your cells if you don't store the cells in the charger. It is OK to leave them for 24 hours, but after that pull them.

Lingering slow charges tend to form large crystals which result in lower capacities from the cell. Fortunately, all it takes is a few charge/discharge cycles to bring things back to normal.
