I guess I'm just looking to see if this is normal... I bought a set of 8 Powerex batteries and a Maha battery charger upon being highly recommended. The charger is awesome, however the batteries don't keep a charge if they aren't used. I'm finding myself having to remember to charge them just before I need them which is a real pain. Is this typical? If so, I'm just going to go back to my old 'cheap' Duracell's and Energizers.
