bullymom, as far as batts go, you should label, charge, use, and discard in sets. the reason, the power from 1 battery will pass through the other battery in a full loop. if one of those batteries varies from what it's "used to", failure, reduction in life, and over discharge may occur. I mark mine with a sharpie with a solid line of black on 1 pair of batts. you could yse markers, paint, masking tape, electrical tape pull tabs in different locations, etc. not everyone thinks this is nessisary but it's easy enough to do and it makes me feel better.
I had read that somewhere on the forum. I used a sharpie. I was surprised at how quickly they charged up. Then I found out from the supplier that they come about 80% pre charged. So I'm loaded and ready to roll.
