*Hello... I am storing a few rechargable whipper snipper batteries in my

freaking forget about them and they'll charge for a freaking week before I
remember. (I'm 51 and my mind is toast...70"s were real good to me lol)

Decent chargers won't overcharge batteries but if this is cheap crap,
you could just put them on a timer and charge them an hour a day.
Your bigger worry is storing the batteries outside in the shed.
Depending on where you live, that'll cook 'em just as sure as
overcharging will.
