Really? Now that's something I do once and never again. Tell me more.
As far as batteries: I bought a good battery charger (LaCrosse BC-900) and I'm surprised how different each battery can be in a pack of four. The charger has multiple modes, one of which is discharge/recharge. In that mode the batteries are discharged before being recharged. The display shows the discharge rate, time of discharge, etc.
Sometimes in a pack of 4 rechargeables, one battery will take 5 or 6 hours longer to discharge than the other three. There is a difference.
