Don't want to spend a wad of cash on AA batteries to power your gadgets? Trim down your spending by cracking open the case of a single 6 volt battery which sells for about $5. Inside you'll find a whopping 32 AA batteries! Considering that you can get 8 watch batteries from a 12-volt battery and 6 AAA batteries from a 9-volt battery, this isn't surprising, but since AA batteries are the most popular among the three, this should yield considerable savings. Thanks, Richard & Lew!
