I had to take a truck battery back to Wal-mart,and had an hour to kill,while they put it on the tester.I stumbled across the COOLEST gadget I've seen in awhile-a hand cranked,generator powered flashlight-with LED bulbs.no dead batteries to worry about,and no lights to replace.At 8 bucks,it was'nt too bad a deal.i've been wanting something like this for YEARS!
