anybody need about 10 mostly-good 9v batteries?

[LyleH]

I finally figured out what to do with the 9-volt batteries in our smoke detectors that I change twice a year. I got 2 of these, which are 9-volt batteries with a small casing with a on/off switch and an led lightbulb. I left one on continuously, and it lasted for a week! They're surprisingly bright. I paid $26 (including shipping) for 2 of them from Amazon. There are other models around, and there may be better deals around. (Pak-lite-LED-Flashlight-Basic-Economy)
