Lead acid batteries are kind of strange. They share a property with

and longevity.

I'm not sure that's correct. I recently saw a reference that basically says the deeper you discharge a lead acid the less life you get. I'll try and find that again.




Nicads like being discharged to near 0 better though.

They used to develop a memory. I believe that problem has been solved.

I've just found a couple of stories about people seriously injured by flashlight explosions involving C123s. They were exposed to hydrofluouric acid gas and had long term lung damage. I wouldn't have expected enough chemical in those small batteries but i guess I was wrong.
