My cordless drill has three batteries. Since, I really have no use for three batteries, I was thinking of using two of these batteries as power supplies for an amp and dac that I use. I know people usually use SLA batteries for this purpose, but I was wondering if I could do any damage if I tried to use the drill batteries. They are rated at 12v 1.7a. Thanks for any help.

Cordless drills normally use NiCd batteries. I don't see how you could cause any damage, just use the charger they came with.

generally, the only thing you have to watch out with are lithium-based batteries. I have heard of some newer drills using lithium-ion batteries, so you might want to double check that they're NiCds

Thanks for the help. They are definitely ni-cd, so I'll give it a shot and see how much run time i get.

It'll work but be kinda large, if you're not going to have it portable I'd just go with an AC-DC supply, the hyped benefit of using batteries is beyond reason and then you won't have to recharge them either.

Thanks for the advice. I figure this is a free (in a relative sense) way to look for a difference.
