Topic: Are My Batteries Ruined?

[lds490]

I've got some AA NiMH that I use in a battery pack.  I  left them in the pack (not connected to anything) for about a week.  When I tried to use them again I discovered they were fully discharged.  I think I read that NiMH batteries should never be fully discharged.  Are these batteries now dead?

no, NIMH batteries are actually supposed to be cycled like that, just try to charge em, i bet they come back to life just fine
