To you knowledgable folks,
I have a 105ah 12v deep cycle battery that has met it's expiry date.
It met its expiry premature due to the fact that I bought one of those cases for it that have the buttons on it to show how much charge there is. Full/half/recharge etc and that button had be come stuck and drained the battery to 7v... And now it won't charge above 7.74v :)
Expensive lesson learned.
My question is though....:
I'm setting up some LED lights (build my own array with +/-3.v LEDs ) and thought, I might be able to use the battery for that purpose. Saving the new battery for the fridges etc. I guess I'd be using a lot of resisters but it would not be a total waste of a battery. Any thoughts on this?
Cheers
Marcel
