I bought a 12v. battery, a deep cycle marine, for a little bass boat I have.
The battery is three years old now at least and has not ever been used.

I need a battery to spin my newly bought welder and figured this one would
be okay to get it going. But how long do you think it will last after that?
Should I just put a charger on it and try it? The battery has actually
spent a winter at below zero temps, but no signs of cracking or dry cells.
