Bought brand new, Diehard Platinum Group 34 AGM RC:135 min...
I never charged it once. Took it home, tested it with a multimeter and it reads 12.99 Volts. Is it all set to go use it in my boat or do i have to charge it still?
I think it's a good practice to go ahead and charge any new battery before use. Maybe just a trickle charge overnight on that one, just to make sure you're 100%.
