I got a new battery from advance auto last weekend because my 3.5 years old OEM couldn't handle the chicago winter. Its a autocraft gold from johnson control which I think its the same battery as Duralast gold from autozone.
Anyway, I bought one of those little battery monitors that goes into the cig lighter adapter. It reads 14.1-14.4 while car is running which I think its good. But when car is off it reads 12.1 - 12.2
Isn't good battery supposed to read around 12.5 - 12.7?
I waited for awhile to make sure all the electrics go off.
Would cold weather effect voltage reading? I also have gauges and nitrous system but they are wired on keyed source.
