OK I'll be getting a new battery but would like to no why?
I had a dead battery(slow crank,wouldent start) reading @11.??volts on multi meter.I have a anti gravity jumper and it starts right up with that.
So I put it on the battery tender and its full at 12.50 v(or 12.65 .I forget)but still has the slow crank after cranking it will read @12.50.
why with 12.50 would it still need a jump?bad cell?
Yes battery is old ,probably 7years
