I have a 2002 Volvo with a big battery , its original and probably
just worn out , but I check it at night after driving its 100% @13.3v
and in the morning its 75% 12.5v or so. But strangely it only takes 5
minutes at 15 A. to get to 100% or 13.3v . Most likely battery is just
old and bad, ideas. How do I check a draw of amps on a battery to see
if I have a short. Or do I just get a new battery and worry later or
not at all.
