Can auto computer have a problem with a battery under 12 volts

Asked by Jul 05, 2016 at 05:09 PM about the 1995 Chevrolet Chevy Van

Question type: Maintenance & Repair

Sometimes I let my van sit for week without charging. When I do this it seems
to run more rough. But if I start it up every few days and keep it charged up I
don't have this problem. Is this model more prone to this. My 2002 doesn't
have this problem.

Your battery should be at 12.3V. If it is under 12 volts, the van won't start and you will get weird electrical issues. If the battery is over 5 years old, you need a new one. Since the van sits for weeks without starting, purchase a "Battery tender". it all trickle charge your battery when not in use.

Thanks Tom, It does start, even when the battery shows a little under 12 volts. It just runs a little rough for a while, I guess until the computer gets readjusted. I never had this problem before they started putting these dumb computers into cars.
