What causes acid stratification in a car battery?
Acid stratification occurs if the battery dwells at low charge (below 80 percent), never receives a full charge and has shallow discharges. Driving a car for short distances with power-robbing accessories engaged contributes to acid stratification because the alternator cannot always apply a saturated charge.
Is acid stratification bad for batteries?
