Usage and maintenance tips

Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge. In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge.
