The energy taken from a battery must be replenished immediately. Batteries begin to sulfate (destruct themselves) at 12.4 volts. If you drive little, please check the battery every 6 weeks and be sure to recharge it from 12.5 volts - otherwise there is a risk of loss of performance and a significantly reduced service life! Connect seasonal vehicles to a suitable trickle charger!
