• The service life of a battery is affected byfactors such as the number of starts, driv-ing conditions and climate. Extreme coldmay also further decrease the battery’sstarting capacity.
• Because the battery’s starting capacitydecreases with time, it may be necessaryto recharge it if the vehicle is not drivenfor an extended period of time or if thevehicle is usually only driven short dis-tances.
• Never use a quick charger to charge thebattery. Only traditional types of batterychargers should be used.
