It is also worth noting the car alternator is also not built for charging the battery and is often incapable of doing so. The purpose of the car alternator is to keep a fully charged battery fully charged and a discharged battery can even cause damage to an alternator. Posted on Nov 25, 2017. Fifa 16 fhl editor.
