Charger for Voltphreaks 16V batteries. This and only this charger must be used to charge a Voltphreaks 16V battery. If using an alternator instead to maintain the battery during use, we recommend adjusting alternator voltage to 16.75 to 17.5 volts.
* Charging times depend on many factors. Avoid running any accessory loads while charging the battery, as this will prevent the battery from getting fully charged. It is best to unhook battery from circuit when charging, as voltages above 18V can be encountered which may damage electronics on the car.
