There are a lot of different types of 12 Volt DC Battery Chargers. Franks Towbars & Exhaust can help with the selection of the type of DC battery charger you need for your specific application. The charges we use are 3 stage chargers from Australian owned companies. They are designed to charge lead-acid, gel and agm batteries from a 12 Volt DC vehicle battery. The charger will charge the auxiliary battery to the proper charge and with its voltage sensing feature via the ignition circuit ensuring the main battery is not depleted while the vehicle is not running. The charger is suited to all 12 volt negative earth systems in vehicles, boats, caravans and camper vans.

Features Include:
Boost Charging – Increases the voltage from the main battery allowing an auxiliary battery to be properly charged within an average driving time.
Reverse Polarity Protection – Protects the unit from reverse polarity damage from incorrect wiring.
Dual Input – Able to be powered from an alternator 12v battery or 12v solar panel.
