The Battery Tender Plus is a trickle charger with a microprocessor control unit that increases charging safety. The unit automatically adjusts for temperature and provides a full charge for the battery if necessary. The unit works with all lead-acid, flooded and gel batteries. It maintains the RV batteries in a fully charged state when the engine's alternator is not available to maintain the charge. When you attach the Battery Tender Plus to the vehicle, you can use the batteries to power electronics in the RV without draining their storage capacity.

The Battery Tender Plus can charge more than one battery in the RV if you connect them in a parallel or series configuration. The parallel connection provides the most options for charging, and the use of a series circuit limits how you can use the device.
