After fully charging/conditioning batteries, ProSport's Energy Saver mode will monitor batteries and automatically maintain batteries only when needed to maintain a full state of charge, resulting in maximum reserve power performance and lower operating costs. Features include safety ignition, reverse polarity, over temperature and voltage protection, and current limiting.

ProSport Onboard Chargers are 40% lighter than older technology epoxy-filled chargers. Multistage charging delivers fast charge times, and all models have 2 digitally selectable performance charge profiles for Flooded/AGM and GEL batteries. During short- or long-term storage, ProSport Chargers automatically recondition batteries once a month, extending the life and performance of your batteries.

Distributed on Demand charging technology takes 100% of the available charging amps and distributes them to any one battery or combination of all batteries as needed for faster charging.
