OER Battery Chargers and Maintainers

Keep a Fully-Charged Battery at All-Times

OER lightweight chargers/maintainers deliver optimal battery performance and feature a compact design with multi-stage charging, over-load, over-heat, and reverse polarity protection. A fully-charged battery is essential for an optimally running vehicle, whether on the street, track or trail. When batteries are allowed to drop below full charge regularly, they can experience premature failure, producing low cranking power, and increased charge times. OER Smart Charger and Maintainers are a must-have for your battery maintenance and storage needs.
