Everest & Jennings (Graham-Field) brand electric power chairs are something of an anomaly with their reverse polarity, but Monster Scooter Parts has the batteries and proper battery chargers to help you keep your Everest & Jennings power chair running its very best.

NOTE: Everest & Jennings scooters and power chairs require reversed polarity battery chargers. Standard polarity XLR battery chargers will NOT work with Everest & Jennings products.
