An adapter cap for a sealed lead acid battery comprises a non-conductive housing having a base perimeter adapted for flush alignment with the top surface of a battery which is dimensioned to encompass the tab terminals of the battery. Conductive material is secured to the housing and extends through a portion of the housing which is configured as a female connectors adapted for sliding engagement with the battery tab terminals to provide an electrical coupling external to the housing. A recharging jack is disposed in the housing which is electrically coupled to the portions of conductive material. The housing including an aperture therein to receive a mated component for the recharging jack, whereby the adapter cap provides a charging connection that protects the battery tabs and a recharging connection electrically coupled to the battery tabs.
