A survival radio battery adapter is provided for survival equipment to operate with commercially available rechargeable batteries sealed in a rugged, watertight battery compartment. The survival radio battery adapter comprises a battery compartment, an adapter coupler, an adapter means having surge protection, voltage regulator and voltage conversion devices, with the adapter coupler being connected to the battery compartment and the battery compartment containing sufficient commercially available rechargeable batteries. The battery compartment is configured to provide a watertight seal when closed. The preferred embodiment is an AN/PRC-90 survival radio battery adapter. In another embodiment, this invention provides a survival radio battery adapter for the AN/PRC-112 D survival radio comprising a battery compartment connected directly to the survival radio, with a surge protection device being included in the battery compartment, and other power management devices already included in the survival radio so that it operates with commercially available rechargeable batteries. This invention also provides battery adapters for survivability equipment.
