P-Series Cable Battery
The battery inside the battery case on the cable may be replaced with any ER6V/3.6V, 2000 mAh battery. The connectors that are on the cable are noted below. Parker doesn't sell these batteries or the battery with the wire and connector. If you purchase a battery on-line that already has a connector, you may want to check to make sure it is a Molex 5263PBT or equivalent. Alternatively, you can buy the cable and add your own wires and connector, or use the connector off the old battery. Another alternative, is just to remove the connectors and splice the wires directly together.
