Just de-solder the red and black wires and pull out the battery. Put it in a plastic bag to stop it shorting out on anything metal or cover the terminals with tape. The battery must be recycled properly as it contains toxic cadmium. As long as the battery is not leaking then it poses no threat to you. Refitting the new battery is just as simple, re-solder the red wire to the +terminal and black to the -terminal. Be sure to charge the razor as you would a new one i.e. 8 hours. Hope this helps.

I replaced the battery in my Norelco shaver (model 7825XL). When I made the last solder connection, the razor began to run and will not stop. What next?

Check the ends of the batteries nearest the motor. If the batteries are touching the leads to the motor, this will supply constant power to the motor.

If you batteries were seriously corroded, it may have traveled to the switch and ruined it

Manual for Norelco 985RX Electric Shaver. Need to replace the rechargeable batteries.

I have successfully replaced the batteries two years ago in my Norelco 965RX shaver with two Rayovac AA Nicad batteries. Works as good as the original batteries. You must solder them in and solder a band (solder wicking works well) across the + and - terminals at one end.
