On Board electrical power tools are a necessity for boat owners on moorings and cruisers. These boaters must be more self sufficient!

Take an old rechargeable hand drill whose permanently mounted battery will no longer hold a charge and modify it. Often a new battery will cost more than the whole drill did when new.

1. Remove the old battery.

2. Wire the battery terminals to a cord with a 12 volt utility plug that will reach anywhere on your boat- or make an extension cord. Be sure that this wiring is not compatible with 110 volt wiring to prevent problems should someone else use it.

3. Don't worry if the drill was originally intended for less than 12 Volt, it will work just fine and in most cases give better service for intermittent use. If your old drill was not a reversing motor, it can be now with the addition of a reversing switch or plug.

This same modification can be used on any of the popular 9.6 volt or 12 volt rechargeable battery tools where it is not convenient to recharge the battery on a l10 volt charger.
