How to Replace the Batteries in a Cordless Drill Battery

Cordless drills can be extremely useful in many different circumstances, from hanging up picture frames to home renovation projects. The cordless drills free you from the constant hindrance of electrical outlets and the entanglements drill cords always seem to knot themselves into. It may be useful, however, to have replacement batteries on hand, just in case the battery in use runs out of power.

1. Turn the power off on your cordless drill.


2. Hold down the battery lock button on the rear of the drill. The exact location of the locking button varies based on the make and model of the cordless drill.

5. Power on the cordless drill and you are ready to work.

Tips & Warnings
If the cordless drill battery charger for your drill battery is a rapid charger such as those found on some Ni Cad batteries, your battery may charge in as little as 4 hours.
Use caution when working with solar panels and keep them out of the sun until all components are connected as they start producing electricity as soon as the sunlight hits the solar panel.
When connecting the positive and negative wires of the battery, inverter and solar panels, make certain that you are connecting positive wires to positive posts and negative wires to negative posts. Failure to do so will short circuit the charging system and cause it to explode.
