How to Charge a Cordless Power Tool Battery

Cordless power tools operate by using electricity drawn from a wall outlet and stored in rechargeable battery cells. Energy is transferred from the outlet to the battery through the use of a battery charger that plugs into the outlet. To get the most power and longest possible working time out of your cordless power tool, you should fully charge the Craftsman power tool battery after each use.

Disengage the throttle or activation switch on your tool; allow the motor and all moving parts to come to a complete stop.

Remove the battery from the tool. Refer to your tool’s operation manual for instructions regarding how to remove the battery.

Set the battery aside and allow it to cool for 10 to 15 minutes to avoid overheating the battery during the charging process.

Plug the tool’s battery charger into an active wall outlet. Use the charger that came with your tool; if you do not have the tool’s original battery charger, be sure to use a charger that matches the voltage of your battery. Consult your operation manual or your tool’s manufacturer to determine the proper voltage rating for your battery and charger. Mismatching the voltages of a battery and charger can result in poor battery performance, damage the battery or create an electrical fire.

Insert the battery into the charger. Verify that the battery is charging; if the light on your charger is red, the battery is currently charging. You will know that the battery is fully charged when the light on the charger turns green.

Remove the Craftsman 130279003 battery from the charger, unplug the charger and insert the battery into your cordless tool.

When you charge a new battery for the first time, allow the battery to charge fully before using the tool. Failure to do so will greatly reduce the life of your new battery.

Maximize the amount of time you can work with your cordless tool by charging the battery fully after each use.

Buy a backup battery. When your first battery gets low, charge it and use your backup battery to keep working without interruption.

Do not alter a Craftsman cordless drill battery unless you are an experienced electrician. Incorrect modification of a rechargeable battery’s components can result in malfunction, electrical fire or burns.
