Maintaining Drill / Power Tool Batteries

When do I recharge my drill battery?

There is a belief that you have to completely discharge (flatten) your drill / power tool battery before recharging it.
 
 Some even place the battery in the torch until the light goes out or….

 The old favourite, place a rubber band around the trigger until the drill stops turning.

This is incorrect!!!!!!

The best advice, according to the Owl, is to use the drill / power tool until it stops performing the way it should (usually when you only have one or two screws left to fasten).  That is the best time to recharge. So it might be advisable to have a second battery to continue with while your battery is recharging.

By completely discharging the battery, as in the incorrect belief, you are in fact shortening the life or number of cycles your battery was designed to supply.

At Battery Wise we will give you the correct advice for all your battery needs.
