A cordless drill serves many functions. It can be used to make minor fixes and repairs around the house and can also be used on a construction site. Several manufacturers make different brands and models of cordless drills, all with different specifications, speeds and features. However, the battery packs used in the various cordless drills all remain the same. The drill battery packs contain either Ni-Cd or Ni-MH batteries. If the cordless drill is no longer charging or holding a charge, it may be time to replace the batteries.
Step 1: Remove the cordless drill from the charging station. Turn the drill off.
Step 2: Remove the battery pack. The battery pack is located on the bottom of a cordless drill and can be loosened by pressing two tabs, one on each side of the drill. Once loosened, pull the battery pack downward to remove it.
Step 3: Remove the battery cap. It usually just slides off, but it may be held in place with a small screw, depending on the cordless drill manufacture. If there is a screw, use a small Phillips-head screwdriver to unscrew the screw and then slide off.

If the battery on your cordless drill does not hold a charge or it runs down quickly, it may need to be replaced. Cordless drill batteries can wear out over time. The performance of the battery can also deteriorate if the battery has become damaged. Using a multimeter, cordless drill batteries can be tested to determine if they need to be replaced.
Step 1: Plug the battery in and charge it for at least an hour. Unplug the battery when you are ready to test it.
Step 2: Touch the multimeter probes to the two battery terminals. Be sure to touch the negative probe to the negative terminal, and the positive probe to the positive terminal.
Step 3: Check the voltage indicator on the multimeter. A fully charged battery should test at least 1 volt higher than the voltage that is listed on the battery. For example, an 18-volt battery should test at 19 volts or higher.
