Best Practices for Longer Dewalt Power Tool Battery Life
- You should stop using the Dewalt power tool battery as soon as you feel a substantial decrease in power from the cordless drill. Completely running down a Dewalt DE9094 drill battery may damage it. Do not tape the trigger to run down the battery.
- If the batteries are too hot (105°F or higher) or too cold (below 40°F), the batteries will not take a full charge. Attempting to charge batteries outside the 40°F-105°F range can result in a permanent loss of run-time. When batteries are being charged and discharged, a chemical reaction is taking place, and if it is too hot or cold the chemical reaction is disturbed causing a loss of run-time.
- The Dewalt power tool battery chargers have a maintenance mode which allows batteries to remain in the charger, maintaining a fully charged pack until the user is ready to work. If Dewalt cordless drill batteries are stored outside of the charger, they will discharge naturally, 15-20% the first 24 hours, 7-10% the next day, and about 1% every day there after.
