What should you do to prolong the running time of Dewalt DE9094 battery?

If no permanent damage has been done to your cordless Dewalt power tools battery, you may be able to improve its run-time. The correct procedure for charging your Dewalt DE9094 power tool battery is as follows:

• Let the tool battery sit out of the charger for a least 2 hours until the battery is at room temperature.
• Discharge the Dewalt drill battery under normal use. Remove the battery, once you feel a loss of power from the tool. Do not tape the trigger ON.
• Place the Dewalt DW9095 drill battery in the charger overnight to allow for a full charge on each individual cell (A minimum of 8 hours at room temperature).

The outside temperature affect cordless drill batteries performance and life. If the power tool 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 Dewalt drill 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.

If there is no difference in run-time, there is either permanent damage or the electric cordless tool battery has reached the end of its usable life. In either case, the original Dewalt battery should be replaced.
