Battery Packs
Your tool uses a 24 Volt DEWALT battery pack. When ordering replace-
ment battery packs, be sure to include catalog number and voltage.
Extended Run-Time battery packs deliver more run-time than stan-
dard battery packs.
BATTERY PERFORMANCE
Some chargers have a tune-up feature that optimizes battery pack
performance. Your charger may provide Automatic Tune-Up™ Mode
or manual (i.e., push button) Tune-Up™ mode. For information on this
feature, please see the appropriate section below. Because batteries
slowly lose their charge when they are not on the charger, the best
place to keep your battery pack is on the charger at all times.
USING AUTOMATIC TUNE-UP™ MODE
The Automatic Tune-Up™ Mode equalizes or balances the individual
cells in the battery pack allowing it to function at peak capacity. Battery
packs should be tuned up after every 10th charge/ discharge cycle or
whenever the pack no longer delivers the same amount of work. To
use the automatic tune-up mode, simply place the battery pack in the
charger and leave it for at least eight hours. The charger will cycle
through the following modes.
1. The red light will blink continuously indicating that the 1-hour
charge cycle has started.
2. When the 1-hour charge cycle is complete, the light will stay on
continuously and will no longer blink. This indicates that the pack
is fully charged and can be used at this time.
3. Whenever the pack is left in the charger after the initial 1-hour
charge, the charger will begin the Automatic Tune-Up™ Mode.
This mode continues up to 8 hours or until the individual cells in
the battery pack are equalized. The battery pack is ready for use
and can be removed at any time during the Tune-Up™ Mode.
4. Once the Automatic Tune-Up™ Mode is complete the charger will
transition to a maintenance charge; no indicator light shows the
completion of the Automatic Tune-Up™ Mode.
USING THE MANUAL TUNE-UP™ MODE
The manual Tune-Up™ mode equalizes or balances the individual
cells in the battery pack at its peak capacity. This mode takes up to 8
hours to complete. Battery packs should be tuned up weekly or after
10 charge/discharge cycles or whenever the pack no longer delivers
the same amount of work.
1. To tune up your battery pack, place the battery in the charger as
usual. The red light will blink continuously indicating that the
charge cycle has started.
2. Press the Tune-Up™ Mode button any time after the charge cycle
has started. The red light will stop blinking momentarily, blink
quickly 3 times, and then resume blinking continuously. The
charger is now tuning up the cells in your battery.
3. When the Tune-Up™ mode cycle is complete, the light will stay on
continuously. The pack is fully charged and may be used at this
time or left in the charger.
4. If you select Tune-Up™ Mode and then change your mind,
remove the battery from the charger. After 5 seconds, insert the
battery into the charger. The normal charge cycle will begin.
Charge Indicators
HOT/COLD PACK DELAY
When the charger detects a battery that is excessively hot or exces-
sively cold, it automatically starts a Hot/Cold Pack Delay, suspending
charging until the battery temperature has normalized. After this hap-
pens, the charger automatically switches to the Pack Charging mode.
This feature ensures maximum battery life. The red light flashes long,
then short while in the Hot/Cold Pack Delay mode.
REPLACE PACK
These chargers are designed to detect certain problems that can arise
with battery packs which would be indicated by the red light flashing
at a fast rate. If this occurs, re-insert battery pack. If problem persists,
