Recharging Optional Nickel Metal Hydride Batteries
See the NiMH Battery Charger and Battery Pack manual for complete
details on charging, error messages, battery specifications, etc.
1. Remove the battery end cap (end cap without connectors):
A. Wipe the outside of the end cap and housing dry, being careful to
remove any water at the seam between them.
B. Unthread the end cap by rotating counter-clockwise (use a wrench on
the white plastic bar if necessary).
C. Remove any water from the O-ring mating surfaces inside the
housing with a lint-free cloth or tissue.
D. Put the end cap aside, being careful to protect the O-ring from
damage or contamination.
2. Remove the battery pack from the housing:
A. The protective plastic plate over the battery cover plate prevents you
from completely removing the cap screws that connect the battery
pack to the 19plus V2 battery posts in one step. Each of the screws is
12 mm (1/2 inch) long, but the clearance between the cover plate and
plastic plate is only 6 mm (1/4 inch). Unscrew each of the three cap
screws just until they hit the bottom of the protective plastic plate.
The battery pack will walk out of the housing approximately 6 mm
(1/4 inch) because of the spring contacts at the bottom of the battery
compartment. Unscrew the cap screws again. The battery pack
will walk out of the housing again, and should now be disconnected
from the battery posts.
B. Pull on the cord to remove the battery pack from the housing.
3. Recharge the batteries:
A. Plug the battery charger into a suitable power source and turn on
power to the charger.
B. Connect the charger cable to the battery pack and charger.
The LED should show READY, and display the battery type and
measured voltage.
C. Press the Discharge button. The LED should show DISCHARGE.
This starts the discharge cycle, which discharges any remaining
battery capacity. Repeatedly charging without discharging may
damage the battery pack. The Discharge cycle takes approximately
110 minutes. When discharging is complete, the LED should
show EMPTY.
D. Press the Charge button. The LED should show Fast Charge
(it may also show WARM-UP CHARGE, REFILL CHARGE, and/or
TOP OFF during the charge cycle). The Charge cycle takes
approximately 2 hours. When charging is complete, the LED should
show BATTERY FULL.
E. Turn off power to the charger.
F. Disconnect the battery pack from the charger and the charger from
the power source.
