Charging a pack or packs
1. Before charging, pack(s) must be properly connected to the charger. See “Connecting packs
to the charger,” earlier in this manual, for details.
2. Press the
Start/Stop
button for one second to enter Charging Mode.
3. You will see the following screens in sequence:
Checking Pack(s)
CHARGING Press
MODE for info.
4. While in Charge Mode, you can take the following actions:
To view pack and operating data:
Press the
Mode
button repeatedly to cycle through the
following screens. (These examples assume two packs are being charged; if one pack is
being charged, only the top line may appear in some screens.)

*Cells are numbered from 1 through n, where 1 is the first cell in the pack connected to Ch1, and n is the
last cell in the pack (if only one pack is being charged) or the last cell in the pack connected to Ch2 (if two
packs are being charged).
†For the charger to calculate internal resistances, a) pack discharge wires must be connected during
charging and b) pack must be at less than 80% fuel level. Internal resistances will be available for display
after about 12 minutes of charging, and will be periodically updated after that.
