Recalibration of the electronics is achieved by fully recharging the battery followed by a
full discharge. Depending on the storage history of the battery pack, the smart battery
may require calibration when brand new
.
The LCD Fuel Gauge is located at the same end of the battery as the pull tab.
The LCD fuel gauge employs a „five‟ segment LCD. Each segment represents
approximately 20% of the batteries remaining capacity. Each segment of a fully charged
battery represents approximately 30 minutes of run time.
If fuel gauge recalibration is needed, the red LED on a calibrating charger will
flash upon insertion of the battery. This provides feedback on the accuracy of the
fuel gauge and avoids unnecessary calibration cycles.
The user can either calibrate the fuel gauge and charge the battery, or just charge the
battery.
Calibration takes longer than charging and it may not be convenient to go through the
calibration cycle.
To recalibrate the fuel gauge, press the button on the front of the charger.
The charger will automatically begin to charge the battery if the button is not pressed.
The blue LED will flash to indicate that the battery is undergoing the recalibration cycle.
During calibration the discharge resistors will be cooled by the fan. Removing the
battery, or pressing the calibration button again will re-start the process from the
beginning.
At the end of this procedure the blue LED will stay constant indicating a fully calibrated
fuel gauge. Warm environments can cause calibration failure - keep the charger away
from direct sunlight or heat sources.
