On the other battery type (example shown below), the LED fuel gauge employs a 'four'
segment LED. Each segment represents approximately 25% of the batteries remaining
capacity. Each segment of a fully charged battery represents approximately 37.5
minutes of run time. For this battery, the LED fuel gauge is located on the front of the
battery and the user is required to press the small circular button next to the gauge to
determine remaining battery life, which is represented by green LEDs.
"Real-Life" applications rarely fully discharge a battery pack. Frequent partial discharges
are not a problem to your smart battery, however after repeated use in this way, the
accuracy of the fuel gauge may be reduced.
The smart battery has a built-in monitoring system which checks the accuracy of the fuel
gauge, based on the discharge history of the battery. This history is broadcast over the
SMBus and can be used by the host device to inform the user when to recalibrate the
electronic fuel gauge.
Recalibration
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
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.
