this battery, the LCD Fuel Gauge is located at the same end of the battery as the pull tab
and requires no actions to view it.
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
