Nickel Metal Hydride Battery
3.1.2 Battery Indicator Lamps
Press the indicator switch (green button) to indicate the battery’s residual capacity.
NOTE
Even if the battery is used correctly, its performance will deteriorate gradually. This battery uses an absolute capacity indication system,
which, after the battery is charged, lights the indicator lamps in accordance with the extent of the battery’s deterioration.
Residual capacity lamp indication system
Characteristics of the absolute indication system
After the battery’s performance level deteriorates gradually to below 80%, the fifth lamp will not light
even after the charging is completed. After it deteriorates further to below 60%, the fourth lamp will also
not light. Because this system gives an absolute indication of the residual capacity in accordance with
the extent of deterioration of the battery, it can accurately indicate the residual capacity.
