Tips for battery usage
Minimizing battery deterioration
The battery is a consumable and the deterioration of its performance and battery life is accelerated under
the following conditions.
–
Repeatedly charging the battery
–
Using, charging, or storing the battery in a high-temperature environment
To minimize battery deterioration and ensure longer battery life, keep the following tips in mind.
•
Charge in an environment between 10 °C and 35 °C (50 °F to 95 °F)
If the surrounding temperature is too high or too low, the unit’s indicator flashes in orange and the battery
cannot be charged temporarily.
•
Avoid charging more than once per day
Charging the battery too often will cause the battery performance to deteriorate. Therefore, the unit will
not charge the battery immediately after it is fully charged unless the remaining charge is reduced at a
certain extent to avoid overcharging.
Maximizing battery operation time
To maximize the battery operation time, keep the following tips in mind.
•
Reduce the screen’s power consumption
Reduce power consumption by pressing
(power button) to turn off the screen when not in use, or
by reducing the screen’s brightness level.
