8.3 Charging the Battery
A fully charged battery can power the system for about 18 hours. When the battery is plugged into the
charger and charging, all the LEDs will flash. It takes about 3 hours to fully charge a fully discharged
battery.
During normal operation, the LEDs are lit to indicate percent charged.
If the ERR LED is lit, it means you need to re-calibrate the battery by fully discharging and then fully
charging.
