When using the LCD display: approx. 6 hours
When using the screensaver: approx. 7 hours
* 1-sec sampling, capturing to internal memory (SD1), new battery pack, and +25°C
environment.
* The running time depends on the operating environment.
* When the empty battery is charged in the GL220/820/900, the charging in about
80-90% will stop. Once disconnect and connect the AC adapter, or remove and
insert the battery pack. The battery pack charging is started in order to charge up
to 100%. (It depends on the remaining capacity.)
Mount in the main unit
approx. 4.5 hours
Because the battery is used together with the AC adapter, the power supply will be
switched automatically to the battery in the event of a power failure.
* The AC adapter is the primary power source.
