Up to two packs can be mounted
<When LCD is ON>
Battery pack x 1 (brightness MAX): approx. 3 hours
Battery pack x 2 (brightness MIN): approx. 6 hours
<When LCD is OFF>
Battery pack x 1: approx. 5 hours
Battery pack x 2: approx. 10 hours
* 20 channel terminals, 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
Battery pack x 1: approx. 5 hours
Battery pack x 2: approx. 10 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.
