The AgGPS RTK Base GPS receiver uses
an internal rechargeable Lithium-ion
battery, which can be replaced only at an
Authorized Trimble Service Center.
The receiver can also be powered by an
external power source that is connected
to the Lemo or modem port.
The operational time provided by the
internal battery depends on the type of
measurement and operating conditions.
Typically, the internal battery
provides 10 hours operation as a base
station.
Note – All battery operation tests are
carried out with new, fully charged batteries
at room temperature and full receiver
configuration operational. Older batteries,
at temperatures significantly higher or
lower than room temperature, will have a
reduced performance.
