WARNING – Do not damage the rechargeable Lithium-ion battery. A
damaged battery can cause an explosion or fire, and can result in
personal injury and/or property damage.
To prevent injury or damage:
– Do not use or charge the battery if it appears to be damaged. Signs of
damage include, but are not limited to, discoloration, warping, and leaking
battery fluid.
– Do not expose the battery to fire, high temperature, or direct sunlight.
– Do not immerse the battery in water.
– Do not use or store the battery inside a vehicle during hot weather.
– Do not drop or puncture the battery.
– Do not open the battery or short-circuit its contacts.

The Trimble R7 can be powered either by its two internal batteries or
by an external power source connected to Port 2 or Port 3. The charge
provided by the internal batteries depends on the type of survey and
operating conditions. Typically, one battery provides about 3.5 hours
of power during an RTK survey using the internal radio, and about
5 hours during a survey without the internal radio.

The external power source is always used in preference to the internal
batteries. When there is no external power source connected, or if the
external power supply fails, the internal batteries are used. The
internal batteries are drained in turn, and the receiver automatically
switches to the full battery when the first battery is drained.

If no external power is supplied and both internal batteries are drained,
none of the data that you have logged is lost. When internal or external
power is restored, the receiver restarts in the same state as when power
was lost. For example, if the receiver was logging data, the data file is
not corrupted, and when power is restored the receiver resumes
logging with the same settings as before.
