Batteries and Power 3
• The Lithium-ion batteries are rated to operate from –20 °C to +60 °C (–4 °F to
+140 °F)
• Do not allow a battery that is in storage to discharge to below 5 V.
Charging the Lithium-ion battery
The rechargeable Lithium-ion battery is supplied partially charged. Charge the battery
completely before using it for the first time. If the battery has been stored for longer
than three months, charge it before use.
The internal battery charges fully in 8 hours when connected to a suitable power
source.

WARNING – Charge and use the rechargeable Lithium-ion battery only in strict
accordance with the instructions. Charging or using the battery in unauthorized
equipment can cause an explosion or fire, and can result in personal injury and/or
equipment damage.
To prevent injury or damage:
– Do not charge or use the battery if it appears to be damaged or leaking.
– Charge the Lithium-ion battery only with a Trimble product that is specified to charge it.
Be sure to follow all instructions that are provided with the battery charger.
– Discontinue charging a battery that gives off extreme heat or a burning odor.
– Use the battery only in Trimble equipment that is specified to use it.
– Use the battery only for its intended use and according to the instructions in the product
documentation.
When the internal temperature of the receiver is greater than 50 °C (122 °F) or less than
5 °C (41 °F), the internal battery charger stops charging and the receiver’s display
shows
Charger Disabled, Temp Limited . However, the receiver will still draw its power
from the external DC source, extending the operating time in the field.
When the external DC voltage is less than 15 V DC, an X is displayed across the battery
status icon on the front panel display, which indicates that the internal charger is off.
Storing the Lithium-ion battery
If you must store a Lithium-ion battery for long periods, make sure that it is fully
charged before it is stored, and that you charge it at least once every three months
while it is stored.
Do not allow a battery that is in storage to discharge to below 5 V. A battery that
reaches deep discharge level (5 V or less) cannot be recharged and must be replaced.
(To protect a battery that is in use from deep discharge, the receiver switches power
sources or stops drawing power when the battery pack discharges to 5.9 V.)
All batteries discharge over time when not in use, and they discharge faster in colder
temperatures. Do not store the receiver at temperatures outside the range –40 °C to
+70 °C (–40 °F to +158 °F).
