Batteries for the

The receiver has one internal rechargeable Lithium-ion battery.

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 and 12 hours as a rover during measurement operations using the internal radio.

The receiver can also be powered by an external power source that is connected to the Lemo or modem port.

All battery operation tests are carried out with new, fully-charged batteries at room temperature and with full receiver configuration operational. Older batteries, at temperatures significantly higher or lower than room temperature, will have a reduced performance. Receivers operating with reduced configuration will have a higher performance.

Battery safety

Charge and use the battery only in strict accordance with the instructions provided.

Internal lithium-ion battery

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.

Avoid contact with the rechargeable Lithium-ion battery if it appears to be leaking. Battery fluid is corrosive, and contact with it can result in personal injury and/or property damage.
To prevent injury or damage:

  • If the battery leaks, avoid contact with the battery fluid.

  • If battery fluid gets into your eyes, immediately rinse your eyes with clean water and seek medical attention. Do not rub your eyes!

  • If battery fluid gets onto your skin or clothing, immediately use clean water to wash off the battery fluid.

Connecting the receiver to a vehicle battery

Use caution when connecting battery cable's clip leads to a vehicle battery. Do not allow any metal object or jewelry to connect (short) the battery's positive (+) terminal to either the negative (-) terminal or the metal of the vehicle connected to the battery. This could result in high current, arcing, and high temperatures, exposing the user to possible injury.

When connecting an external battery, such as a vehicle battery, to the receiver, be sure to use the Trimble cable with proper over-current protection intended for this purpose, to avoid a safety hazard to the user or damage to the product.

Charging the Lithium-ion batteries

The rechargeable Lithium-ion batteries are 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.

Charge and use the rechargeable Lithium-ion battery only in strict accordance with the instructions.

To prevent injury or damage:

  • Discontinue charging a battery that gives off extreme heat or a burning odor.

  • Never attempt to remove, replace, or repair the battery yourself.

  • If the battery requires attention, send the receiver to an authorized Trimble Service Center.

The internal battery charges fully in 8 hours when connected to a suitable power source.

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 not able to support the power drain, an X is displayed across the battery status icon on the front panel display, which indicates that the internal charger is off.

Using the Lithium-ion battery as a Universal Power Supply (UPS)

The internal battery will only charge from an external power source as long as that source can support the power drain, for example, an AC power adaptor. The receiver is supplied with an AC power (also known as mains power) supply unit that recharges the battery inside the receiver when it is connected through the adaptor to the modem port or the Lemo port. When you use the receiver on large projects, from a permanent or semi-permanent base station location in a site trailer, Trimble recommends that you use this power supply at all times to keep the internal battery charged. This provides an uninterrupted power supply and will keep the site operational for more than 10 hours after a power failure.

Keep all batteries on continuous charge when not in use. You can keep batteries on charge indefinitely without damage to the receiver or to the batteries.

Removing the rechargeable Lithium-ion battery

The internal Lithium-ion battery should be removed only at an authorized Trimble Service Center. If the battery is removed at an unauthorized service center, the remaining warranty on the product will be void.

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).
