Charging the battery

Ensure that nothing obstructs the vents in the back of the charger.

The battery is supplied partially charged. Charge the battery completely before using it for the first time.

  • To charge the battery, use only a charger that Trimble recommends for charging the Lithium-ion battery.

  • If the equipment has been stored for longer than three months, charge the battery before using the receiver.

The charger operates between 0 °C (32 °F) and 40 °C (104 °F). Charging a battery at temperatures in the range of 0 °C (32 °F) to 5 °C (41 °F) will take longer than charging at room temperature.

To charge the battery:

  1. Ensure that the vents in the back of the charger are unobstructed.

  2. Place the charger on a hard, flat and level surface, to ensure that there is airflow around the charger.

  3. To apply power to the charger, use the AC to DC converter or 12 V vehicle adapter. The red LEDs light up with no batteries inserted in the battery slots. The charger automatically scans the battery slots for a battery.

  4. Place the battery in any of the slots. It can take up to five seconds to detect the battery. For an explanation of the LEDs, see LED status indicators below.

  5. Charging takes approximately three hours per GNSS receiver battery (P/N 76767) at room temperature. If two batteries are charging in the battery charger, the batteries will be charged at the same time.

Leave a deeply discharged or shorted battery overnight in the charger to attempt to revive the battery. A shorted battery is typically revived as soon as the slot is scanned. If the red LED turns off, the battery is revived. If the red LED stays on, the battery is no longer functional and needs to be replaced.

LED status indicators

Beside each slot are three LED indicators (red, green, and yellow) to display the battery status. The LED indicators can have the following conditions: Off, On, 1 Hz (one flash per second), and 2 Hz (two flashes per second).:

Troubleshooting and corrective measures

Battery is not detected (Does not change from only red LED on after battery insertion).

Issue

Solution

The battery is not properly inserted.

Properly insert battery into battery charger slot.

Battery contacts contaminated.

Clean the battery (for example, by inserting and removing the battery several times) or replace the battery.

Deeply discharged or shorted battery.

Leave the battery overnight in the charger to attempt to revive the battery.

Battery defective.

Replace the battery.

LED abnormalities occurring.

Remove any batteries from both slots and disconnect the AC adapter from the charger.
