Operation

Battery charging

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

• To charge the battery, only use a charger that is recommended by Trimble for charging the Lithium-ion batteries.
• Charge the battery before using the equipment if it has been stored for longer than six months.

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 sufficient airflow around the charger.
3. To apply power to the charger, use the AC to DC power converter or 12V car battery adapter. The red LEDs light up with no batteries inserted to 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 LED display, see LED status indicators.

Charging takes approximately four hours per total station battery P/N 99511-30 and three hours per GNSS receiver battery P/N 76767 or P/N 92670 at room temperature. If two batteries are placed in the charger, the batteries will be charged at the same time except for two total station batteries P/N 99511-30 which will be charged sequentially.

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.

Conditioning the battery (valid only for Smart Battery P/N 99511-30)

With the 99511-30 battery, after a number of incomplete charge/discharge cycles the power gauge in the Smart Battery becomes inaccurate. The battery is still safe to use, but the power gauge may no longer be accurate which may decrease the battery run-time in the field. In this case a conditioning of the battery is required. This is a cycle of:

1. Charge battery completely.
2. Discharge the battery until the voltage is below the low-end conditioning threshold.
3. Charge battery again.

The need for conditioning is read out from the battery by the charger and is indicated by a solid yellow LED. Conditioning starts when the conditioning button is pressed by the user. There is one button for each slot. Only the batteries requiring a conditioning can be conditioned.

To condition the battery:

1. Press the conditioning button under the battery. The red LED becomes solid and the yellow LED start to flash. Release the conditioning button.

   Conditioning a single battery can take up to 24 hours. It is recommended that you condition the battery or batteries on a weekend.

2. If you remove the battery while conditioning is in progress, you cancel conditioning. To succeed, a conditioning cycle must be uninterrupted.

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).

Status	Red LED	Green LED	Yellow LED
No battery detected (means no battery present or battery defect)	ON	OFF	OFF
Battery detected (charging not started yet) Conditioning not required Conditioning required	1 Hz 1 Hz	1 Hz 1 Hz	OFF ON
Charging in progress Conditioning not required Conditioning required Over/under-temperature (charge is inhibited)	OFF OFF 2 Hz	1 Hz 1 Hz OFF	OFF ON OFF
Conditioning in progress	ON	OFF	1 Hz
Conditioning done (Charging after 30% battery capacity)	ON	1 Hz	OFF
Conditioning done (Battery fully charged)	ON	ON	OFF
Battery fully charged Conditioning not required Conditioning required	OFF OFF	ON ON	OFF ON
Power supply over/under-voltage	OFF	OFF	OFF
When Output Over-Voltage Protection (OOVP) or Output Over Current Protection (OCP) is on	2 Hz	OFF	OFF
