Using the Five Slot charger

The Trimble Five Slot charger can charge up to five SX12 scanning total station batteries one after the other.

The five slot 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 connect the charger to power, connect the AC to DC converter (2) to the DC input connector (3) on the charger and then connect the AC to DC converter to 100 V–250 V 50 Hz–60 Hz power using the power adapter (1) for your country of use.

CAUTION – Before charging or using the battery it is important that you read and understand the battery safety and environmental information. See Battery safety.

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

    CAUTION – Ensure that nothing obstructs the vents in the back of the charger. The bottom of the charger is hot during charging.

  2. Connect the charger to the AC to DC converter and then connect the AC to DC converter to 100 V–250 V 50 Hz–60 Hz power.

    The charger scans the slots for a battery. The green light flashes on the slot that is being scanned.

  3. Place the battery in any of the slots.

  4. Charging takes approximately 3 hours per battery at room temperature. If several batteries are charging in the battery charger, the batteries will be charged sequentially, from left to right.

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 amber LED for a slot is flashing, the battery occupying this slot requires conditioning. See Conditioning the battery.

  • If the amber LED turns off, the battery is revived. If the amber LED stays on, the battery is no longer functional and needs to be replaced.

A battery that has been subjected to 20 consecutive incomplete charge/discharge cycles requires conditioning and will trigger the conditioning‑required indicator. You can use the Five Slot charger to perform a conditioning cycle.

  • A full charge/discharge cycle is defined as one that uses more than 90% of the battery capacity.

  • A battery also requires conditioning if the power gauge (a count of the battery capacity) in the battery is misreading the battery capacity by more than 8%. 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.

  • Using all the battery capacity before charging will reset the indicator.

To condition the battery:

  1. Press the conditioning button (1) on the back of the charger. Amber LEDs become solid, and all green LEDs start to flash. Release the conditioning button.

  2. The conditioning cycle begins. This involves:

    1. Charging the battery completely.

    2. Discharging the battery until the voltage is below the low-end conditioning threshold.

    3. Charging the battery again.

    CAUTION – The bottom of the charger is hot during conditioning. Do not touch the bottom plate.

    Ensure that the vents in the back of the charger are unobstructed and that the charger is on a flat and level surface.

  3. Conditioning a single battery can take up to 24 hours. Conditioning five batteries can take up to 60 hours.

NOTE – If you press the conditioning button again when conditioning is in progress, you cancel conditioning. To succeed, a conditioning cycle must be uninterrupted.
