Replacement Battery for Focus 35 Total Stations

This Cameron Sino battery replaces the original power cell in Trimble Focus 35 and compatible S-series, VX and SPS total stations. It delivers 6800mAh at 11.1 volts for extended field sessions. The pack matches the factory form factor of 126.00 x 74.30 x 25.10mm and weighs 326.0g. A built-in protection circuit guards against overcharge, over-discharge and short circuits.

Survey Crews Needing a Direct Swap

Teams that operate Focus 35, S3, S5, S6, S7, S8, S9, VX, RTS573, RTS633, RTS655, RTS773, RTS873, SPS610, SPS620, SPS630, SPS700, SPS710, SPS720, SPS730 or SPS930 instruments can install this unit without modification. Buyers who require a different voltage or connector layout should look at other options. The 75.48Wh rating suits standard daily workloads but may not cover multi-day campaigns without recharging.

6800mAh 11.1V Capacity Decides Fit

The single specification that confirms compatibility is the 6800mAh / 75.48Wh capacity at 11.1 volts paired with the Trimble part numbers 79400 and 99511-30. Verify that your original battery carries one of these part numbers before ordering. The decoded chip communicates with the instrument exactly as the OEM cell does.

Questions about this item

How do I install this 6800mAh battery in my Focus 35 and which step is most often missed?

Align the 126.00 x 74.30 x 25.10mm pack with the battery compartment, slide it in until the connector seats firmly, then latch the cover; the step most often missed is fully seating the connector before closing the latch.

What maintenance will this 75.48Wh survey battery need over its service life?

Perform 2 or 3 full charge and discharge cycles when new to reach peak capacity; afterwards, no routine maintenance is required beyond normal recharging.

What is the first limit I will hit when running this 11.1V battery continuously on a total station?

The 6800mAh capacity determines runtime; under sustained load the pack will deplete before any thermal or voltage protection engages.
