Compatible Topcon GPS Battery

This lithium-ion battery replaces original BT-61Q, BT-65Q and BT-66Q packs for Topcon FC100, FC2000, GPT-7500, GPT-9000, GTS-700 and GTS-7500 series controllers. Surveyors and field engineers using these instruments receive a direct-fit power source built to the same 7.4 V 4400 mAh rating.

4.4 Ah Capacity Extends Field Time

The 32.56 Wh cell delivers a full day of operation for compatible Topcon total stations and field controllers without carrying spare packs. Black housing matches the original equipment appearance and the lithium-ion chemistry holds charge during transport between job sites.

Compact 71.70 x 41.20 x 45.00 mm Form Factor

The slim profile slides into existing battery compartments on FC100, FC2000, GPT and GTS models without adapter plates or cable modifications. Li-ion construction resists memory effect so the pack can be topped up at any state of charge between measurements.

Questions about this item

When will the 4.4 Ah Li-ion pack need replacing under daily field use?

Capacity fades with charge cycles; plan on a new pack when run-time falls below useful levels for your Topcon FC or GPT series controller.

What limits continuous operation on the 7.4 V 4400 mAh cell?

The 32.56 Wh rating sets the energy ceiling; sustained high-draw surveying will hit that limit before thermal throttling becomes a factor.

Does the 71.7 × 41.2 × 45 mm battery get hot or noisy during all-day GTS-7000 sessions?

Li-ion chemistry runs silently and stays cool at normal survey loads; no fan or moving parts means zero audible noise.
