Replacement battery for Topcon total stations

The KingSener BT-52QA is a 7.2V 2700mAh lithium-ion cell built to replace the original battery in Topcon GTS and GPT surveying instruments. It delivers 19.44Wh of energy in a black housing and comes as a brand-new unit. The three-pin connector matches the factory layout for direct installation.

Survey crews needing a fresh power source

Field teams who require a reliable spare for daily staking, layout or monitoring work will find this cell a direct fit for the listed GTS-200 through GPT-4000LN models. It is not suited for users of other brands or for instruments that take a different voltage or pin arrangement.

7.2V 2700mAh lithium-ion specification

The 7.2V nominal voltage and 2700mAh capacity are the critical figures that determine compatibility; the instrument’s charger and fuel gauge are calibrated for these exact values. Using a cell with a different voltage or capacity will prevent correct operation.

Questions about this item

How do I install the KingSener BT-52QA battery and what step do people often miss?

Align the three-pin connector with the Total Station battery compartment, slide the pack in until it clicks, then verify the instrument powers on; the step often missed is confirming the latch fully engages.

What maintenance will the BT-52QA need and when should I replace it?

Keep the contacts clean with a dry cloth, store the pack at roughly half charge in a cool place if unused for weeks, and replace it once run time drops well below the 2700 mAh rating.

What limit appears first during continuous surveying with the 7.2 V 2700 mAh pack?

The 19.44 Wh capacity sets the runtime ceiling; under sustained use the voltage will sag toward the cutoff threshold before the cells overheat, ending the session.
