Replacement Battery Pack for Topcon Survey

This pack includes two lithium-ion batteries rated at 7.4V and 5800mAh each, delivering 42.92Wh of energy. They replace the Topcon BT-60Q, BT-61Q, BT-62Q, BT-65Q and BT-66Q cells used in GTS and GPT total stations. The bundle also supplies a matching AC wall charger with a foldable flat plug for compact storage.

Check Instrument Model

Verify that your total station appears in the supported list covering GTS-750, GTS-751, GTS-900, GPT-7000i, GPT-7500, GPT-9000 and ROBOTIC series. Confirm the original charger is a Topcon BC-30, BC-30D or BT-30 so the supplied unit matches the required input of AC 100-240V and output of DC 8.4V 600mA.

Suits Survey Crews Needing Spare Power for Listed

Field teams running compatible Topcon stations gain a ready spare pair and a travel-friendly charger with red and green LED status lights. Users with instruments outside the named GTS, GPT or FC series, or those requiring a different battery voltage or chemistry, should look for a dedicated kit matching their hardware.
