Replacement battery for Topcon survey instruments

The Kastar BT-65Q is a 7.4V 5800mAh lithium-ion cell delivering 42.92 Wh, designed to replace the Topcon BT-60Q, BT-61Q, BT-62Q, BT-65Q, BT-66Q and GMS-2 packs. It suits surveyors who need a direct swap for total stations such as the FC-200, FC-2200, FC-2500, GPT-7000i, GTS-750, GTS-751, GPT-7500, GTS-900, GPT-9000 and ROBOTIC models. Buyers whose equipment uses a different battery form factor or voltage should look elsewhere.

LCD USB charger powers up to three cells

The bundle includes a compact charger measuring 3*2*2 Inch that accepts 5V 2A via Micro USB from a wall adapter, vehicle socket or computer. Intelligent LCD readouts show charging status and remaining capacity for each bay. Output is 8.4V 0.5A per channel, allowing three batteries to charge simultaneously. Users without a convenient USB power source will need to provide one separately.

Verify your instrument model before ordering

Compatibility is limited to the Topcon battery, charger and total station models listed above. No other brands or series are supported. Confirm that your device accepts a 7.4V Li-Ion pack and that you have access to a 5V USB supply for the charger. If your instrument requires a different chemistry, voltage or connector, this kit will not work.

Questions about this item

What USB standard does the LTD2 charger use and what power input does it require?

The charger uses a Micro USB connection and requires a 5V 2A 10W power input from a USB wall adapter, car charger or computer port.

What physical size is the BT-65Q battery and will it fit my instrument?

The battery measures 3 by 2 by 2 inches and replaces Topcon BT-60Q, BT-61Q, BT-62Q, BT-65Q, BT-66Q and GMS-2 packs used in FC-200, FC-2200, FC-2500, GPT-7000i, GTS-750, GTS-751, GPT-7500, GTS-900, GPT-9000 and ROBOTIC total stations.

How do I charge the battery and what common mistake should I avoid?

Insert the battery into the LCD USB charger, connect the supplied Micro USB cable to a 5V 2A source, and watch the intelligent display; do not use a lower-current USB port or the charger will not deliver its 8.4V 0.5A output per slot.
