High-capacity Li-ion replacement for Topcon total

The Kastar BT-65Q is a 7.4 V 5800 mAh lithium-ion pack rated at 42.92 Wh. It replaces Topcon BT-60Q, BT-61Q, BT-62Q, BT-65Q, BT-66Q and GMS-2 cells in survey instruments such as the FC-200, FC-2200, FC-2500, GPT-7000i, GTS-750, GTS-751, GPT-7500, GTS-900, GPT-9000 and ROBOTIC models.

Compact brick format with built-in protection

Measuring roughly 3 by 2 by 1 inch, the battery slots into the instrument’s existing compartment without adapters. Integrated over-charge, over-discharge, over-voltage, over-current and over-heating safeguards meet UL 1642 and CE requirements, so the pack can be left on the charger or in the field without extra monitoring.

42.92 Wh capacity decides runtime per charge

The single figure that determines whether this unit suits a job is the 42.92 Wh rating; crews needing longer continuous operation between charges should verify that value against their instrument’s draw. Buyers who need a different voltage, chemistry or form factor will not be served by this pack.

Questions about this item

What voltage does the 7.4V lithium-ion chemistry deliver to the Topcon total station?

The pack supplies a nominal 7.4V that matches the original Topcon BT-65Q specification for FC-200, GTS-900 and GPT-9000 series instruments.

What physical space must the 3×2×1 inch pack clear inside the battery compartment?

The cell measures 3 by 2 by 1 inches, so the compartment must accept those exact external dimensions for a secure fit.

How is the pack installed in a Topcon GTS-750 and which step is often missed?

Slide the battery into the compartment until the latch clicks; the step users miss is verifying the click to confirm the contacts are fully seated.
