Compatible models

Voltage and charger limits

Each cell delivers 7.4 V and 5800 mAh for 42.92 Wh of energy. The built-in protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating. Only the listed Topcon chargers are supported; other chargers may not terminate correctly or could trip the safety circuit.

Two-cell pack constraint

The product ships as a matched pair, so single-battery spares are not available from this SKU. Buyers who need only one replacement cell or a different voltage platform should look elsewhere. The 3*2*2 inch form factor fits the battery compartments of the compatible instruments listed above.

Questions about this item

Should I choose the 2-pack or buy a single battery for my Topcon BT-65Q?

The listing is a 2-pack of 7.4 V 5800 mAh cells giving 42.92 Wh each, so you get two ready-to-swap spares for long survey days.

What does the 5800 mAh rating actually deliver on a GTS-900 total station?

At 7.4 V the 5800 mAh pack stores 42.92 Wh, typically running a GTS-900 or FC-2500 for a full field session before needing a recharge.

Which charger standard works with these BT-60Q compatible packs?

They charge on Topcon BC-30, BC-30D or BT-30 units, so any of those existing chargers will handle the 7.4 V lithium-ion cells.
