Questions about this item

Does the 2-pack include a charger or just the two BT-65Q batteries?

The pack contains two 7.4V 5800mAh Li-Ion batteries only. A compatible charger such as the Topcon BC-30, BC-30D or BT-30 must be purchased separately.

Should I choose the BT-65Q 5800mAh pack or a lower-capacity Topcon battery like the BT-60Q?

The BT-65Q delivers 5800mAh (42.92Wh) per cell, the highest capacity listed among the compatible Topcon models, giving longer field time per charge.

What does the 5800mAh rating mean when the battery is powering a Topcon GTS-900 total station?

At 7.4V the cell stores 42.92Wh, so a GTS-900 drawing roughly 5W can run for about eight hours on one battery, and the 2-pack doubles that runtime.
