Topcon 312672101 Rechargeable NiMH Batteries for LS-B100 Machine Control Receiver - BT-68Q

The Topcon BT-68Q (Part No. 312672101) is the genuine OEM rechargeable NiMH battery designed specifically for Topcon's LS-B100 and LS-B110 series machine control grade receivers. Engineered for demanding jobsite conditions, this battery delivers up to 50 hours of continuous runtime on a single charge — enough capacity to carry crews through multiple full shifts without interruption. When your grading or excavation operation depends on consistent, accurate machine control, the BT-68Q ensures your receivers stay powered and on grade throughout the workday.

Overview & Jobsite Applications

Topcon's LS-B100 and LS-B110 grade receivers are core components of laser-guided machine control systems used on grading, dozing, scraper, and excavation equipment. The BT-68Q is the factory-specified power source for these receivers, maintaining the stable voltage supply required for accurate laser detection and reliable grade signal output. Whether you're finish-grading a subdivision, cutting a pad for a commercial building, or managing drainage slopes on a large civil project, a depleted receiver battery can bring a machine to a standstill. The BT-68Q's extended 50-hour capacity minimizes that risk, making it a practical investment for any fleet running Topcon machine control.
