OEM Topcon AD-15ED-2 Battery Charger — Keep Your Rotary Laser Ready for the Next Shift

The Topcon AD-15ED-2 (Part No. 1012845-02) is the factory-original 110V wall charger designed specifically for Topcon's BT-74Q NiMH battery packs. Whether you're replacing a lost charger, outfitting a second set of batteries for back-to-back shifts, or stocking a spare for your crew, this OEM unit delivers the correct charge profile to protect battery longevity and keep your rotary laser running at peak performance. Sourced directly through authorized Topcon distribution channels, this charger is the manufacturer-approved solution — not an aftermarket approximation.

Overview & Jobsite Applications

Professional grade rotary lasers like the Topcon RL-H5A, RL-200, and related models are only as reliable as their power supply. The AD-15ED-2 charger plugs into any standard U.S. 110V outlet — job trailer, gang box power strip, or site office — and restores your BT-74Q pack to a full charge so your crew isn't waiting on equipment. Ideal for general contractors, excavation crews, concrete and masonry trades, and survey teams who depend on precise grade and level references throughout a full workday.

Job Applications

Grade Verification on Earthwork Sites: Excavation and grading crews running Topcon rotary lasers all day need a charged backup battery ready. Keep this charger in the site trailer to cycle batteries between the field and the outlet.

Concrete Flatwork & Formwork Layout: Concrete crews using laser-guided screed systems or elevation control can't afford downtime. A dedicated AD-15ED-2 charger ensures a fully charged BT-74Q is always standing by.

Finish Carpentry & Interior Leveling: Interior trades using rotary lasers for suspended ceilings, partition layout, or flooring reference benefit from uninterrupted power — especially on multi-floor commercial builds where returning to a charging station takes time.

Survey & Layout Crews: Land surveyors and construction layout professionals working extended field days can rotate two BT-74Q packs — one charging on the AD-15ED-2 while the other powers the instrument.
