Topcon 314870704 Rechargeable NiMH Batteries for RL-200 Series Rotary Lasers - BT-67Q

Genuine Topcon Battery Engineered for RL-200 1S and 2S Rotary Lasers

The Topcon 314870704 (BT-67Q) is the OEM rechargeable NiMH battery pack designed specifically for Topcon RL-200 1S and RL-200 2S rotary lasers. This isn't a third-party substitute — it's the same battery Topcon includes with new RL-200 units, engineered to deliver reliable all-day power for grading, site prep, and concrete work where your laser can't go down mid-shift. When your current pack starts holding less charge or your crew is burning through batteries faster than before, the BT-67Q is the only replacement that guarantees full compatibility and rated runtime.

Overview and Jobsite Applications

The RL-200 series is a workhorse on earthmoving, foundation, and flatwork sites. The BT-67Q keeps it running through full production days without the guesswork that comes with off-brand packs. Proper OEM chemistry means the battery communicates correctly with the RL-200's internal management system, protecting against overcharge and giving you an accurate charge indicator reading — critical when you're coordinating a crew and need to know how much runtime you have left before a break. Whether you're running the laser on a tripod across a large slab pour or mounting it on a grade rod for single-person layout work, consistent power delivery keeps your beam stable and your grades tight.

Job Applications

Slab and Flatwork Pours: Concrete crews running RL-200 lasers across large slab areas need a battery that lasts the full pour. The BT-67Q's rated capacity supports continuous operation so your screed and rod crew stays productive from first pour to finish.

Site Grading and Earthwork: Machine operators and grade checkers depend on the RL-200's constant beam. A reliable OEM battery eliminates unexpected shutdowns during cut-and-fill operations where stopping to swap power sources costs real time and money.

Foundation Layout: Accurate elevation control during foundation work demands a laser that stays on. The BT-67Q keeps the RL-200 running through layout sessions without voltage sag that can affect instrument calibration or receiver sensitivity.

Utility and Pipeline Grade: Trench grade work often runs in remote areas where there's no convenient place to plug in a charger mid-job. Maximizing battery runtime with a genuine OEM pack means fewer interruptions and more confidence in the field.

Frequently Asked Questions

Is the 314870704 the same as the BT-67Q?

Yes. 314870704 is Topcon's part number for the BT-67Q battery pack. Both numbers refer to the same genuine OEM product. When ordering, either number will get you the correct battery for your RL-200.

Will this battery work with both the RL-200 1S and RL-200 2S?

Yes. The BT-67Q is the designated battery for both the RL-200 1S (single-slope) and RL-200 2S (dual-slope) rotary lasers. It is not cross-compatible with other Topcon instrument lines such as the RL-100 or RL-500 series.

What charger do I need for the BT-67Q?

The BT-67Q is designed to be charged using the Topcon BC-27 NiMH charger, which is typically included with the RL-200 instrument kit. Using a non-approved charger can reduce battery life and may void your warranty.

How do I know when it's time to replace my RL-200 battery?

Common signs include noticeably shorter runtime per charge, the charge indicator dropping faster than usual during operation, or the instrument powering down unexpectedly in the field. If your current pack no longer gets you through a full workday, replacement with a genuine BT-67Q is the most reliable fix.
