Leica GEB221 / 733270 Rechargeable Battery for Piper 100 and Piper 200 Pipe Laser

The Leica GEB221 (part number 733270) is the factory-specified rechargeable lithium-ion battery for the Leica Piper 100 and Piper 200 pipe lasers. Rated at 7.4 volts and 4.4 amp-hours, this genuine Leica battery pack is engineered to deliver consistent, full-shift runtime without the voltage sag or premature shutdowns that come with third-party alternatives. When your pipe laser is the critical path on a sewer, storm drain, or conduit run, you need power you can trust — and the GEB221 is built to that standard.

Overview & Jobsite Applications

The GEB221 slots directly into the Leica Piper 100 and Piper 200 battery compartment with a positive lock and communicates with the instrument's battery management system for accurate charge-state readouts. Whether you're setting grade on a municipal sewer project, running conduit through a commercial structure, or dialing in drainage slopes on a residential development, this battery keeps your pipe laser operational through demanding conditions. Keeping a spare GEB221 on the truck means a dead battery never becomes a job-stopping problem.

Job Applications

Municipal Sewer & Storm Drain: Long-duration grade runs on municipal utility projects demand consistent power. The GEB221's 4.4Ah capacity supports extended setups without mid-job battery swaps interrupting your grade control workflow.

Commercial Conduit & MEP Rough-In: Electrical and mechanical contractors running conduit slopes through commercial buildings rely on the Piper's precision. A genuine battery ensures the instrument's self-leveling and grade readouts perform exactly as specified.

Site Development & Drainage: Civil contractors establishing drainage grades across large pads need uninterrupted operation. A spare GEB221 eliminates downtime and keeps the crew on schedule.

Trenchless & HDD Operations: Horizontal directional drilling and bore crews using the Piper for alignment need power reliability as much as accuracy. The GEB221 delivers both without compromise.

Frequently Asked Questions

Will the GEB221 work with both the Piper 100 and Piper 200?

Yes. The Leica GEB221 (part number 733270) is the factory-specified battery for both the Leica Piper 100 and Leica Piper 200 pipe lasers. It is a direct, drop-in fit for both instruments with no modifications required.

Is the GEB221 a genuine Leica battery or an aftermarket unit?

The GEB221 sold by Express Tools is a genuine OEM Leica battery — not an aftermarket or third-party reproduction. It is manufactured to Leica's exact specifications including cell chemistry, capacity, voltage, and battery management system integration.

What charger do I need for the GEB221?

The GEB221 is compatible with the Leica GKL311 multi-battery charger, which is the standard charging solution for Leica survey and pipe laser instruments. Always use a Leica-approved charger to protect battery longevity and instrument electronics.

How do I know when the GEB221 needs to be replaced?

Signs that your GEB221 is due for replacement include noticeably shorter runtime per charge cycle, the instrument displaying inaccurate charge levels, or the battery failing to hold a charge after being fully charged. Keeping a spare GEB221 on hand is the simplest way to eliminate battery-related downtime on critical grade runs.
