What this battery replaces

This lithium-ion pack is a direct replacement for Leica Geosystems survey instruments including the ATX1200, ATX900, Flexline total stations, GPS900, GRX1200, GS20, Piper 100, Piper 200, RX1200, RX900, SR20 and System 1200 GNSS receivers. It matches part numbers 724117, 733270, 772806, GBE221, GEB21, GEB211, GEB212, GEB221 and GEB90. Survey crews who need a fresh power source for these specific models will find the correct fit here.

Installation and common pitfalls

The pack drops into the battery compartment and locks with the original latch; most technicians complete the swap in under a minute. A fully decoded chip communicates with the instrument exactly like the factory cell, so no firmware steps are required. The only frequent error is seating the connector slightly off-centre, which prevents the unit from powering on. Online videos demonstrate the alignment, and the supplier answers email questions within a day.

Capacity and voltage that decide fit

The cell delivers 6800mAh at 7.4V, yielding 50.32Wh of energy. That capacity and voltage combination is what determines whether the battery will run your instrument for a full field day; if your original pack lists different figures this unit will not be compatible. The physical envelope measures 71.72 x 39.16 x 39.40mm and weighs 208.0g. Buyers whose equipment calls for a different voltage or a higher watt-hour rating should look elsewhere.
