Replacement Battery for Trimble Survey Gear

This 7.4 V 2600 mAh lithium-ion cell replaces the Trimble EI-D-LI1 pack used in R7, R8, MT1000 and 5700 receivers. It also fits Spectra Precision SP60 and SP80 GNSS units plus a long list of Hemisphere, Navcom and Pentax survey instruments. The black housing matches the original form factor.

Simple Snap-In Swap

The pack slides into the battery cavity of each supported device without tools or soldering. Alignment ribs on the casing prevent reverse insertion, so the only common mistake is forgetting to latch the retention clip after seating the cell. No firmware update or calibration routine is required by the battery itself.

Limited to 7.4 V Nominal Systems

The chemistry delivers a fixed 7.4 V nominal output and 19.24 Wh capacity; it cannot power equipment that expects a different voltage or a higher watt-hour rating. Devices with proprietary fuel-gauge chips may report capacity inaccurately until a full charge cycle completes. The cell is not designed for parallel or series string configurations.
