Compatible Sumitomo GPS Models

This lithium-ion battery replaces the original power source for Sumitomo JR-6, T-66 and T-81M receivers. It also fits Furukawa S218 and S218R units using part numbers BU-6 or S944. Survey crews can swap cells in the field without tools.

Voltage and Capacity Rating

The pack delivers 7.4 volts and 1600 milliampere-hours for 11.84 watt-hours of energy. That single figure decides whether the cell matches the instrument’s power budget; a different voltage or capacity will not operate the receiver correctly.

Sustained Field Operation

Li-ion chemistry holds a steady voltage through long stake-out sessions instead of sagging after a short burst. The 1.6 Ah rating supports extended logging cycles, and the black casing resists UV exposure during daily outdoor use.
