Centenex Electronics 2-Pack GPS Battery for Pentax Ei-D-Li1 Trimble 5700 5800

2-Pack GPS Battery for Trimble Survey Equipment

This two-pack supplies replacement power for Trimble 5700 and 5800 GPS receivers, transmitters and data collectors. It also fits the Pentax Ei-D-Li1 and HP PhotoSmart 912 series cameras. Each cell matches the original form factor for direct installation.

Lithium-ion cells without on-board fuel gauge

The batteries use standard lithium-ion chemistry and lack a built-in charge indicator. Users must rely on the host device to report remaining capacity. No balancing circuit or smart communication protocol is present in the pack.

This set upgrades ageing original packs that no longer hold a full day’s charge. The jump is worth it when field crews see run-time drop below a single shift or when swollen cells prevent proper seating.
