Cameron Sino Battery for Garmin Edge 800, 810 1000mAh 3.7V

Direct replacement for Edge 800 and 810

This lithium-ion cell matches the original Garmin KE37BE49D0DX3 pack used in the Edge 800 and Edge 810 GPS computers. It supplies 1000mAh at 3.7V and fits the 51.00 x 34.00 x 5.00mm cavity. The decoded chip communicates with the device exactly like the factory battery. Cyclists restoring a worn unit can swap it in without soldering.

Capacity and voltage must match the original

The single specification that decides compatibility is the 1000mAh capacity paired with 3.7V output in the stated 51.00 x 34.00 x 5.00mm form factor. If your device requires a different milliamp-hour rating, voltage or physical envelope this cell will not work. Verify the part number KE37BE49D0DX3 on your old pack before ordering.

Low heat and stable draw in normal rides

In typical GPS navigation use the pack runs cool and draws steady current without audible noise. The integrated protection circuit guards against overcharge, over-discharge and short circuits, keeping cell temperature well below the 60 °C storage limit. Normal cycling loads do not stress the chemistry, so the unit maintains consistent voltage throughout a ride.
