Cameron Sino 1250mAh 4.63Wh Replace Battery for Garmin Edge 605 705 PN 361-00019-12

Direct Replacement for Edge 605 and 705

This Cameron Sino battery is a lithium-polymer pack rated at 1250 mAh and 4.63 Wh with a nominal voltage of 3.7 V. It matches the original Garmin part number 361-00019-12 and fits the Edge 605, Edge 705 and Nuvi 465 GPS navigators. The pack measures 59.81 x 36.25 x 5.77 mm and weighs 23.1 g. A decoded chip allows it to communicate with the device exactly like the factory cell.

Single-Cell Lithium-Polymer Limits

Lithium-polymer chemistry delivers 3.7 V from one pouch cell, so capacity is fixed at 1250 mAh and cannot be expanded by paralleling cells inside the device. The pack has built-in protection against over-charge, over-discharge, over-voltage and short-circuit, but it still relies on the GPS unit's own charge controller for correct termination voltages. Running the battery below its safe voltage or charging with an unregulated adapter can permanently reduce cycle life.

Verify Model Number and Connector

Before ordering, confirm that your device is an Edge 605, Edge 705 or Nuvi 465 and that the original battery carries part number 361-00019-12. Check that the connector on your existing pack matches the replacement; an incorrect fit will prevent the decoded chip from communicating. Plan for two or three full charge and discharge cycles to reach rated capacity, and avoid chargers that are not approved for the Garmin unit.
