Replacement Battery for GPSMAP 276Cx

This lithium-ion pack replaces the original Garmin 010-12456-06 and 361-00092-00 cells in the GPSMAP 276Cx navigator. It is built for owners who need a fresh power source for marine or outdoor navigation without changing devices. The 5200mAh capacity at 3.7V matches the factory energy rating of 19.24Wh. Installation follows the same connector layout as the stock unit.

Sustained runtime on the water

The 5200mAh cell delivers consistent voltage through long days of chart plotting and sonar use rather than fading after a short burst. A fully decoded chip communicates with the GPSMAP 276Cx power management so the fuel gauge remains accurate over repeated cycles. Overcharge, over-discharge and short-circuit protection circuits guard the pack during continuous operation. Expect stable output until the navigator signals a recharge.

Capacity that matches the original spec

The decisive figure is 5200mAh at 3.7V, which equals the 19.24Wh the GPSMAP 276Cx was designed around. Buyers who need more storage than a single pack provides should carry a spare rather than seek a higher-capacity cell that does not exist for this form factor. Dimensions of 74.70 x 42.70 x 21.75mm and 107.8g weight ensure the battery bay closes flush. No other specification overrides this capacity match.

Questions about this item

Does the 3.7 V lithium-ion cell run warm or draw noticeable power during all-day GPS use?

The pack is a direct 3.7 V 5200 mAh lithium-ion replacement; it generates no more heat than the original battery and consumes only the power the GPSMAP 276Cx requests.

Must I already own a specific Garmin charger or docking cradle for this battery to charge?

The battery charges inside the GPSMAP 276Cx using the unit's standard power adapter or USB cable; no separate charger or cradle is required.

Will the 74.70 × 42.70 × 21.75 mm pack fit the battery compartment of my older GPSMAP 276Cx without modification?

Yes, the dimensions match the original Garmin 010-12456-06 and 361-00092-00 cells, so it seats securely in the existing compartment.
