2200 mAh Replacement Battery

This 7.4 V lithium-ion cell delivers 2200 mAh and 16.28 Wh of capacity for compatible Garmin GPSMAP aviation and marine units. It fits the 276, 276c, 296, 376, 376c, 378, 396, 478, 495 and 496 models without modification. The pack is manufactured to match the original OEM specifications for voltage and form factor. No memory effect means the battery can be topped up at any time without reducing usable capacity.

Replaces OEM Part Numbers

The unit substitutes Garmin part numbers 010-10517-00, 010-10517-01 and 011-00955-00 directly. Install it when the original cell no longer holds a charge through a typical flight or voyage. The jump is worth it when run-time has dropped below operational minimums and a reliable power source is required for navigation continuity. One-year replacement coverage backs the swap.

Suits Pilots and Mariners

Owners of the listed GPSMAP models who need a fresh power cell for extended trips will find this a direct fit. Buyers whose device is not in the compatibility list should look elsewhere, as the connector and voltage are specific to these units. Users requiring a higher capacity than 2200 mAh will not be served by this pack. Anyone needing a different voltage or chemistry must source an alternative.

Questions about this item

Does the 7.4V 2200mAh battery match the original Garmin 010-10517-00 form factor for the GPSMAP 276c?

Yes, it is manufactured to the exact same specifications as the OEM Garmin battery and replaces part numbers 010-10517-00, 010-10517-01 and 011-00955-00, so it fits the GPSMAP 276, 276c, 296, 376, 376c, 378, 396, 478, 495 and 496.

How is the battery installed in the GPSMAP 396, and what step is often missed?

Open the battery compartment, remove the old pack, insert the new 7.4V 2200mAh unit with the connector oriented the same way, and fully seat the latch; the step users miss is not charging the new lithium-ion pack for a full cycle before first use.

When will the 16.28Wh lithium-ion cell need replacement in a GPSMAP 496?

Lithium-ion cells have no memory effect and can be charged or discharged as needed; typical service life is several hundred full cycles before capacity drops enough to warrant a new battery.
