Compatible GPSMAP 276Cx battery

The Cameron Sino DS-CS-GMC276SL is a lithium-ion replacement cell built for the Garmin GPSMAP 276Cx. It matches the original part numbers 010-12456-06 and 361-00092-00. The pack delivers 5200mAh at 3.7V for 19.24Wh of energy. It ships new in black with dimensions of 74.70 x 42.70 x 21.75 mm.

Sustained navigation runtime

The 5.2Ah capacity supports extended operation during long trips without frequent recharging. Lithium-ion chemistry provides stable voltage output across the discharge cycle. The cell maintains consistent power delivery for continuous GPS tracking and display use. No memory effect means partial charges do not reduce usable capacity over time.

Proprietary form-factor limits

The specific physical size and connector layout restrict use to the GPSMAP 276Cx unit only. It cannot serve as a generic power bank for other devices. Replacement requires opening the device compartment designed for this exact battery shape. Compatibility is limited to the listed Garmin model and part numbers.

Questions about this item

Will the 5200 mAh battery get hot during a full day of GPS use?

The Li-ion pack is rated at 3.7 V and 19.24 Wh, so normal navigation loads produce only modest warmth.

Does the DS-CS-GMC276SL fit my Garmin GPSMAP 276Cx without extra parts?

It replaces Garmin part numbers 010-12456-06 and 361-00092-00, matching the 74.70 x 42.70 x 21.75 mm bay exactly.

Can I keep using my older Garmin charger with this 5.2 Ah replacement?

Yes, the cell chemistry and voltage are identical to the original 276Cx battery, so the existing charger works unchanged.
