Replacement battery for Galaxy Watch 4

This Cameron Sino VX-228 battery replaces the original power cell in the Galaxy Watch 4 40 mm and Galaxy Watch 4 Classic 42 mm. It delivers 240 mAh capacity at 3.88 V and fits the listed Samsung part numbers. The cell measures 20.70 x 20.10 x 5.00 mm and weighs 5.0 g. A fully decoded chip ensures communication with the watch functions as intended.

Who this suits and who should look elsewhere

Owners of the compatible Galaxy Watch 4 models who need a fresh battery can use this part. Buyers with other smartwatch models or different case sizes cannot use this battery. Installers without experience opening a sealed watch should seek professional fitting.

Deciding specification — 240 mAh capacity

The 240 mAh capacity at 3.88 V is the single figure that determines whether this cell matches the original specification. Verify the original battery part number EB-BR860ABY, EB-BR880ABE, EB-BR880ABY or GH43-05068A before purchase.

Questions about this item

Does the VX-228 battery package include any installation tools or adhesive strips?

The package contains the 240mAh replacement battery with a fully decoded chip and shock-absorbing foam for transit protection. Installation tools and adhesive strips are not included and must be sourced separately.

How do I confirm whether the VX-228 suits my Galaxy Watch 4 40mm versus the Classic 42mm?

Match your watch model number — SM-R865U, SM-R880, SM-R880N, SM-R885 or their regional variants — and verify the original part number EB-BR860ABY, EB-BR880ABE, EB-BR880ABY or GH43-05068A before ordering.

What runtime can I expect from the 240mAh 3.88V cell once installed in a Galaxy Watch 4?

The 0.93Wh capacity restores the original factory runtime; a new cell reaches its best performance after two or three full charge-and-discharge cycles.
