Sustained Use Behaviour

Rated at 3.7 volts and 0.93Wh, the cell delivers its capacity over normal daily cycles. A new battery reaches best performance after two or three full charge and discharge cycles. Integrated protection guards against overcharge, over-discharge, over-voltage and short circuit during extended operation.

Pre-Order Checks

Verify the exact model number on your watch and the part number printed on the original battery before ordering. Confirm the connector layout matches the 25.62 x 21.02 x 5.82mm dimensions. Avoid low-quality third-party chargers, which can shorten service life.

Questions about this item

How much heat does the 3.7 V, 250 mAh battery generate during all-day use?

The replacement cell runs at the same 3.7 V and 250 mAh rating as the original, so thermal output matches the factory specification for the Gear 2 and Gear 2 Neo.

What tools or parts must I already have to install this battery in my SM-R380?

You need a small Phillips screwdriver and a plastic pry tool to open the watch case and disconnect the original connector before fitting the new cell.

Will the decoded chip in this pack work with the original charging cradle for the Gear 2 Neo?

Yes, the fully decoded chip communicates identically to the Samsung B1230J1EA and EB-BR380FBE packs, so the standard cradle charges it normally.
