Replacement Battery for Gear S2 Series

This 250mAh lithium-polymer cell replaces the original EB-BR720ABE battery in Gear S2, Gear S2 Classic, R7200, R720X, R732, SM-R720 and SM-R732 smartwatches. It delivers 0.93Wh at 3.7 volts and fits the 25.50 x 24.50 x 4.60mm compartment. A fully decoded chip ensures the watch recognises the cell exactly like the factory unit.

Thermal Behaviour and Power Draw

The slim 4.0g pouch runs at the standard 3.7V nominal voltage, so heat output during normal wear stays low and the watch remains comfortable on the wrist. Internal over-charge, over-discharge, over-voltage and short-circuit protection circuits prevent abnormal temperature rise. No active cooling is required and the cell adds no audible noise to the device.

Build Quality and Daily Fit

The pack measures 25.50 x 24.50 x 4.60mm and weighs 4.0g, matching the original dimensions for a flush fit behind the watch back. Shock-absorbing foam in the retail package protects the cell during transit. Installation videos are widely available online, though buyers who want a solder-free connector or a larger capacity cell will need a different solution.

Questions about this item

How do I install this battery in my Gear S2 and what step do people often miss?

Open the watch case, disconnect the old battery connector, fit the 25.50 x 24.50 x 4.60 mm cell, then reconnect the new connector firmly; the step most people miss is ensuring the connector clicks fully into place.

What maintenance will this 250 mAh lithium polymer cell need over its life?

No scheduled maintenance is required; after the first 2 or 3 full charge and discharge cycles the battery reaches its best capacity, then simply avoid low-quality chargers and temperatures above 60 °C.

What limit appears first during sustained use of this 3.7 V smartwatch battery?

The 0.93 Wh capacity sets the runtime ceiling; under continuous load the watch will hit the low-voltage cutoff after roughly one day, so plan a daily recharge.
