About this replacement
Samsung Gear Live / SM-R382 — 3.7V Li-Polymer Replacement Battery (EB-BR382FBE)
This is a 3.7V, 220mAh lithium-polymer cell for the Samsung Gear Live smartwatch (SM-R382). It replaces the original EB-BR382FBE when capacity has faded or the battery no longer holds a charge. The Gear Live is an Android Wear device — it runs continuous heart rate monitoring, Bluetooth, and notification display from this single small cell.
- Gear Live / SM-R382 fitment: Both the Gear Live and its SM-R382 designation share the same battery bay, connector pin layout, and BMS handshake. One cell covers both references.
- Bench tested on actual hardware: We ran the EB-BR382FBE replacement on a Gear Live unit and confirmed the BMS accepted the cell without fault flags. The fuel gauge IC initialised correctly after a full charge cycle from near-zero.
- Fuel gauge calibration after swap: After fitting this cell, place the watch on its magnetic charger immediately and charge to 100% before first use. The Gear Live's fuel gauge IC loses its reference point when the original cell is removed. Without a full charge cycle from near-zero, the watch will report inaccurate state-of-charge readings.
Why the Gear Live charge contacts stop making connection after reassembly
The Gear Live uses a magnetic pogo-pin charger that aligns to two small contact pads on the watch underside. If the rear cover shifts even slightly during reassembly, those pads move out of the charger's magnetic pull zone. The watch will sit on the cradle and look like it's charging but the LED will not light and voltage will not rise. Re-seat the rear cover and press firmly at each corner before testing the charge connection again.
Watch shows 0% and will not power on immediately after battery swap
This is a fuel gauge IC issue, not a cell fault. When the original battery is removed, the MAX17048 or equivalent gauge chip on the Gear Live loses its learned reference and defaults to an unknown — often 0% — state. The watch may refuse to boot until voltage climbs above its startup threshold. Place it on the charger for at least 15–20 minutes until the battery reaches approximately 3.85V, then press and hold the power button.
