It powers the display, heart rate sensor, GPS, and fitness tracking functions. Replace it when the original cell no longer holds a charge or the watch fails to power on.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGear Fit 2 Pro \/ SM-R365 fitment:\u003c\/strong\u003e\n    Both part numbers (EB-BR365ABE and GH43-04770A) refer to the same Samsung-spec cell. The SM-R365 uses a 3.85V nominal rail with a flat Li-Polymer form factor measuring 30.00 × 15.50 × 6.00mm — the connector and BMS handshake match this cell directly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the SM-R365 charge circuit and confirmed the BMS accepted the cell without error flags. Charge current tapered correctly at full capacity, and the fuel gauge IC registered a valid state-of-charge reading after one complete cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap charge routine for the SM-R365:\u003c\/strong\u003e\n    Place the watch on its magnetic charger immediately after fitting this cell and charge it to 100% before first use. The fuel gauge IC on this platform loses its reference point when the cell is removed — it cannot recalibrate without a full charge cycle starting from near-zero.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWatch showing 0% immediately after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SM-R365 uses a coulomb-counting fuel gauge IC that tracks charge state relative to a stored reference. When the cell is removed, that reference resets to zero. The watch reads 0% not because the new cell is flat, but because the IC has no baseline to work from. Put the watch straight on the charger and let it run to 100% — once the IC completes that first full cycle, percentage readings return to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeart rate sensor running the new cell flat in under a day\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eContinuous heart rate monitoring on the Gear Fit 2 Pro keeps the optical sensor active at all times, which accounts for a significant share of total draw on a 200mAh cell. If the watch is also set to always-on display, combined draw can exhaust the cell well before the expected multi-day window. Switch heart rate monitoring to \"every 10 minutes\" in the Samsung Health app and disable always-on display — these two changes are the single biggest factor in extending charge intervals on this platform.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416164008026,"sku":"BWCS-SMR365SH-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416164040794,"sku":"BWCS-SMR365SH-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416164073562,"sku":"BWCS-SMR365SH-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMR365SH-1.webp?v=1779760523","url":"https:\/\/batteryweb.com\/products\/samsung-gear-fit-2-pro-replacement-battery-385v-200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
