It replaces part number EB-BR630ABY and fits directly into the earbud housing. When the original cell degrades and the buds no longer hold a usable charge, this restores full capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-R630N and Galaxy Buds 3 Pro compatibility:\u003c\/strong\u003e\n    Both models share the same cell form factor, voltage rail, and BMS handshake protocol — 30.70 x 21.00 x 5.50mm footprint with a 3.88V nominal charge curve matched to Samsung's charging IC.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through Samsung's charge controller and confirmed the BMS accepted the handshake without fault codes. The protection circuit responded correctly to both charge cutoff at 4.35V and low-voltage cutoff near 3.0V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Place the earbud in the case and allow a complete charge cycle before pairing. The Galaxy Buds Live case logs the new cell during this cycle — skipping it causes the companion app to display an inaccurate battery percentage.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Galaxy Buds Live cuts out mid-call on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Buds Live drives two simultaneous loads — audio playback and the Bluetooth radio. Under a voice call, peak draw spikes above what idle streaming requires. If the replacement cell hasn't completed a full charge cycle, the BMS can interpret the brief voltage sag from that combined draw as an undervoltage event and cut power. This is not a faulty battery — it resolves after the first two or three full charge cycles stabilise the cell's internal resistance.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCompanion app showing 0% or incorrect battery level after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's Galaxy Wearable app reads battery state through the BMS, not raw voltage. After a cell swap, the BMS ships at storage voltage — roughly 3.6–3.7V — and the app cannot map that to an accurate percentage until the cell completes a calibration cycle. Place both earbuds in the case, close the lid, and let the case charge them to 100% without interruption. After that cycle, the app percentage will track correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428098113626,"sku":"BWCS-SMR630SH-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428098146394,"sku":"BWCS-SMR630SH-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428098179162,"sku":"BWCS-SMR630SH-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMR630SH-1.webp?v=1779934087","url":"https:\/\/batteryweb.com\/products\/samsung-sm-r630n-replacement-battery-388v-500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
