It replaces OEM part numbers AB503442CA and AB503442BABSTD. Fit the battery, reassemble, and power on — no tools beyond a fingernail or spudger needed for most SCH-R510 back covers.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-R510 cell fit:\u003c\/strong\u003e\n    The SCH-R510 uses a single-cell 3.7V Li-ion pack with a three-pin connector carrying power, ground, and a thermistor line. The BMS reads that thermistor to gate charging current — any replacement must match the original cell dimensions and connector pinout exactly, which AB503442CA does.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the SCH-R510 platform. The BMS accepted the cell on first connection, charge termination triggered correctly at 4.2V, and the protection circuit tripped as expected at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    On first use, disable fast charging if your carrier version supports it, then run one full discharge-to-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's actual discharge curve before it starts reporting accurate percentages.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SCH-R510 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SCH-R510 uses a fuel gauge IC that builds a model of the installed cell's discharge curve over time. When you install a new cell, that stored model no longer matches the physical cell — so the reported percentage drifts from the actual state of charge. The fix is one full discharge from 100% down to auto-shutdown, followed by an uninterrupted charge back to 100%. After that single cycle the coulomb counter resets against real data from the new cell, and percentage accuracy stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's discharge curve, which typically had a steeper voltage drop near end of charge. The new cell hits a voltage threshold the IC interprets as critically low, and the phone shuts down before the gauge catches up. It is not a faulty battery — it is a calibration lag. Run two full discharge-charge cycles and the shutdowns should stop. If they persist past two cycles, check that resting cell voltage is above 3.6V with a multimeter; anything below 3.4V at rest signals a deeper cell issue.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405122273370,"sku":"BWCS-SMR510XL-1","price":33.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405122306138,"sku":"BWCS-SMR510XL-2","price":37.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405122338906,"sku":"BWCS-SMR510XL-3","price":40.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMR510XL-1.webp?v=1779370243","url":"https:\/\/batteryweb.com\/products\/samsung-sch-r510-replacement-battery-37v-1300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
