It replaces OEM part numbers including EB504465VU, EB504465VK, and EB504465LA. If the original cell no longer holds charge through a normal day of calls, messaging, and app use, this cell swaps in directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-R940 platform compatibility:\u003c\/strong\u003e\n    The SCH-R940, Conquer 4G, and Tikal variants share the same connector pinout, BMS handshake protocol, and 3.7V nominal rail. A single cell covers all of them without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the SCH-R940 charge IC and confirmed the BMS handshake completed correctly on first insertion. The protection circuit responded to both overvoltage and undervoltage cutoff at expected thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after cell swap:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle. This gives the fuel gauge IC time to map its coulomb counter against the new cell's actual discharge curve before any high-current charge session begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the SCH-R940 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SCH-R940's fuel gauge IC stores a learned discharge curve from the old cell. When a new cell goes in, that learned curve no longer matches reality. The phone thinks 20–30% remains, but the new cell's actual voltage under modem or screen load drops below the shutdown threshold faster than the IC predicts. The fix is one full discharge to near 0% followed by an uninterrupted charge to 100%. After that cycle, the coulomb counter resets against the new cell and percentage readings stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery compartment on the first charge after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA brand-new cell has higher internal impedance than a broken-in one. On the first charge cycle, the charge IC pushes current into that higher-impedance cell, which converts more energy to heat than normal. This is expected behaviour and not a fault. Warmth — not heat — during the first one or two cycles is normal. If the back panel becomes hot enough to be uncomfortable after the second full charge, check that the replacement part number matches EB504465VU exactly, as a mis-matched cell can present an incorrect impedance profile to the charge IC.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405028425818,"sku":"BWCS-SMI8320SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405028458586,"sku":"BWCS-SMI8320SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405028491354,"sku":"BWCS-SMI8320SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI8320SL-1.webp?v=1779369859","url":"https:\/\/batteryweb.com\/products\/samsung-sch-r940-replacement-battery-37v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
