It replaces OEM part EB-BG973ABU and GH82-18826A. The battery restores full power to the display, processor, modem, and all onboard functions.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-G973 series compatibility:\u003c\/strong\u003e\n    All SM-G973 variants share the same 3.85V power rail, connector pinout, and BMS handshake protocol. The cell dimensions — 82.40 × 43.53 × 5.10mm — match the original chassis footprint exactly, so no mechanical modifications are needed during installation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an SM-G973F through a full charge-discharge cycle. The BMS accepted charge at both standard and fast-charge rates. Voltage at rest settled at 3.85V. Coulomb counter communication with the OS came up clean with no fault flags on the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge recalibration:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC build an accurate discharge curve against the new cell before high-current charging pushes current into an uncalibrated state. One full slow cycle prevents erratic percentage readings early on.\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 replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is the most reported issue after a cell swap on the S10. The fuel gauge IC is still using the discharge curve it mapped to the old, degraded cell. When the new cell hits a voltage point that the IC associates with a low-battery cliff, it signals a shutdown even though usable charge remains. Under modem or screen load, the voltage sag on a fresh cell can look different from what the gauge expects. One complete slow discharge to below 5% followed by a full charge to 100% re-anchors the coulomb counter to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not activating on the first cycle after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a cell replacement, the S10's charge IC sometimes does not negotiate the fast-charge handshake on the very first plug-in. This happens because the BMS on the new cell starts in a conservative current-limited state until it completes one full cycle and confirms thermal and voltage parameters are stable. Plug in using a standard 5V charger for the first full charge rather than a fast-charge adapter. After that first cycle completes, fast charging negotiation re-enables normally and the device will accept the higher current rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392009240666,"sku":"BWCS-SMG937XL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392009273434,"sku":"BWCS-SMG937XL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392009306202,"sku":"BWCS-SMG937XL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMG937XL-1.webp?v=1779142920","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-s10-replacement-battery-385v-3300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
