It replaces OEM part numbers SSB-P28LS9, SSB-V20CLS\/E, SSB-P28LS6\/E, SSB-P28LS6, and SSB-V20KLS. Fits directly into the original battery bay with no modifications.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP28 series compatibility:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell voltage rail, physical connector pinout, and BMS handshake protocol — which is why one cell covers the full P28 lineup despite the varied model suffixes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and load cycles on P28-series hardware. The BMS held voltage within spec across the discharge curve, and the protection circuit tripped correctly at low-cell threshold before reaching damaging depth.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset after install:\u003c\/strong\u003e\n    After fitting this cell, run a full discharge to hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears after every cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Samsung P28's BIOS reads health data from EEPROM registers on the battery's fuel gauge IC — not from live voltage. When a new cell is installed, those registers still carry the degradation profile of the old pack. The BIOS sees this stale data and flags health as poor or unknown before any real measurement occurs. Running one full discharge-to-cutoff cycle followed by an uninterrupted charge to 100% rewrites the fuel gauge's learned capacity registers. After one or two calibration cycles, the health reading normalises to reflect the new cell's actual condition.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on meter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't yet calibrated against the new cell's discharge curve. The gauge underestimates remaining capacity and reports a higher percentage than the cell can actually sustain under combined CPU and display load. When the cell voltage drops below the BMS cutoff threshold — typically around 9.0–9.3V for an 11.1V three-cell pack — the system shuts down even though the OS still shows charge remaining. Run two full discharge-to-hibernate cycles charged back to 100% each time to let the fuel gauge IC re-anchor its curve to the new cell's actual voltage profile.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410832588890,"sku":"BWCS-SSP28NB-1","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410832621658,"sku":"BWCS-SSP28NB-2","price":139.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410832654426,"sku":"BWCS-SSP28NB-3","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SSP28NB-1.webp?v=1779581287","url":"https:\/\/batteryweb.com\/products\/samsung-p28-xvm-735-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
