It slots into the original battery bay and connects to the same BMS handshake points the motherboard expects. Use it when the original cell can no longer hold a usable charge under normal computing load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV87P platform compatibility:\u003c\/strong\u003e\n    The V87P-5480S2N and V87P share the same 14.8V four-cell Li-ion rail, connector pinout, and BMS communication protocol. One replacement cell covers both variants without any hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, full-load discharge, and idle standby. The BMS held stable across all three states, with no unexpected cutoff under combined CPU and display draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the V87P:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge down to hibernate-cutoff, then charge uninterrupted to 100% before using the laptop again. This resets the BIOS battery learn cycle 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\"\u003eWhy the V87P BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe V87P reads battery health data from EEPROM stored on the original cell. When a new cell goes in, the BIOS compares live readings against stale EEPROM values and flags a mismatch as poor health. This is a data residue issue, not a fault with the replacement. Running a complete discharge-to-hibernate followed by a full uninterrupted charge gives the BIOS enough fresh data to recalibrate. After one or two full cycles the health warning clears and the gauge reads accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet mapped the new cell's voltage curve. Under full CPU plus display load, voltage drops faster than the uncalibrated gauge predicts, and the system hits a hard undervoltage cutoff while the display still shows charge remaining. The fix is calibration — discharge the laptop fully to auto-hibernate under real workload, not idle. After two to three full cycles the fuel gauge IC tracks the new cell accurately and the early shutdowns stop. Check battery voltage in your system info after calibration: it should read above 14.0V at the 30% mark.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409749868634,"sku":"BWCS-CLP750NB-1","price":110.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409749901402,"sku":"BWCS-CLP750NB-2","price":125.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409749934170,"sku":"BWCS-CLP750NB-3","price":137.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLP750NB-1.webp?v=1779580646","url":"https:\/\/batteryweb.com\/products\/shinelon-v87p-5480s2n-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
