It fits the RZ09-01161R32 and Blade 14 INCH (512GB) variants using the same connector and BMS interface. Install it when the original cell no longer holds voltage under load or fails to register in the BIOS.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade 14 2014–2015 compatibility:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell Li-Polymer architecture, connector pinout, and BMS communication protocol — so one cell fits both years without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a Blade 14 unit. The BMS handshake completed correctly, charge current stepped down at the expected cutoff threshold, and the fuel gauge IC accepted the new cell data.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap discharge cycle on the Blade 14:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.\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 after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Blade 14 BIOS reads health data from EEPROM registers carried over from the old cell. When a new cell arrives, those registers still hold degraded values from the previous pack. The BIOS compares measured capacity against the stored rated value and flags poor health even though the new cell is at full capacity. One complete learn cycle — full discharge to hibernate, then a full uninterrupted charge — rewrites those registers and clears the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% shown on the gauge after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The gauge misreads the voltage cliff — where cell voltage drops steeply under combined CPU and display load — and triggers a shutdown while the display still shows charge remaining. It is not a fault with the replacement cell. Run two full discharge-to-hibernate and full-recharge cycles, and the gauge recalibrates; shutdowns stop once the IC maps the correct low-voltage cutoff point, typically around 9.9V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409691246682,"sku":"BWCS-RZB141NB-1","price":131.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409691279450,"sku":"BWCS-RZB141NB-2","price":152.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409691312218,"sku":"BWCS-RZB141NB-3","price":167.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RZB141NB-1.webp?v=1779580474","url":"https:\/\/batteryweb.com\/products\/razer-blade-14-2015-replacement-battery-111v-6300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
