It fits RZ09-0165 and RZ09-0195 series units and replaces OEM part numbers BETTY4, BETTY4B, and 3ICP4\/56\/101-2 among others. If your Blade 14 no longer holds a charge or the original cell has swollen, this is the direct cell swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRZ09-0165 and RZ09-0195 compatibility:\u003c\/strong\u003e\n    Both chassis use the same 11.4V three-cell Li-Polymer configuration, the same 9-pin battery connector, and the same BMS handshake protocol — so a single cell covers both board revisions without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an RZ09-0165 board. The BMS accepted the new cell immediately, charge current ramped correctly through CC\/CV stages, and no protection fault codes were thrown at the EC level.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on Blade 14:\u003c\/strong\u003e\n    After fitting, run the laptop down until Windows forces hibernation, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after swapping cells 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\"\u003eWhy the Blade 14 BIOS reports poor battery health immediately after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Razer Blade 14 embedded controller reads health data from EEPROM stored on the original cell's fuel gauge IC. When a new cell goes in, that EEPROM data is gone and the EC flags the battery as degraded — even though the new cell is at full capacity. This is a data mismatch, not a hardware fault. Running one complete discharge-to-hibernate then a full uninterrupted charge lets the fuel gauge IC write fresh cycle data, which the BIOS then reads correctly. After two or three full cycles, the health indicator typically returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBlade 14 shutting down at 20–30% charge remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell cannot sustain voltage under combined CPU boost and display load — the terminal voltage drops below the EC's cutoff threshold before the fuel gauge reaches 0%. It is more common after the original cell ages, but can also appear briefly on a new cell before calibration. The fix is to complete the full discharge-to-hibernate calibration cycle described above. After calibration, confirm the shutdown threshold has shifted by checking that the battery reaches at or below 5% before the next forced hibernate event.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409702453338,"sku":"BWCS-RZB140NB-1","price":136.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409702486106,"sku":"BWCS-RZB140NB-2","price":158.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409702518874,"sku":"BWCS-RZB140NB-3","price":173.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RZB140NB-1.webp?v=1779580516","url":"https:\/\/batteryweb.com\/products\/razer-blade-14-replacement-battery-114v-5800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
