It fits the RZ09-01663E53-R3G1, RZ09-01662E54-R3U1, and Pro 4K variants that share the same cell footprint and connector pinout. Swap it in when the original cell no longer holds charge or the laptop won't run unplugged.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade F1 and Pro 4K platform fit:\u003c\/strong\u003e\n    These models share the same 11.4V three-cell series configuration, connector housing, and BMS communication line. The cell dimensions — 359.50 × 78.72 × 13.60mm — match the chassis bay without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Blade F1 unit. The BMS handshake completed on first connect, charge current stepped down correctly at 80% and 95%, and the protection circuit tripped cleanly at low-voltage cutoff without hard shutdown.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap BIOS recalibration on the Blade F1:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. The Blade F1 BIOS stores cycle data from the old cell in firmware — skipping this step leaves the health indicator reporting inaccurate figures for weeks.\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 F1 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnder full CPU and display load, the Blade F1 draws significantly more current than at idle. A new cell that hasn't been calibrated hits a voltage cliff — where cell voltage drops faster than the fuel gauge IC can track — and the BMS reads an undervoltage condition before the displayed percentage reaches zero. This is a calibration gap, not a faulty cell. Run two full discharge-to-cutoff cycles and the fuel gauge IC will map the new cell's discharge curve accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS showing battery health as \"poor\" or \"unknown\" immediately after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Razer Blade F1 BIOS reads health data from EEPROM registers carried over from the previous cell — it doesn't reset that data when a new battery connects. The system flags a mismatch between the stored cycle count and the new cell's reported state. This clears after the BIOS completes one full battery learn cycle: discharge fully until the laptop hibernates, then charge to 100% without interruption. After that cycle, the health status reports correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409702649946,"sku":"BWCS-RBF100NB-1","price":139.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409702682714,"sku":"BWCS-RBF100NB-2","price":160.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409702715482,"sku":"BWCS-RBF100NB-3","price":176.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RBF100NB-1.webp?v=1779580516","url":"https:\/\/batteryweb.com\/products\/razer-blade-f1-replacement-battery-114v-8600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
