It fits the RTX 2080 Max-Q, RTX 2060, and 2019–2020 Blade Pro 17 models sharing the RC30-0287 connector and BMS handshake. Install it when the original cell no longer holds charge or the OS reports critically degraded health.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade Pro 17 series fit:\u003c\/strong\u003e\n    The 2019, 2020, RTX 2060, and RTX 2080 Max-Q variants all run the same 15.4V four-cell pack with an identical ZIF connector and BMS communication protocol — that shared electrical spec is why one cell covers all these SKUs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge, full discharge, and a second charge cycle on a Blade Pro 17 chassis. The BMS negotiated correctly, charge current stepped down at 95% as expected, and cutoff triggered cleanly at low voltage without triggering an emergency shutdown.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on Blade Pro 17:\u003c\/strong\u003e\n    After fitting this cell, run the laptop on battery until it hibernates at the BIOS low-voltage cutoff, then charge uninterrupted to 100%. This resets the fuel gauge IC's learn cycle against the new cell and clears the inaccurate health warning that appears in Razer Synapse and Windows 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 Blade Pro 17 shuts down at 20–30% battery remaining after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Blade Pro 17's fuel gauge IC stores discharge curve data from the old cell in memory. When a new cell is installed, the IC maps voltage readings against the old curve — which no longer matches. Under full CPU and GPU load, the 15.4V pack voltage sags faster than the stale curve predicts, and the laptop interprets a midrange state-of-charge as a critical low-voltage event. Running two full calibration cycles retrains the IC against the actual discharge curve of the replacement cell and stops the premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting the new battery as 0% or \"unknown\" immediately after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the EEPROM data embedded in the old battery — cycle count, rated Wh, and health flags — no longer exists for the new cell until a charge cycle writes fresh data. The Razer BIOS reads these values on boot; a missing or blank EEPROM response returns a null state. Connect AC power, allow a full uninterrupted charge to 100%, then reboot. The BIOS will read the new cell's EEPROM correctly and display an accurate state of charge, typically resolving at 15.4V full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409569677402,"sku":"BWCS-RZB172NB-1","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409569710170,"sku":"BWCS-RZB172NB-2","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409569742938,"sku":"BWCS-RZB172NB-3","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RZB172NB-1.webp?v=1779580092","url":"https:\/\/batteryweb.com\/products\/razer-blade-pro-17-rtx-2080-max-q-replacement-battery-154v-4500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
