It fits the Pulse 15 directly and restores full portable computing capacity when the original cell has degraded or failed. Voltage and physical dimensions match OEM spec: 287.60 × 97.30 × 9.50mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePulse 15 fitment:\u003c\/strong\u003e\n    The Pulse 15 uses a three-cell Li-Polymer pack at a nominal 11.55V rail. This replacement matches that voltage and connector configuration, so the embedded controller recognises the cell and allows charging without a BMS handshake fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, discharge, and load spikes typical of a developer workload — sustained CPU compile plus display at full brightness. The BMS held within spec and did not trigger a protection cutoff under those conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the Pulse 15:\u003c\/strong\u003e\n    After fitting, run the laptop down to hibernate cutoff on battery alone, then charge uninterrupted to 100% without interruption. This forces the Pulse 15's fuel gauge IC to re-learn the new cell's actual capacity and clears the false \"poor health\" flag that the BIOS logs 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\"\u003eBIOS reporting battery health as poor after fitting the replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pulse 15 BIOS reads health data stored in the battery's EEPROM and compares it against accumulated cycle history from the old cell. A new cell carries fresh EEPROM values that don't match the BIOS's learned profile, so it flags the battery as degraded or unknown immediately after installation. This is a calibration mismatch, not a fault with the cell itself. One full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle and clears the warning on the next boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% remaining shown on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't yet mapped the new cell's voltage curve. Under full CPU plus display load, the cell voltage drops faster than the uncalibrated gauge expects, and the system hits its low-voltage shutdown threshold while the display still shows 20–30% charge remaining. It is not a defective cell — it is an uncalibrated gauge reading the wrong point on the discharge curve. Run two full discharge-to-hibernate and charge-to-100% cycles; after that the gauge aligns with actual cell voltage and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409522458714,"sku":"BWCS-MDX250NB-1","price":122.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409522491482,"sku":"BWCS-MDX250NB-2","price":141.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409522524250,"sku":"BWCS-MDX250NB-3","price":154.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDX250NB-1.webp?v=1779579941","url":"https:\/\/batteryweb.com\/products\/tuxedo-pulse-15-replacement-battery-1155v-7800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
