It replaces the original battery when the cell has degraded, lost capacity, or stopped holding a charge. Dimensions are 65.30 × 38.74 × 5.70mm — measure your bay before ordering if you are unsure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eET960 fitment:\u003c\/strong\u003e\n    The BP07 part number is specific to the ET960 platform. The connector pinout and BMS handshake match the charge IC on this board — swapping in a generic cell with a mismatched BMS profile can cause the OS to misread state-of-charge from the first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full discharge and charge on the ET960 platform. The BMS accepted the cell without triggering a fault flag, and the fuel gauge IC began tracking voltage within the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the ET960 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new lithium-polymer cell has a slightly different discharge curve than the original cell the fuel gauge IC was calibrated against. When the phone hits a voltage point the IC interprets as empty — even if the cell still has charge — the modem or display load causes a voltage dip below the shutdown threshold. The OS reads this as 0% and cuts power instantly. Running two full discharge-charge cycles at standard rate recalibrates the coulomb counter and eliminates most of these early shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eET960 not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-polymer cells self-discharge in storage. If the BP07 dropped below approximately 2.5V per cell before installation, the BMS enters a lockout state and the phone will not respond to a normal power button press. Connect the phone to a charger and leave it for 20–30 minutes without pressing anything — the charge IC trickle-charges the cell back above the BMS unlock threshold. Once the voltage recovers above 3.0V, the BMS releases and the phone will power on normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405144916058,"sku":"BWCS-ET960SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405144948826,"sku":"BWCS-ET960SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405144981594,"sku":"BWCS-ET960SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ET960SL-1.webp?v=1779370263","url":"https:\/\/batteryweb.com\/products\/lenovo-et960-replacement-battery-37v-1300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
