It slots into devices where the original cell has degraded, lost capacity, or stopped holding a charge. Dimensions are 79.25 × 63.94 × 5.06mm — confirm your existing cell matches before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP7000 and Precious P7000 compatibility:\u003c\/strong\u003e\n    Both variants use the same physical cell format, voltage rail, and connector pinout. The BMS on each device communicates with the cell over the same interface, so one replacement cell covers both models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the P7000 platform and confirmed BMS handshake, charge acceptance across all stages, and stable voltage delivery under screen-on and modem load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, disable fast charging and run one complete discharge down to automatic shutdown, then charge to 100% uninterrupted. This gives the fuel gauge IC a full reference sweep against the new cell's discharge curve before any high-current charging pushes current into an uncalibrated state.\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 Elephone P7000 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem, not a capacity problem. Under modem transmission or screen-on load, the new cell's voltage drops faster than the fuel gauge IC predicts, because the IC is still using the discharge curve from the old degraded cell. When cell voltage dips below the BMS cutoff threshold — typically around 3.2V — the phone shuts off even though the percentage display still reads 20–30%. One full discharge-to-shutdown and uninterrupted charge cycle resets the coulomb counter and re-maps the gauge to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage, and if a replacement cell drops below approximately 2.5V per cell, the BMS locks out to prevent damage — the phone will not power on at all. Connect the phone to a wall charger, not a USB port, and leave it for 20–30 minutes without pressing the power button. The charge IC needs time to trickle current into the locked-out cell and bring it above the BMS re-initialisation threshold, usually around 2.8–3.0V, before normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392046923866,"sku":"BWCS-ELP700SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392046956634,"sku":"BWCS-ELP700SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392046989402,"sku":"BWCS-ELP700SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ELP700SL-1.webp?v=1779143125","url":"https:\/\/batteryweb.com\/products\/elephone-p7000-replacement-battery-38v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
