It fits the Ascend P6, P6-U06, P6-C00, and Ascend G6, among others. Dimensions are 97.89 × 40.67 × 3.44mm — match these against your original cell before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAscend P6 and G6 compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS communication protocol, which is why a single cell covers the full range. The fuel gauge IC on each device reads cell voltage and charge state over the same internal interface.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge-discharge cycles on the Ascend P6 platform. The BMS accepted the new cell without triggering overcurrent lockout, and the charge IC stepped through the correct CC\/CV phases.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable any fast-charge mode and run one full discharge-to-charge cycle at standard current. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins.\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 Ascend P6 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still using the discharge curve from the old, degraded cell. When the phone reads 25%, the new cell's actual voltage under modem or display load drops faster than the IC expects. The phone hits its low-voltage cutoff threshold and shuts down before the percentage reaches zero. One full discharge-charge cycle at standard current resets the coulomb counter and corrects the reported percentage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone will not power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge during storage. If the cell voltage drops below roughly 2.5V, the BMS enters a protection lockout and blocks current flow to prevent cell damage. The phone shows nothing when you press the power button — no logo, no charging indicator. Connect to a wall charger and leave it for 15–20 minutes; the charge IC will trickle current into the cell until voltage rises above the BMS re-enable threshold of approximately 2.9V, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404307169370,"sku":"BWCS-HUP600SL-1","price":130.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404307202138,"sku":"BWCS-HUP600SL-2","price":155.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404307234906,"sku":"BWCS-HUP600SL-3","price":174.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUP600SL-1.webp?v=1779369643","url":"https:\/\/batteryweb.com\/products\/huawei-ascend-p6-replacement-battery-38v-2000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
