It matches the original cell's dimensions at 83.90 × 63.26 × 4.20mm and connects via the factory flex connector. Capacity matches the stock specification at 15.79Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEnjoy 20 Plus and 5G Standard Edition fit:\u003c\/strong\u003e\n    Both variants — FRL-AN00a and the Changxiang 20 Plus — use the same battery bay dimensions, connector pinout, and BMS handshake. One cell covers the full model range listed above.\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 Enjoy 20 Plus platform. The BMS accepted the cell without a protection-circuit lockout, and the charge IC completed a full CC\/CV cycle to 4.35V termination voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first installation:\u003c\/strong\u003e\n    On first use after fitting, disable fast charging and run one complete discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before the coulomb counter commits to its reference baseline.\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 Enjoy 20 Plus after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell has a slightly different voltage-versus-capacity curve than the degraded cell it replaces. The fuel gauge IC still holds calibration data from the old cell, so when the new cell hits a voltage the IC doesn't expect at that state of charge, the system treats it as a critical low-battery event and cuts power. This isn't a fault with the replacement cell — it's the coulomb counter working off the wrong reference curve. Run two full discharge-to-charge cycles at standard charge rate to allow the IC to relearn the curve. After recalibration, shutdowns below 20% should stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charging not activating on the first cycle after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHuawei's proprietary fast charge protocol (FCP) involves a handshake between the charge IC and the battery's BMS before elevated current is permitted. On the very first cycle with a new cell, the BMS may hold the charge IC in standard 5V\/1A mode until it confirms cell impedance is within expected parameters. Plug in using the original Huawei charger and cable — third-party USB-PD adapters can stall this handshake entirely. If fast charging still doesn't activate after one full standard-rate cycle, check that the charger output shows 9V or above in the phone's battery settings under charging status.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391880822874,"sku":"BWCS-HUE200SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391880855642,"sku":"BWCS-HUE200SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391880888410,"sku":"BWCS-HUE200SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUE200SL-1.webp?v=1779142479","url":"https:\/\/batteryweb.com\/products\/huawei-enjoy-20-plus-replacement-battery-385v-4100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
