It fits the Huawei Watch 5, Watch 5X, and Watch 5X Pro smartwatches. Dimensions are 31.60 × 28.00 × 6.60mm — confirm these against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWatch 5 series compatibility:\u003c\/strong\u003e\n    The Watch 5, Watch 5X, and Watch 5X Pro share the same battery bay geometry, connector pin-out, and BMS handshake protocol. All three accept HB652933EGW 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 Watch 5 platform. The BMS accepted the cell without error flags, fuel gauge recalibrated correctly after a full charge cycle, and health sensors remained active throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap charge cycle:\u003c\/strong\u003e\n    After fitting this cell, place the watch on its magnetic charger immediately and bring it to 100% before first use. The fuel gauge IC loses its reference point during a cell swap. Without a full charge from near-zero, the percentage display will read inaccurately for days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy continuous heart rate monitoring shortens charge intervals on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Watch 5 series uses a multi-wavelength optical sensor for continuous HR tracking. On a new cell, internal impedance is slightly higher than a broken-in cell, so the sensor draws a marginally larger current to maintain signal quality. This effect typically flattens out after five to seven full charge cycles as the cell's internal resistance drops. During that break-in window, charge intervals may be shorter than expected — this is normal and not a fault with the replacement cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWatch not pairing to phone after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery cuts power to the BLE stack entirely, which terminates the active session stored on both the watch and the paired phone. When the watch restarts, it generates a new session key that the phone does not recognise. Open the Huawei Health app, navigate to device settings, remove the existing watch entry, and re-pair from scratch. The watch should appear in the device list within 30 seconds of initiating a fresh pairing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416154046554,"sku":"BWCS-HUX510SH-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416154079322,"sku":"BWCS-HUX510SH-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416154112090,"sku":"BWCS-HUX510SH-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUX510SH-1.webp?v=1779760505","url":"https:\/\/batteryweb.com\/products\/huawei-watch-5-replacement-battery-388v-780mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
