It restores power to devices where the original cell no longer holds a usable charge. Dimensions are 65.25 × 47.78 × 4.75mm — confirm your tray clearance before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAscend Y210 platform fit:\u003c\/strong\u003e\n    The Y210, Y210C, Y210-0151, and U8685D share the same battery bay geometry and connector pinout, all referencing the HB4W1 part number. No adapter or pin modification is needed across this group.\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 a Y210 unit. The BMS accepted the charge IC handshake correctly, held charge cutoff at 4.2V, and triggered low-voltage protection at 3.0V without false trips.\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-to-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before it reports accurate percentages to the OS.\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 Y210 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity problem. When the modem fires a high-power transmission burst or the screen peaks at full brightness, it pulls current that a freshly installed, uncalibrated cell cannot sustain at that state of charge. Voltage drops sharply below the shutdown threshold — typically 3.2–3.4V under load — and the phone cuts out even though the fuel gauge still reads 20–30%. One full discharge-charge cycle lets the coulomb counter recalibrate against the actual cell curve, and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage, and if the HB4W1 cell drops below approximately 2.5V, the BMS enters deep-discharge lockout to prevent cell damage. A standard charger will not wake it — the phone appears completely dead. Connect the device to a low-current USB source such as a PC port rather than a wall adapter, and leave it for 15–30 minutes. Once the BMS detects enough voltage to release the lockout, the charge IC takes over and normal charging resumes from there.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404331810906,"sku":"BWCS-HUY210XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404331843674,"sku":"BWCS-HUY210XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404331876442,"sku":"BWCS-HUY210XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUY210XL-1.webp?v=1779369761","url":"https:\/\/batteryweb.com\/products\/huawei-ascend-y210-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
