It fits the Huawei Honor 2, Honor II, Honor Quad, and U9508 handsets. Swap it when the original cell no longer holds a usable charge or the phone shuts down unexpectedly under load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHonor 2 \/ U9508 platform fit:\u003c\/strong\u003e\n    These variants share the same battery bay dimensions, connector pinout, and BMS handshake. The HB5R1V spec covers all of them — voltage rail and thermistor line are identical across the group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a U9508 unit and monitored BMS behaviour through charge and discharge. The protection circuit tripped correctly at the low-voltage cutoff and resumed charging without error after recovery.\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 full discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter to the new cell's actual discharge curve before high-current charging begins on an uncalibrated cell.\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 Honor 2 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity problem. Under peak load — modem activity, screen at full brightness — the new cell's internal resistance causes voltage to sag below the processor's minimum threshold while the fuel gauge still reads 20–30%. The phone interprets this as a hardware fault and shuts down to protect the SoC. One complete discharge to automatic shutoff, followed by a full uninterrupted charge, recalibrates the coulomb counter and resolves most cases.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB charging not recognised on first connection after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a cold cell install, the charge IC on the U9508 sometimes fails to negotiate the charging profile on the first connection, especially if the replacement cell came off the shelf at a low state of charge. Plug into a standard 5V USB source — not a fast charger — and leave it connected for at least 10 minutes without pressing the power button. Once the cell climbs above approximately 3.0V, the BMS exits lockout and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404344688730,"sku":"BWCS-HU9508SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404344721498,"sku":"BWCS-HU9508SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404344754266,"sku":"BWCS-HU9508SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HU9508SL-1.webp?v=1779369805","url":"https:\/\/batteryweb.com\/products\/huawei-honor-2-replacement-battery-37v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
