It carries OEM part numbers B0P9O100, 35H00222-00M, 35H00222-01M, and BOP90100. Dimensions are 61.04 × 54.48 × 4.22mm — match these before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDesire 610 variant compatibility:\u003c\/strong\u003e\n    The D610t, D610n, and D610x share the same battery bay geometry, connector pinout, and 3.8V nominal rail as the base Desire 610. One cell fits all of them because HTC used a single battery specification across the regional lineup.\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 Desire 610 platform. The BMS communicated correctly with the device charge IC, and no false full-charge flags appeared during the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After swapping cells, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC build an accurate discharge curve against the new cell before high-current charging begins on an uncalibrated coulomb counter.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still using the discharge curve from the old, degraded cell. The new cell has a steeper voltage drop under modem and screen load than the old curve predicts. When actual cell voltage hits the hardware cutoff threshold, the phone shuts down even though the OS shows charge remaining. One full slow discharge-charge cycle forces the coulomb counter to remap against the new cell's actual voltage profile. After that cycle, shutdowns at false percentages typically stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after sitting in storage with a flat cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA lithium-polymer cell that drops below approximately 2.5V per cell triggers BMS lockout — the protection circuit opens and blocks current flow to prevent damage. Plugging straight into the phone may show nothing on screen. Connect the phone to a wall charger rated at least 5V\/1A and leave it for 20–30 minutes without pressing the power button — the charge IC will trickle current into the cell until voltage recovers above the BMS re-enable threshold, typically around 3.0V, at which point the phone will begin a normal boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404208635994,"sku":"BWCS-HTD610XL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404208668762,"sku":"BWCS-HTD610XL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404208701530,"sku":"BWCS-HTD610XL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTD610XL-1.webp?v=1779369391","url":"https:\/\/batteryweb.com\/products\/htc-desire-610-replacement-battery-38v-2040mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
