It matches the original cell dimensions at 63.54 × 50.55 × 5.15mm and slots into the same battery bay without modification. OEM part numbers 35H00211-00M-V, 35H00211-01M, 35H00221-01M, and B0PA2100 all cross-reference to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD310 and D310w Dual SIM fit:\u003c\/strong\u003e\n    Both variants run the same 3.8V battery rail with an identical connector pinout and BMS handshake. The Dual SIM model draws slightly more standby current from two active radios, but the battery hardware is interchangeable across the range.\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 D310 platform. The BMS accepted the charge IC handshake on the first cycle, reached full cutoff voltage without tripping protection, and held stable open-circuit voltage after rest.\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 for one complete discharge-to-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging begins on an uncalibrated register — preventing erratic percentage readings in the first week.\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 Desire 310 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Desire 310's fuel gauge IC retains the discharge curve from the old cell in its coulomb counter registers. When a new cell is installed, the reported percentage no longer maps accurately to actual cell voltage. Under modem or display load, the real cell voltage can drop below the 3.4V hardware cutoff while the OS still shows 25% remaining — triggering an abrupt shutdown. One full uninterrupted discharge-to-charge cycle resets the coulomb counter against the new cell's actual curve and eliminates this behaviour.\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 in storage self-discharge slowly, and if the cell voltage drops below approximately 2.5V, the BMS trips its deep-discharge lockout to protect the cell from damage. The phone will show no response at all — no charge animation, no boot. Connect the phone to a wall charger rated at least 1A and leave it for 20–30 minutes without interruption; the charge IC on the D310 applies a low trickle current to bring the cell back above the BMS re-enable threshold of around 2.9V. Once that threshold is crossed, normal charging resumes and the phone will power on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404246941786,"sku":"BWCS-HTD310XL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404246974554,"sku":"BWCS-HTD310XL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404247007322,"sku":"BWCS-HTD310XL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTD310XL-1.webp?v=1779369447","url":"https:\/\/batteryweb.com\/products\/htc-d310-replacement-battery-38v-2100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
