It fits devices running OEM part numbers DIAM100, DIAM160, 35H00113-003, and 35H00113-03M. Physical dimensions are 41.72 × 40.60 × 15.95mm — confirm your original cell matches before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDiamond \/ Touch Diamond platform fit:\u003c\/strong\u003e\n    The Diamond 100 and P3700 share the same battery bay dimensions and voltage rail, so one cell covers the full lineup. The connector orientation and BMS contact pad layout are identical across these variants.\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 Diamond 100 unit. The BMS held steady through full charge termination, and the protection circuit tripped correctly at the low-voltage cutoff threshold without latching.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable any fast-charge accessory and run one complete discharge-to-charge cycle at standard current. This lets the fuel gauge IC map the new cell's discharge curve before it locks in percentage readings.\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 HTC Diamond after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HTC Diamond's fuel gauge IC was calibrated to the original cell's internal resistance profile. A new cell with different impedance causes the IC to misread remaining capacity. When the modem transmits or the screen peaks in brightness, current draw spikes and voltage briefly sags below the shutdown threshold — even if the gauge still shows 25%. One full discharge-charge cycle at standard current lets the IC re-anchor its curve to the new cell and eliminates most premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells stored uncharged self-discharge over weeks and can drop below 2.5V per cell — the point where the BMS locks out to prevent damage. The Diamond won't respond to the power button in this state. Connect the original HTC charger and leave it for 15–20 minutes without attempting to power on; the charge IC trickle-charges the cell back above the BMS re-enable threshold, typically around 2.9V, before switching to normal charge current.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405161660506,"sku":"BWCS-HDM100HL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405161693274,"sku":"BWCS-HDM100HL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405161726042,"sku":"BWCS-HDM100HL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDM100HL-1.webp?v=1779370333","url":"https:\/\/batteryweb.com\/products\/htc-diamond-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
