It fits the original battery slot and matches the OEM part numbers 35H00077-00M and TRIN160. If the original cell has degraded past the point of holding a usable charge, this replaces it directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSPV M700 fitment:\u003c\/strong\u003e\n    The M700 uses a slim Li-Polymer cell at 66.50 x 44.00 x 4.50mm — a form factor specific to this handset. The connector and BMS communication line match the original HTC-platform hardware that Orange branded for this device.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full discharge and charge sequences and confirmed the BMS held charge acceptance within spec. The protection circuit tripped correctly at low-voltage cutoff and recovered without issue on recharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On first use, run one complete discharge down to auto-shutoff, then charge uninterrupted to 100% before using the device normally. The M700's fuel gauge IC was calibrated to the original cell's discharge curve — a full cycle resets it against the new cell so percentage readings stabilise.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SPV M700 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe M700 uses a coulomb-counting fuel gauge IC that builds its capacity model from historical charge and discharge data. When the original cell is replaced, the IC is still referencing the old cell's degraded discharge curve. This causes the percentage display to read high early in discharge and then drop sharply. One full discharge-to-shutoff followed by an uninterrupted charge to 100% forces the IC to relearn the curve against the new cell. After that single cycle, percentage readings will track correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet recalibrated and the phone hits voltage cutoff earlier than the displayed percentage suggests. Under screen or radio load, the cell voltage sags — if the IC hasn't mapped the new cell's voltage-to-capacity relationship, it doesn't predict the cliff correctly. The result is an abrupt shutdown well above 0% shown on screen. Run one full discharge cycle to auto-shutoff first, then recharge to 100%. After recalibration, the gauge will catch the voltage drop early enough to give an accurate low-battery warning before cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405214449754,"sku":"BWCS-DD810SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405214482522,"sku":"BWCS-DD810SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405214515290,"sku":"BWCS-DD810SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DD810SL-1.webp?v=1779370349","url":"https:\/\/batteryweb.com\/products\/orange-spv-m700-replacement-battery-37v-1250mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
