It replaces OEM part numbers PH26B and AHTXDSSN. If the original cell has degraded and the phone no longer holds a charge, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSPV M2000 and M2500 compatibility:\u003c\/strong\u003e\n    Both devices share the same battery bay dimensions and voltage rail. The connector pinout and BMS handshake are identical across both models, so one cell covers either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on the SPV platform and confirmed the BMS communicates charge state correctly to the OS. The protection circuit responded at both the high-voltage cutoff and the low-voltage floor without tripping the device into a false shutdown loop.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, run one complete discharge to auto-off and then a full uninterrupted charge before normal use. The SPV's fuel gauge IC was calibrated to the original cell's discharge curve — one full cycle resets its reference point against the new 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 SPV M2000 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still holds the old cell's discharge curve in memory. The new cell has a steeper voltage cliff under modem or screen load than the aged original, so the phone cuts power before the gauge registers critical. The BMS on the replacement cell is not at fault — the problem is the mismatch between the stored discharge model and the actual cell behaviour. One full discharge-to-shutdown followed by a complete charge retrains the coulomb counter and eliminates the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells in long-term storage self-discharge slowly. If the cell drops below approximately 2.5V per cell, the BMS enters lockout to prevent damage and the phone will show no response to the power button. Connect the phone to a wall charger — not a USB port — and leave it for 20–30 minutes before attempting to power on. A wall charger delivers enough current to push the BMS out of lockout, where a low-output USB port may not. If the screen still shows nothing after that period, hold the charge for a further hour before the first boot attempt.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409438638170,"sku":"BWCS-PH26BDL-1","price":40.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409438670938,"sku":"BWCS-PH26BDL-2","price":46.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409438703706,"sku":"BWCS-PH26BDL-3","price":51.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PH26BDL-big.webp?v=1779579689","url":"https:\/\/batteryweb.com\/products\/orange-spv-m2000-replacement-battery-37v-4200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
