It matches the OEM voltage rail and connector spec for that handset. Capacity is 8.88Wh, sourced against part numbers 35H00077-00M, 35H00077-02M, and TRIN160.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXPA v1510 fit:\u003c\/strong\u003e\n    The v1510 uses a fixed connector pinout tied to its charge IC and fuel gauge IC. This cell matches that pinout, so the BMS handshake completes on first boot without triggering a hardware fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran a full discharge-charge cycle on the v1510 platform. The BMS accepted the cell, charge current ramped correctly through CC-CV stages, and no thermal flags tripped at the charge IC.\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-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated state.\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 XPA v1510 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell has a slightly different internal impedance profile than the cell it replaces. Under peak modem or screen load, voltage can sag below the BMS cutoff threshold even when the fuel gauge still reads 20–30%. The fuel gauge IC was calibrated to the old cell's discharge curve, so it misreads available capacity on the new cell. One complete slow discharge down to auto-off, followed by a full charge, resets the coulomb counter and eliminates most unexpected shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eXPA v1510 reporting wrong battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC stores a learned discharge curve from the previous cell. When you install a new cell, that stored curve no longer matches the actual chemistry, so the percentage readout drifts — often jumping several points or freezing briefly. The fix is one full cycle: charge to 100%, let the phone discharge to auto-off under normal use, then charge back to 100% without interruption. After that cycle, the coulomb counter locks onto the new cell's curve and percentage accuracy stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405150027866,"sku":"BWCS-DD810XL-1","price":27.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405150060634,"sku":"BWCS-DD810XL-2","price":31.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405150093402,"sku":"BWCS-DD810XL-3","price":34.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DD810XL-big.webp?v=1779370298","url":"https:\/\/batteryweb.com\/products\/swisscom-xpa-v1510-replacement-battery-37v-2400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
