It matches OEM part numbers XP3.20-0001100, XP-0001100, BAT-01750-01 S, and VR-01. It slots directly into the same battery bay with no modification to the device.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXP1300 and XP3300 series compatibility:\u003c\/strong\u003e\n    Both the XP1300 and XP3300 lines share the same 3.7V battery rail and physical connector footprint. The BMS handshake protocol is consistent across these models, so one cell covers the full platform without any firmware or connector workaround.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full discharge-charge sequence on the XP1300. The BMS accepted the cell without error flags, held voltage above 3.5V through mid-discharge, and cut off cleanly at the low-voltage threshold — no spurious fault codes triggered during the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On the first use after installation, disable fast charging and run one complete discharge down to automatic shutdown, then charge to 100% uninterrupted. This gives the fuel gauge IC one clean pass to map the new cell's discharge curve before it starts reporting percentages to the OS.\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 Sonim XP1300 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe XP1300's fuel gauge IC retains the discharge curve of the old cell in its coulomb counter after a swap. When the OS reports 25%, the new cell's actual resting voltage may already be near the modem's minimum operating threshold — around 3.5V under load. A high-draw event like an active LTE call or GPS lock pulls current the gauge didn't anticipate, and the protection circuit trips before the displayed percentage reaches zero. One full unassisted discharge-charge cycle forces the coulomb counter to relearn the new cell's curve and eliminates most premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery compartment during first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell arrives with a slightly higher internal impedance than a broken-in cell. During the first charge cycle, the charge IC pushes current into that higher-impedance cell, and the resistance difference converts to heat. This is normal on cycle one and typically resolves by cycle three as the cell's impedance drops. If the housing stays warm past the third full charge, check that the charge IC hasn't locked into a fast-charge profile — drop to standard charge mode and monitor temperature at the 3.9V stage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405043073114,"sku":"BWCS-SXP130SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405043105882,"sku":"BWCS-SXP130SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405043138650,"sku":"BWCS-SXP130SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SXP130SL_1.webp?v=1779369859","url":"https:\/\/batteryweb.com\/products\/socketmobile-sonim-xp1300-replacement-battery-37v-1750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
