It fits the XP5, XP5700, XP5s, and XP5800. Capacity is 11.4Wh, matching the original cell footprint at 65.10 × 43.74 × 9.90mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXP5 family compatibility:\u003c\/strong\u003e\n    The XP5, XP5700, XP5s, and XP5800 all share the BAT-03180-01S form factor, connector pinout, and BMS handshake. Swapping between these models does not require any firmware or hardware change — the fuel gauge IC reads the same cell chemistry across all four variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on XP5-series hardware and confirmed the BMS accepted the cell without error flags. The protection circuit tripped correctly at the low-voltage cutoff and resumed charging without a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first installation, disable fast charging and run one full discharge-to-charge cycle before enabling it again. The fuel gauge IC on the XP5 calibrates its coulomb counter against the cell's actual discharge curve — skipping this step can cause the OS to misreport state of charge for weeks.\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 XP5 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity fault. When the XP5 is running the modem at full power — push-to-talk, cellular data, or GPS — the current draw spikes and the new cell's terminal voltage drops faster than the fuel gauge IC expects. The OS reads 25% state of charge, but the cell voltage under load has already fallen below the BMS cutoff threshold of around 3.0V. One full discharge-charge cycle lets the coulomb counter remap the actual voltage-to-capacity curve of the new cell and eliminates most cliff shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone does not power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf this cell was stored in a discharged state, the cell voltage may have dropped below 2.5V — the BMS enters lockout to prevent damage to the lithium cells. A standard USB cable will not wake the phone because the system bus has no power to negotiate the charge protocol. Connect the XP5 to a wall charger rated at 5V\/1A or higher and leave it for 20–30 minutes without pressing the power button — the charge IC will trickle current into the cell until voltage recovers above 3.0V, at which point the BMS exits lockout and the phone will boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391982075994,"sku":"BWCS-SXP570SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391982108762,"sku":"BWCS-SXP570SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391982141530,"sku":"BWCS-SXP570SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SXP570SL-1.webp?v=1779142738","url":"https:\/\/batteryweb.com\/products\/sonim-xp5-replacement-battery-38v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
