It replaces part numbers LIBR160 and 35H00082-00M directly. If your XDA Atoms no longer holds a charge or powers off unexpectedly, this cell is the correct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXDA Atoms fit:\u003c\/strong\u003e\n    The XDA Atoms uses a dedicated battery bay with a fixed connector pitch and BMS communication line. This cell matches that footprint at 54.03 × 39.60 × 11.37mm and communicates correctly with the device's charge controller — no hardware modification required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the cell through a full charge cycle and monitored BMS handshake and cutoff thresholds. The protection circuit triggered correctly at the low-voltage floor and the charge IC accepted the cell without error flags.\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 automatic shutdown, then charge uninterrupted to 100%. The XDA Atoms fuel gauge IC is calibrated to the old cell's discharge curve — skipping this step causes the percentage display to read inaccurately from the first charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the XDA Atoms reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe XDA Atoms uses a coulomb-counter fuel gauge IC that builds its capacity model from accumulated charge and discharge data on the original cell. When a new cell goes in, that stored model no longer matches the actual discharge curve of the replacement. The gauge will read confidently but incorrectly — typically showing full charge when the cell is at 80%, or jumping several percentage points without load change. One full uninterrupted discharge-to-shutdown followed by a complete charge cycle forces the IC to rewrite its reference curve against the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the XDA Atoms after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops sharply under the load of the radio modem or backlight — a voltage cliff the fuel gauge didn't anticipate. The BMS reads a voltage collapse below its cutoff floor and disconnects the cell to protect it, even though the reported percentage looks safe. It is not a faulty battery — it is an uncalibrated gauge misjudging remaining capacity. After one full recalibration cycle, the gauge learns where the actual voltage cliff sits and begins shutting down at 5–8% instead. If the problem persists after calibration, measure resting cell voltage with a multimeter — it should read above 3.6V at what the device reports as 30%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405184565338,"sku":"BWCS-DS710XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405184598106,"sku":"BWCS-DS710XL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405184630874,"sku":"BWCS-DS710XL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DS710XL-1.webp?v=1779370332","url":"https:\/\/batteryweb.com\/products\/o2-xda-atoms-replacement-battery-37v-2250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
