The SA10120 is a portable satellite radio receiver used in vehicles and for on-the-go listening away from a fixed power source. Capacity figure is taken directly from product data — 13.32Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSA10120 Roady fit:\u003c\/strong\u003e\n    The SA10120 Roady runs a single-cell 3.7V architecture with a compact LP103450 form factor. The connector pinout and BMS handshake match the original cell, so the protection circuit communicates correctly with the device's charge management IC.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the SA10120 platform. The BMS registered no fault codes, the charge IC accepted current normally, and the protection circuit tripped correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-storage activation tip:\u003c\/strong\u003e\n    If the Roady has been sitting unused for months, connect it to its car adapter or home dock before attempting to power on. Cells stored at low state-of-charge can drop below 3.0V, triggering deep-discharge protection that blocks normal startup until a slow trickle charge restores the cell above the recovery threshold.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping after replacing the SA10120 cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SA10120 Roady uses a voltage-threshold method to estimate remaining charge rather than a fuel gauge IC with coulomb counting. After a cell swap, the device has no baseline for the new cell's voltage curve, so the indicator reads erratically until it recalibrates. Run the battery down to near-empty, then charge it to full in one uninterrupted session. After one or two complete cycles the percentage reading stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSatellite radio playback cutting out before the battery indicator shows empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SA10120's audio output stage and RF tuner draw higher current than the idle display alone. Near the end of discharge, cell voltage sags under that combined load even though the resting voltage still reads above the empty threshold. The device shuts off to protect the cell before the indicator reaches zero. If this happens consistently, the cell voltage under load is dropping below 3.2V — a full recharge cycle should push the cutout point back toward the end of the charge curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381336539226,"sku":"BWCS-DXM120SL-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381336571994,"sku":"BWCS-DXM120SL-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381336604762,"sku":"BWCS-DXM120SL-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DXM120SL_1.webp?v=1778899987","url":"https:\/\/batteryweb.com\/products\/delphi-xm-satellite-radio-sa10120-roady-replacement-battery-37v-3600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
