It replaces the original cell when the pack no longer holds a full charge or fails to power on. Fits models Ounce XT, SKDY Ounce, and 2SKSK1844.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOunce XT \/ SKDY Ounce platform:\u003c\/strong\u003e\n    These models share the same 18650 cell bay, 3.7V nominal rail, and charge management circuit. One cell fits all three listed model numbers without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the Ounce XT board. The BMS accepted the cell cleanly, balanced charge terminated at 4.2V, and protection cutoff triggered correctly at the low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle for Ounce XT users:\u003c\/strong\u003e\n    Let the speaker run down below 20% at least once a month before recharging. Constant top-off charging without a full discharge causes fuel gauge drift — the speaker reports full charge while actual cell capacity quietly shrinks over weeks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAudio distorting before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAs the 18650 cell ages, internal resistance rises. Under the combined current draw of the amplifier and Bluetooth radio at high volume, terminal voltage sags below what the amp needs — even if the fuel gauge still shows charge remaining. The amplifier clips before the BMS low-voltage cutoff fires. On a fresh 2600mAh cell with low internal resistance, voltage sag under full load stays within the amplifier's operating window and clipping stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSpeaker won't wake from USB-C after sitting unused for weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA deeply discharged 18650 cell can drop below the minimum acceptance voltage for the Ounce XT's USB-C charge circuit — typically around 2.5V. The charge controller sees the cell as a fault condition and refuses to start. Plug into a USB-A charger with a lower minimum acceptance threshold first; this can trickle enough current in to bring the cell back above 3.0V. Once the cell recovers past 3.0V, a standard USB-C connection will resume normal charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416193761370,"sku":"BWCS-SKO100SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416193794138,"sku":"BWCS-SKO100SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416193826906,"sku":"BWCS-SKO100SL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SKO100SL-1.webp?v=1779760742","url":"https:\/\/batteryweb.com\/products\/skullcandy-ounce-xt-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
