It fits both models — same cell format, same voltage rail, same connector footprint. Swap it in when the original cell can no longer hold a usable charge across a full outdoor session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTerrain Mini and Terrain Mini XT compatibility:\u003c\/strong\u003e\n    Both models use the same 18650 cell format with a matching BMS handshake threshold. One replacement covers either unit 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 Terrain Mini platform. The onboard BMS accepted the cell without fault codes, and the fuel gauge tracked accurately across the full voltage window from 4.2V down to the 2.8V cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle for this speaker:\u003c\/strong\u003e\n    The Terrain Mini is often used at a desk or on a shelf and topped off before it drops below 50%. Run it down below 20% at least once a month before recharging — constant shallow cycling causes fuel gauge drift and accelerates capacity fade on this Li-ion cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBluetooth dropping at high volume on the Terrain Mini\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAt maximum or near-maximum volume, the amplifier and Bluetooth radio draw current simultaneously. On a degraded or deeply discharged cell, that combined load causes voltage sag past the BMS's low-voltage trip point. The BMS interrupts power briefly to protect the cell, and the radio loses sync. A fresh cell at full charge holds the voltage rail stable under that combined draw — Bluetooth stays connected.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSpeaker won't wake from USB-C charge after sitting unused for weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the Terrain Mini sits unused long enough, the cell voltage drops below the minimum USB-C PD acceptance threshold — typically around 2.5V — and the charger refuses to negotiate a charge session. The fix is to apply a low-current trickle using a compatible charger for 10–15 minutes to bring the cell above 3.0V, at which point normal USB-C charging resumes. If the cell doesn't recover above 3.0V within 20 minutes of trickle input, the original cell has failed and needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416195661914,"sku":"BWCS-SKM100SL-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416195694682,"sku":"BWCS-SKM100SL-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416195727450,"sku":"BWCS-SKM100SL-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SKM100SL-1.webp?v=1779760792","url":"https:\/\/batteryweb.com\/products\/skullcandy-terrain-mini-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
