It fits the Ambush (Y22-SK2013008) and uses OEM part number AEC633448. Dimensions are 48.75 × 33.32 × 8.66mm — measure your existing cell before fitting if unsure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAmbush platform fit:\u003c\/strong\u003e\n    The Ambush uses a single flat Li-Polymer pouch cell at 3.7V nominal to power both the amplifier board and the Bluetooth radio. This cell matches that voltage rail, connector footprint, and physical envelope so it slots into the existing battery bay.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Ambush charge controller and confirmed the BMS accepted the pack without fault flags. Charge current ramped normally through CC\/CV phases and the fuel gauge reported capacity correctly after two full cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly full-discharge tip for the Ambush:\u003c\/strong\u003e\n    The Ambush is commonly left on a desk and topped off before it drops below 50%. Do this consistently and the fuel gauge drifts — the speaker reads full but cuts earlier than expected. Let the cell discharge below 20% at least once a month before recharging to keep the gauge calibrated.\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 on the Ambush\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAt high volume the Ambush amplifier draws a short burst of current that the battery cannot sustain cleanly as the cell ages. Voltage sags under that peak draw and the amplifier clips — you hear distortion before the LED ever signals low battery. This is a cell-level problem, not a speaker fault. Replacing the cell restores the voltage headroom the amp needs; a healthy cell holds above 3.5V under load where distortion stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAmbush not waking from USB-C when the battery has fully drained\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Ambush sits discharged for several weeks the cell voltage can drop below 2.5V — the threshold where the charge controller refuses to begin a charge cycle as a safety measure. The speaker appears completely dead on USB-C. To recover, connect the cable and leave it for 15–20 minutes without pressing any button; some charge controllers run a trickle pre-charge at low current to bring the cell back above the acceptance threshold before switching to normal CC charge. If the indicator still does not light after 30 minutes, the cell has self-discharged past recovery and replacement is the only fix.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416207589466,"sku":"BWCS-SKY220SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416207622234,"sku":"BWCS-SKY220SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416207655002,"sku":"BWCS-SKY220SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/skullcandy-ambush-replacement-battery-37v-1300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
