It fits the Wireless 360 Speaker directly, restoring wireless audio playback without replacing the unit. Capacity is sourced from the product specification — 18.2Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDell Wireless 360 Speaker fit:\u003c\/strong\u003e\n    The AE715 and AE715B share the same 7.4V two-cell Li-ion configuration, connector pinout, and BMS handshake protocol. Both part numbers are accepted by the speaker's charge controller without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and discharge on the Wireless 360 Speaker platform. The BMS engaged cleanly at both the high-voltage cutoff and low-voltage protection threshold, with no false shutdowns under combined amplifier and Bluetooth radio draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle for the Wireless 360:\u003c\/strong\u003e\n    This speaker is often left on a desk and topped off constantly. Let the battery drop below 20% at least once a month before recharging — skipping this causes fuel gauge drift and accelerates capacity fade on the Li-ion cells faster than intermittent full discharge would.\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\"\u003eThe Wireless 360 amplifier draws a short current spike at higher volume levels. When the Li-ion cells age or are partially degraded, internal resistance rises and voltage sags under that spike — even if the indicator still shows charge remaining. The audio clips because the amplifier rail drops below its minimum operating voltage before the BMS registers a low-battery event. A fresh cell at full 7.4V nominal restores the headroom the amplifier needs to operate cleanly through the volume range.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSpeaker fails to wake from USB charge after sitting unused for weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the Wireless 360 sits unused long enough, the pack can fall below the USB-C PD minimum acceptance voltage — typically around 2.5V per cell — and the charge controller will not initiate a charge cycle. The BMS interprets the pack as potentially unsafe and blocks input. To recover a deeply discharged pack, hold the power button while connecting USB, which forces a trickle pre-charge on some firmware versions; if that fails, the cells are below recovery threshold and replacement is the correct next step.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416206114906,"sku":"BWCS-DEL360SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416206147674,"sku":"BWCS-DEL360SL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416206180442,"sku":"BWCS-DEL360SL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEL360SL-1.webp?v=1779760823","url":"https:\/\/batteryweb.com\/products\/dell-wireless-360-speaker-replacement-battery-74v-2460mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
