It fits the Pill XL and J273 variants. Swap it in when the speaker no longer holds a charge or shuts off unexpectedly during playback.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePill XL and J273 compatibility:\u003c\/strong\u003e\n    Both variants run the same 7.4V cell configuration with the same connector and BMS handshake protocol. This replacement matches that spec exactly — the speaker's charge controller will recognise the pack without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on the Pill XL platform. The BMS communicated correctly with the speaker's fuel gauge, and the protection circuit tripped as expected at low-voltage threshold — no false cutoffs during normal audio playback.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle on daily-use speakers:\u003c\/strong\u003e\n    If the Pill XL stays plugged in or gets topped off constantly, discharge it below 20% at least once a month before recharging. Shallow cycling without a full discharge causes fuel gauge drift, and the speaker will start reporting inaccurate charge levels long before the cell actually degrades.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Pill XL shows full charge but audio cuts out after extended play\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pill XL's fuel gauge relies on a calibrated charge curve. When the battery has been repeatedly topped off without full discharge cycles, the gauge drifts — it reads higher than the actual cell state. The speaker's protection circuit then sees a sudden voltage drop at what it thinks is mid-charge and triggers a cutoff. Replacing the battery and running two full discharge-to-recharge cycles re-calibrates the gauge to the new cell's curve.\u003c\/p\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\"\u003eAt high volume, the Pill XL's amplifier pulls a spike of current that briefly sags the cell voltage below the clean-audio threshold. An aged or partially degraded cell has higher internal resistance, which makes that sag sharper and longer. The amplifier clips under that sag, producing distortion even though the indicator still shows charge remaining. A fresh 6800mAh cell at full charge holds the voltage rail steady enough to suppress that clipping — check that the replacement is charged to at least 8.2V before first use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416231968858,"sku":"BWCS-BTP273XL-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416232001626,"sku":"BWCS-BTP273XL-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416232034394,"sku":"BWCS-BTP273XL-3","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTP273XL-1.webp?v=1779761042","url":"https:\/\/batteryweb.com\/products\/beats-pill-xl-replacement-battery-74v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
