It fits the WS10 Pro directly and restores wireless audio playback when the original cell no longer holds a usable charge. Capacity is rated at 19.24Wh, matching the original pack specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWS10 Pro platform fit:\u003c\/strong\u003e\n    The WS10 Pro uses a single-cell Li-ion configuration at 3.7V nominal. This pack shares the same voltage rail and connector pinout as the factory unit, so the speaker's charge controller and battery indicator read it correctly without recalibration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the WS10 Pro platform. The BMS engaged cutoff cleanly at low voltage and accepted charge input from the speaker's USB charging circuit without triggering a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle for WS10 Pro users:\u003c\/strong\u003e\n    The WS10 Pro is typically left on a desk and topped off constantly. Let the battery drop below 20% at least once a month before recharging — continuous shallow cycling without a full discharge causes fuel gauge drift and accelerates capacity fade on the 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 WS10 Pro\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt high volume, the amplifier and Bluetooth radio draw current simultaneously, causing a combined load spike the cell may not sustain if it's aged or partially discharged. This voltage sag triggers the BMS to reduce output, cutting the radio connection momentarily. It's not a pairing issue — it's a power delivery problem. A fresh cell at full charge handles the combined amp-plus-radio draw without the sag that drops the connection.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWS10 Pro won't wake from USB when battery is fully drained\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the cell sits discharged for an extended period, it can drop below the minimum acceptance voltage for the speaker's USB-C charging circuit. The charger sees the voltage as out of range and refuses to initiate a charge session, so the speaker appears completely dead. The fix is to apply a low-current pre-charge — some USB wall adapters will do this automatically; others won't. If the speaker shows no response after 30 minutes on charge, try a different adapter rated at 5V\/1A and leave it connected for at least an hour before checking again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416178196570,"sku":"BWCS-HSP100SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416178229338,"sku":"BWCS-HSP100SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416178262106,"sku":"BWCS-HSP100SL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HSP100SL-1.webp?v=1779760588","url":"https:\/\/batteryweb.com\/products\/hp-ws10-pro-speaker-replacement-battery-37v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
