It matches the OEM part number 077171 and fits the compact waterproof housing directly. Voltage, capacity at 9.62Wh, and connector orientation all match factory spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSoundLink Micro and 423816 compatibility:\u003c\/strong\u003e\n    Both model references share the same compact enclosure, the same 3.7V single-cell architecture, and the same BMS handshake protocol — one battery covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the SoundLink Micro's charge circuit and confirmed the BMS accepted the pack without fault codes, balanced cells correctly at top-of-charge, and held voltage through sustained audio playback at high output.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eShallow-cycle care for daily desk use:\u003c\/strong\u003e\n    The SoundLink Micro is often charged on a desk between short sessions, which means the cell rarely drops below 50% before recharging. Let the speaker run below 20% at least once a month before plugging in — this prevents fuel gauge drift and slows 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\"\u003eAudio distorting before the battery indicator reaches empty\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAs a Li-ion cell ages, its internal resistance rises. Under the combined current draw of the amplifier and the Bluetooth radio at high volume, terminal voltage sags below the threshold the amplifier needs to deliver clean output — even when the indicator still shows charge remaining. The result is audible clipping and distortion before the speaker shuts down. A fresh cell with lower internal resistance holds voltage through those current spikes, clearing the distortion. If distortion starts at moderate volume on a new pack, check that the USB-C port is clean and the charge cycle completed fully — cell voltage should reach 4.2V at end of charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSpeaker not waking from USB-C after sitting unused for weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA deeply discharged Li-ion cell can drop below the USB-C Power Delivery minimum acceptance voltage, so the speaker draws no current and appears completely dead when plugged in. The BMS blocks charging to protect the cell until a trickle pre-charge brings voltage back above roughly 2.5V. Use a USB-A to USB-C cable with a standard 5V charger rather than a PD negotiating charger — lower-voltage trickle entry is more likely to wake the pack. Leave it connected for at least 30 minutes before pressing the power button.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416219123802,"sku":"BWCS-BSE171SL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416219156570,"sku":"BWCS-BSE171SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416219189338,"sku":"BWCS-BSE171SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSE171SL-1.webp?v=1779760990","url":"https:\/\/batteryweb.com\/products\/bose-soundlink-micro-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
