All three share the same flat-pack cell format and connector pinout. Swap it when the original no longer holds a charge or the speaker shuts down mid-session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMicro, Micro Wireless 2013, and Clip+ fit:\u003c\/strong\u003e\n    These three models share a common 3.7V single-cell architecture and the same JST-style connector, so one cell covers all. The BMS on each device communicates over the same two-wire path — no firmware mismatch issues.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the Micro platform. The protection circuit tripped correctly at low-voltage cutoff, and charge acceptance from a 5V USB source tracked the expected CC\/CV curve through to termination.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle for the Micro:\u003c\/strong\u003e\n    If you keep the Micro plugged in at your desk and top it off constantly, let it run down below 20% at least once a month before recharging. Constant partial-charge cycles cause fuel gauge drift on this cell and accelerate capacity fade faster than occasional full discharges do.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the JBL Micro plays loud, then cuts to silence before the indicator hits empty\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAt high volume, the Micro's amplifier draws a sharp current spike that briefly collapses cell voltage below the BMS cutoff threshold — even when the state-of-charge gauge still reads mid-range. The original cell handles this because its internal resistance is low when new. An aged cell's higher internal resistance means the voltage drop under that spike is steeper, triggering a protective shutdown. A fresh cell with lower internal resistance keeps the voltage rail stable through those transient peaks.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eJBL Micro won't wake from USB after sitting unused for weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the Micro sat unused long enough, the cell voltage drops below 2.5V — the minimum most USB charging circuits will accept before they attempt a normal charge cycle. The device appears completely dead even when plugged in. Connect it to a 5V USB source and leave it undisturbed for 20–30 minutes; the protection circuit needs time to trickle-recover the cell to a voltage the charge IC will recognise, typically around 3.0V, before normal charging begins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416226791514,"sku":"BWCS-JMM100SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416226824282,"sku":"BWCS-JMM100SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416226857050,"sku":"BWCS-JMM100SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JMM100SL-1.webp?v=1779761043","url":"https:\/\/batteryweb.com\/products\/jbl-micro-replacement-battery-37v-700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
