It uses OEM part number PA32 and matches the original cell format at 66.70 × 38.50 × 21.50mm. Fit this battery when the original pack no longer holds charge or the speaker shuts down unexpectedly during playback.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFlare 1 and Flare 2 compatibility:\u003c\/strong\u003e\n    Both A3161 and A3165 share the same 7.4V cell bay, connector pinout, and BMS handshake protocol — one battery fits both without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the PA32 cell through charge and discharge cycles on a Flare 1 unit. The BMS accepted the pack without fault codes, held the full 2600mAh rating, and the protection circuit tripped cleanly at the low-voltage cutoff during drain testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge calibration on first use:\u003c\/strong\u003e\n    After fitting this battery, run the speaker until it powers off from low voltage, then charge it uninterrupted to 100%. The Flare's fuel gauge recalibrates to the new cell this way — skipping this step causes the indicator to misread state-of-charge from day one.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCapacity fade from constant desk-top charging on the Flare 1\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Flare 1 is commonly left plugged in between uses — charged to 100%, then topped off again before it drops below 50%. Li-ion cells degrade faster when cycled only in the upper voltage band. This shallow-cycling pattern accelerates capacity loss because the cell spends most of its life near peak voltage stress. To slow this down, discharge to below 20% at least once a month before recharging to full.\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\"\u003eThis happens when the cell voltage sags under the combined current draw of the amplifier and Bluetooth radio at high volume. The amplifier clips before the low-voltage cutoff triggers because the cell can no longer hold voltage under load, even though the indicator still shows charge remaining. It is not a speaker fault — it is a sign the battery can no longer sustain its discharge curve under peak draw. Replace the battery and verify the cell holds above 7.0V under load during playback.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416203919450,"sku":"BWCS-AKS200SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416203952218,"sku":"BWCS-AKS200SL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416203984986,"sku":"BWCS-AKS200SL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AKS200SL-1.webp?v=1779760767","url":"https:\/\/batteryweb.com\/products\/anker-soundcore-flare-1-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
