It slots into the Charge 6 chassis and restores wireless audio playback and the speaker's built-in USB charging output. Use it when the original cell no longer holds a charge or fails to reach a full state of charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCharge 6 fit:\u003c\/strong\u003e\n    The Charge 6 uses a two-cell 7.4V pack with a proprietary BMS handshake tied to part number GSP-2S10-CH6A. This replacement matches that cell configuration and connector pinout so the speaker's charge indicator and protection circuits communicate correctly with the pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on a Charge 6 unit. The BMS accepted the pack without fault codes, the fuel gauge tracked state of charge accurately across the full range, and the USB-C PD input negotiated correctly at each charge stage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCharge cycle care for desk-top use:\u003c\/strong\u003e\n    For speakers used daily on a desk and topped off constantly, run a full discharge 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 cells.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Charge 6 runs warm in its fabric housing during extended play\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Charge 6 amplifier generates heat under sustained loud output, and the Li-ion cells add their own discharge heat on top of that. The fabric housing traps both heat sources together rather than venting them the way a vented enclosure would. Sustained temperatures above 40°C accelerate cell degradation over time. If the speaker feels hot to the touch during long sessions, drop the volume to reduce amplifier draw and give the housing a break from direct sunlight or enclosed surfaces.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSpeaker won't wake from USB-C after sitting unused for weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA deeply discharged Li-ion pack can fall below the minimum acceptance voltage for USB-C PD negotiation — typically under 2.5V per cell. When the Charge 6 controller can't confirm a valid cell voltage, it won't initiate the charge handshake and the speaker appears completely dead. Plug into a USB-C source that supports 5V\/0.5A slow trickle — some chargers drop out because the speaker isn't responding with PD acknowledgement. Hold the connection for 15–20 minutes to allow trickle current to bring the cells back above 2.8V per cell before attempting a normal charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416179081306,"sku":"BWCS-JML600XL-1","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416179114074,"sku":"BWCS-JML600XL-2","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416179146842,"sku":"BWCS-JML600XL-3","price":74.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JML600XL-1.webp?v=1779760588","url":"https:\/\/batteryweb.com\/products\/jbl-charge-6-replacement-battery-74v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
