It replaces OEM part GSP-2S10-CH6A and restores the speaker's wireless audio and USB charging output when the original cell has degraded or failed. Capacity figure is 33.3Wh at the rated 7.4V nominal.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCharge 6 fit and connector:\u003c\/strong\u003e\n    The Charge 6 uses a two-cell series Li-ion pack with a multi-pin connector that carries both cell balance data and temperature sensing. The BMS inside the speaker reads both signals on power-up — a pack missing either line will not initialise, so this replacement includes the matching harness and pin layout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a Charge 6 unit through charge, full audio playback load, and USB passthrough output. The BMS accepted the cell chemistry handshake on first power-up, and the protection circuit tripped correctly at the low-cell-voltage cutoff threshold without nuisance shutdowns during normal draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle for Charge 6 users:\u003c\/strong\u003e\n    If the speaker sits on a desk and gets topped off before dropping below 50%, the fuel gauge drifts over weeks and the battery indicator becomes inaccurate. Run the speaker down below 20% at least once a month before recharging to recalibrate the gauge and slow 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 shows full charge but audio cuts out after extended play\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Charge 6 amplifier draws a spike of current each time bass transients hit at high volume. If the Li-ion cells have degraded, internal resistance rises and voltage sags sharply under that spike — even when the fuel gauge still reads high. The speaker's protection circuit sees the sag as a low-voltage condition and shuts audio output before the indicator reaches empty. Replacing the pack with fresh cells lowers internal resistance and eliminates the sag that triggers the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-C won't wake the Charge 6 when the battery is deeply discharged\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUSB-C Power Delivery negotiation requires the device to pull a minimum voltage on the CC pins before the charger steps up to full charging voltage. If the Charge 6 battery has dropped below roughly 2.5V per cell, the BMS locks out output and the speaker cannot pull enough current to begin that handshake. The fix is to use a standard 5V USB-A cable first — this bypasses PD negotiation and trickle-charges the pack until cells recover above 3.0V per cell. Once the indicator LED blinks, switch back to the USB-C cable for normal charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416179179610,"sku":"BWCS-JML600SL-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416179212378,"sku":"BWCS-JML600SL-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416179245146,"sku":"BWCS-JML600SL-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JML600SL-1.webp?v=1779760588","url":"https:\/\/batteryweb.com\/products\/jbl-charge-6-replacement-battery-74v-4500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
