Avoid extreme temperatures: Do not leave the speaker in direct sunlight inside a car or near heating devices for extended periods. The maximum operating temperature should not exceed 45°C. Keep the charging port dry and clean: The speaker will issue a warning if the charging port is dirty or damp. Clean it thoroughly with a dry cloth or cotton swab and dry it completely before charging. Avoid overcharging and over-discharging: Do not frequently drain the JBL Xtreme4 PartyBox Club 320 Bluetooth speaker battery completely (until it automatically shuts down) before recharging. Maintaining the battery level between 20% and 80% is a recognized secret to extending the lithium battery’s cycle life.
Also, try to avoid leaving the JBL Xtreme4 PartyBox Club 320 Bluetooth speaker battery fully charged for extended periods. Use a charger with appropriate wattage: Although the speaker supports PD fast charging up to 20V/3A, prolonged use of excessively high-wattage chargers may exacerbate battery overheating. Make good use of the fast charging function: Both speakers support 2 hours of playback time with just 10 minutes of charging. Store at 40%-60% charge: If you plan not to use the speaker for several weeks or months, charge/discharge the battery to approximately 40%-60% and remove the spare battery (JBL Battery 400) from the speaker for separate storage. Choose a cool, dry environment: Store the JBL Xtreme4 PartyBox Club 320 Bluetooth speaker battery in a cool, dry, and dark place. If stored for more than 3 months, it is recommended to remove it and recharge/discharge it once to maintain its activity. Beware of battery bulging: If you find that the speaker casing is pushed up, or that the battery is bulging after removal, lithium-ion batteries may bulge due to damage, posing a safety hazard. Do not continue to use the speaker or attempt to disassemble it yourself.
Immediately stop using the JBL Xtreme 4 and dispose of it properly. Replacing the battery is simple: Replacing the built-in battery in the JBL Xtreme 4 is very convenient. Simply use a T20 Torx screwdriver to remove the two screws on the battery cover, open the cover, and pull the old battery upwards by pinching the orange pull strap. Software is also a good battery manager: Be sure to regularly update the firmware via the JBL Portable App or JBL PartyBox App to keep the speaker’s battery management system in optimal condition. If you find that the JBL Xtreme4 PartyBox Club 320 Bluetooth speaker battery is bulging, leaking, or overheating, stop using it immediately and recycle it according to environmental guidelines.
