The JBL Battery 400 is the ideal solution for users who want to get the most out of their speaker without being limited by its battery life. Designed specifically for the JBL PartyBox Stage 320 and the JBL Xtreme 4, this official replacement battery significantly extends listening sessions, outdoor events and late-night parties.

With a capacity of 68 Wh and modern lithium-ion technology, the Battery 400 offers up to 18 hours of additional battery life when used with a JBL PartyBox Stage 320. By having a second, fully charged battery to hand, you can double the usage time and achieve up to 36 hours of uninterrupted operation. Replacing the battery is quick and easy thanks to the accessible compartment at the rear of the speaker.

The battery also serves as an official replacement for the JBL Xtreme 4 when the original battery begins to lose capacity after several years of use. This compatibility helps extend the speaker’s lifespan whilst maintaining the performance levels specified by the manufacturer.

JBL has designed this battery to offer the same level of reliability as the products for which it is intended. The selected lithium-ion cells guarantee a stable power supply, excellent endurance and a long service life. Integration with the JBL PartyBox app also makes it easy to monitor the charge status and know when to replace the battery.

The Battery 400 also features a fast-charging function compatible with supported devices. A quick ten-minute charge provides up to two extra hours of battery life on a PartyBox Stage 320 or an Xtreme 4 – a real bonus when time is tight before an event or when using the device on the go.
