Features and Benefits

 A great host always has a spare battery

 Keep the party going twice as long by having a spare JBL Battery 400 on

hand. Just insert it into the battery slot in the back of your JBL PartyBox

Stage 320 when the first one loses its charge. Each battery has enough

power for up to 18 hours of playtime, which means you could keep the party

going for up to 36 hours.

 Guaranteed JBL Quality

 Give yourself the peace of mind that comes from a trustworthy, reliable JBL

Battery 400 that’s guaranteed to work with your speaker.

 Fast charge

 10 minutes fast charge will give your JBL PartyBox Stage 320 and Xtreme 4

an extra 2 hours of playtime.

Monitor playtime in the JBL PartyBox App

 Just use your JBL PartyBox app to check the health of your JBL PartyBox

Stage 320’s current battery. When the Battery State of Health (SOH) reading

lets you know it’s time, replacing the battery takes just seconds.

 Compatible with JBL PartyBox Stage 320 and Xtreme 4

 JBL Battery 400 is only compatible with the JBL PartyBox Stage 320 and JBL

Xtreme 4 wireless Bluetooth™speaker. Other speakers in the JBL PartyBox

series and JBL portable series have different battery requirements.
