Battery 400 - 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 that's guaranteed to work with your speaker.

Monitor playtime in the JBL PartyBox App

Just use your JBL PartyBox app to check the health of your JBL PartyBox Club current battery. When the Battery State of Health (SOH) reading lets you know it's time, replacing the battery takes just seconds.

Battery 400 - Fast Charge

10 minutes fast charge will give your JBL PartyBox Stage 320 and Xtreme 4 an extra 2 hours of playtime.
