JBL Battery 400 for PB STAGE320 & XTREME 4

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.

Durable 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.

Works with 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.

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.
