Overview
The JBL Battery 400 (JBLBATTERY400) is an official spare battery accessory designed to extend playtime and keep your JBL PartyBox and Xtreme 4 speakers rocking for longer. When your speaker’s internal rechargeable battery starts to run low or degrade, simply swap in the Battery 400 to continue enjoying music without interruption — ideal for outdoor events, long parties, or extended travel.
Each JBL Battery 400 features a high‑capacity lithium‑ion cell with 7.2 V / 9444 mAh (68 Wh) capacity, giving up to about 18 hours of playtime on its own. When paired with your speaker’s installed battery, this effectively doubles total playtime to around 36 hours.
Thanks to fast‑charge capability, a quick 10‑minute charge can provide around 2 extra hours of listening — perfect if you need a quick boost while on the go. Battery health and usage can be tracked via the JBL PartyBox App, helping you know exactly when it’s time to swap or recharge.
The Battery 400 is officially compatible with the JBL PartyBox Stage 320 and JBL Xtreme 4 speakers. It’s designed to slide into the rear battery slot easily, making installation and replacement simple and tool‑free.
Compact and lightweight, this spare battery is a must‑have accessory for DJs, mobile entertainers, outdoor enthusiasts, and anyone who wants longer, uninterrupted sound from their compatible JBL speakers.
