Introduction
Go to step 1 ↓Use this guide to replace the battery in your JBL Charge. Compare your speaker with the photos before you begin.
A worn battery may cause significantly reduced playback time. Failure to power on or poor sound quality can have other causes, so check the power supply and symptoms before replacing the battery.
Before starting, reduce the battery charge below 25% if the speaker still works and the battery shows no signs of damage. Turn off the speaker and disconnect all cables.
If the battery is swollen or damaged, do not proceed with this guide as written.
Do not puncture, bend, or crush the battery. Use a plastic spudger when working directly against the battery. The battery remains connected during the initial disassembly steps.

Your instructions state to replace the white cover, but do not say why it has to be replaced. Can you expound, please? Thank you,
Hi Delton, that is a good question. The entire cover has to be replaced if one is replacing the aux/USB ports.
You can ignore that note in this battery replacement guide. Good catch!
