Introduction

Go to step 1 ↓

In this Replacement Guide, you will find the steps and process to replace the battery in the JBL Go 4.

The Battery provides power to the entire device. A failing battery can have reduced battery life or none at all, it can also begin to overheat or shut down at random times.

Before using this guide, make sure to review the troubleshooting page—oftentimes, there can be other reasons for shortened battery life.

Note: The device used in this guide is a non-genuine model, so the internal components may look different from those in your authentic device. However, the replacement procedure remains roughly the same and should still apply to your device.

  Remove the grille.

2. Step 2
  Insert an opening tool in the opposite corner, lifting carefully.
  
  Slide the tool along the edge until the cover pops off.
  
  Gently pull the housing up and to the side.
  
  When the plate becomes loose, be incredibly gentle to avoid damaging the cable that connects the battery to the housing.

4. Step 3
  Find the connection between the motherboard and the battery cable as labeled.
  
  Gently depress the plastic tabs and slowly wiggle the connector until it comes free.
  
  Be incredibly gentle with this connector as any excessive force can damage the motherboard.

6. Step 4
  Insert an opening tool beneath the battery, on the side opposite to the battery cable.
  
  Using a lever motion, pry the battery out slowly, sliding it further under to break the adhesive up.
  
  It's important to note that the battery is held on with a small adhesive pad, so more force than should feel necessary will be needed.
