JBL Pulse 2 Troubleshooting

Battery weakening over time, hampering the ability to charge.

The JBL Pulse features a LED display next to the auxiliary port which shows the current battery charge. It has 5 bars that light up, each representing a 20% charge. However, a faulty USB cord may also affect the connection.

First, make sure the device isn’t fully charged or completely dead. If the problem persists even after the battery is recharged, you may want to consult the device's warranty or any accompanying manuals for more options. Finally, although the JBL Pulse 2 is splash-proof, you should not confuse this with being waterproof. Too much water can wreak havoc with the JBL's system, and if the splash-proofing has been taken to the max, the risk of water damage can increase exponentially. If water damage is the problem, your options are fairly limited, but you should consult the warranty to see what's covered and explore options for resolution from there.

If the battery isn’t charging at all, it may become necessary to replace the battery. For instructions on how to replace the battery, please follow the link here.
