How To

Many Harman Kardon, JBL and AKG products run on rechargeable batteries. In most cases, these batteries will provide years of excellent service and keep the music playing for many hours.

WARNING – the rechargeable batteries inside our products are not user-serviceable. Please do not attempt to open the product or replace the battery. Doing so will void your warranty.

Battery issues fall into three categories:

• Your speaker or headphones run out of power after only a short time.

• The speaker will not play at all because the battery will not hold a charge.

• When you plug in the cable to charge your speaker, sometimes it charges and sometimes it does not- the red charging LED or other indicator might not come on.

  Here are some things to try that often fix these issues.

1. It could be as simple as a bad USB charging cable. If you have other charging cables, give them a try. (Be sure that the cable has the same type of connector as the original one that came with your product.)

2. Same for the charger- if your product charges by USB, try a different USB charger. Be sure that it is rated at least 2.0a (2 amps) output.

3. Try other electrical outlets at your location to be certain it is not a local wiring issue.

4. Charge the product overnight for at least 8 hours.

5. When you plug the charging cable into the speaker or headphones, is the connector stable, or can it be wiggled around? If it can be wiggled, this could indicate that the charging port has been damaged or come loose. Sometimes wiggling the connection restores charging power.

IMPORTANT: Some products such as Xtreme, Xtreme 2, Boombox, Partybox 100 & 300, GO+Play and the Onyx Studio series do not use USB charging. Instead, they have a specialized charger. Do not attempt to charge these products with other cables or chargers.

If none of these fixes the issue, it could be that the battery has died or is losing its capacity, or that the charging connector on your speaker is damaged. Please contact us so we can assist you. Be sure to mention that you have tried the steps in this Battery & Charging FAQ so that our agents do not ask you to repeat these steps.

The Mute+ATMOS combination button press to determine the Battery Status was originally designed for production line testing, not for consumer usage.  We determined that this testing method was inaccurate and began testing using specialized external equipment.  As of Software Version V21.13.11.80, the ability to check Battery Status inaccurately has been removed.

When charging the satellite speakers you can be confident that the Battery Status is 100% when the LED indicator goes  out.  As well, when the LED begins blinking red, you are at 20% and should recharge or plug in your speakers.
