If the battery of your SRS-BTS50 Bluetooth® speaker won't charge, check the following to try to resolve the issue:

• Make sure the supplied AC adaptor is securely plugged into a working AC wall outlet.
  • Try a different AC wall outlet.
• Try to charge a different device to make sure there's no problem with the AC adaptor.
• Reset your device.
  • Press the RESET button on the left side of your device with a thin object (like a small pin).

  

Other Things to Consider

• Charging time varies depending on conditions of use of the battery.
• Charge your device in the ambient temperature between 41 °F - 95 °F (5 °C - 35 °C).
• Your device will get warm during charging. This is not a malfunction.
• Even if you don't intend to use your device for a long time, charge the battery to its full capacity once every six months to maintain its performance.
• If you don't use your device for a long time, it may take longer to charge the battery.
• If the life of the built-in rechargeable battery becomes extremely short, repair may be required.
• Avoid exposure to extreme temperatures, direct sunlight, moisture, sand, dust, or mechanical shock. Never leave your device in a car parked in the sun.

If the battery still won't charge, repair may be required.
