Battery light is always red | SoundLink® Revolve Bluetooth® speaker

If you're using the charging cradle:

Try the following:

Disconnect and reconnect the speaker to the charging cradle.

The bottom of the speaker may not be connecting properly with the metal contacts on the charging cradle. Try removing the speaker and inspect the metal contacts. If you suspect the contacts may be dirty, disconnect the speaker and cradle from power, then clean the contacts using a cloth with a small amount of isopropyl alcohol.

When reconnecting the speaker, do your best to align the metal contacts on the bottom of the speaker with those on the charging cradle. This will ensure the speaker is sitting correctly in the cradle.

Bypass the charging cradle.

Disconnect the charging cable from the charging cradle then connect the cable directly to the speaker. If the speaker begins charging, there may be an issue with the cradle.

Make sure the charger is connected to power.

You should hear a confirmation tone once connected to power.

Reseat the USB charging cable.

If LED remains red while charging, unplug and re-plug the charging cable from the USB port.

Try a different USB cable.

Try connecting your product with a different USB cable to determine if there is an issue with the first cable.

Check if the connected power outlet is working.

When connected to power, your product plays a tone. If you plug in but don't hear a tone, try plugging in another device (i.e. a lamp) to the same power outlet to confirm the outlet works.
