does jbl extreme led display turns off while in battery mode?
Answered by JBL SupportThe battery LED indicator on the XTREME, once charged, should stop blinking and show five dots lit, stating full charge. However, if the unit is being used while plugged in, the battery indicator would not stop blinking as the battery still drains power while being charged. If the speaker is switched off when charging, the battery lights should shut off when fully charged.
