Sorry, there was a problem. Please try again later.PLEASE NOTE: This lamp will function while the USB charging cable is plugged into a power source OR on its own internal battery. When using on battery power and the light starts to dim, this indicates that the internal battery needs to be recharged. The RED charging indicator in the back will turn off when the lamp is fully charged. Yes per Ottlite's instructions the red light should turn off when the Lithium Ion Battery is fully charged. You may want to consider returning the lamp for exchange or refund. Best regards, Ottlite Customer Service PH#800/842-8848 (M-F, 9am-5pm EST).
