Why is my LightSaver Max charging gauge off when charging?

This will happen if the unit is not within its operating temperature range (35-115 F) and has shut down for battery safety, there is an issue with the input connection, or the battery has been drained below functional level. To determine if this is a low battery issue charge the LightSaver Max for several minutes (from solar, USB-C or 12V inputs) in a cool location.
