The battery status is read by the power connection to the unit. If there is power to the unit and you are able to get some readings than it soulds like there could be a permenant memeory issue which contains the programming to read battery levels as well as LPG. Without knowing if this is a newly installed unit or an older unit it is hard to say what may have caiused this lose if that is the issue. I recommend contacting the technical staff at Garnet, their # is 1-877-668-7813 to further diagnose the issue.
