Are you saying battery voltage has been removed for a period of time? When that happens, sometimes there are modules that have to relearn or be reprogrammed. Battery has a full charge and connections all good. I'd check voltage and grounds for computer and everything. With instrument cluster, sometimes you can disconnect then reconnect and the cluster might reset? Did you check for applicable trouble codes? Note the code below, there is more than one possible code. You can see the possible causes listed.
