Nighthawk M6 Pro, Model MR6500 connect or not when not using for extended period of time

[aleibel]

I just purchased the M6 Pro for our RV and it worked fine.  We will not be traveling for a couple of months and will not be using it during that period of time.  Is better to leave it connected to power or to keep it disconnected when not using it?  If is better to have it connected should one take the battery out or leave it in?

If you're not planning on using it at all, power it off and pull the battery.
