As mentioned -older chargers or cheaper with no floating circuit will boil your battery dry over the long time.
Even battery maintainers fail occasionally, so leaving one on permanently brings some risk.
My experience is that nothing beats pulling battery clamp as even disconnecting all appliances on the panels, leaves potential for current leaks on the cables.
Disconnected battery will hold the charge for 6-8 months.
I would not leave a battery sitting for 6-8 mos... 10% loss of capacity per month along with sulfating which causes a loss of spec. capacity....
If you store the battery and use a tender you need to make sure that the battery is FULLY charged, measuring the Specific Gravity with a hydrometer to make absolutely sure it is.
I leave my camper plugged in all the time when at home. I hate to remove my batteries for any reason. I now have AGM (s) and have no reason to even check connections.
