A friend of mine thinks I'm nuts. He leaves batteries on the floor all the time. Usually they are OK but I notice he is buying a new battery at least once a year.
Do what you like but what does it cost to put your battery on a scrap of wood?
Or, if you want to prove me wrong leave your battery on the floor with no charger or battery tender for a month and see what happens.
I have a big heavy battery that I only take when I'm boondocking, because the the battery box in the Argosy will only take a grp24 and running my CPAP all night on an inverter would be hard on the house battery, so I trip over this big sucker when boondocking.
When not traveling it sits on the concrete garage floor. It's never been dead when it's time to go, and it sits there for months at a time between boondocking trips.
