Almost all RV's have a small, poorly vented battery box with 4 GC2 batteries. We see corrosion all the time. When we replace batteries, we use zinc coated copper terminals and apply a thin layer of grease with a toothbrush to every exposed portion of the connectors. This simple step, with the occasional reapplication, keeps all terminals as fresh as the day installed for many years. I am speaking from experience of hundreds of installations.

Yes, you can build sealed battery boxes and add vent pipes, fans, whatever, but battery terminals and battery cables installed in a confined box will have far more problems with terminal corrosion due to more concentrated forms of gasses and a mist of acid moisture that will settle on all surfaces. We have been called in to repair off-grid systems that used battery boxes only a few years old that had battery cable ends and battery terminals almost totally dissolved, yet, we have the same type batteries and cables installed in larger well-ventilated battery rooms that you could eat off of the floor 10 years later. I say that battery boxes should be a last resort and used only when there is no other way, and then you better make sure there are multiple sources of adequate ventilation air.
