Coach battery box questions

[LovemyClassC]

I am a proud owner of a Thor MC Class C Freedom ELite. I recently purchased a battery box and tried it out today. It would not fit through the coach angle frame underneath the step. It would fit if I cut out the top of the frame, which I will not do. It is a hard plastic box and is not flexible. I will return it. The battery frame is showing no corrosive deterioration at this time. So, the question is what does everyone else do to safely house the battery and protect the coach steel frame any residual splashes?

I set my batteries right down into the battery area and didn't use a box...

this type of box might serve a good use for trailers with exposed hitch-mounted battery placement - though I think most RVs with battery boxes under or within the RVs storage areas or steps are already designed for the batteries and don't need additional 'cover'. Batteries actually 'want' air flow - it's better for them.

While installing a master battery cutoff switch I added plastic battery trays and further protected the steel with Flex Seal.

I like the response below using a battery tray. I found them on the internet this morning. I simply worry about when I take hygrometer battery test and the electrolytic splashes out of the battery fill hole and gets on my painted steel frame. The corrosive action will likely take 10 years to cause any issue but.....I am a relentless person. Thank you for your response.

I agree with you. I did like the response for the battery tray though. Just worry about splashes while doing a hygrometer test.

This is a great idea. I happened to find them on the internet this morning. $8.00 or so fix each battery. I just worry about splashes while I am doing a hygrometer test or charging the battery when they are in the tray and using a on shore charger. Thank you for the great solution. Have a good day.

First, I will paint the framework if it shows any corrosion, naval jelly the rust spots and paint according to those instructions, as needed.
Then I just smear a thin layer of axle grease on the metal with a paper towel, or my fingers.

Once the batteries are in, I use some sort of de-oxidizer grease on, and over, the connections.

That usually works for me, it just attracts dust, and maybe a bit dirty next battery removal.
At least the metal part has kept its integrity.

This is just how I tackle it.
Kind of old school!
