Coach Battery Compartment

[CampClark]

I’m cleaning up the coach battery compartment and noticed some holes not sealed that’s apparently letting dirt and moisture in. Should I seal them or do they have to stay open for ventilation?Attachment 282026

In mine, I left the holes open for ventilation. It didn’t seem like a lead acid battery compartment should be tightly sealed.

Thanks. Two more thoughts. Maybe just seal the lower one? What about putting a piece of rubber material under the batteries to absorb bumps? I did find the battery strap in the compartment when I removed the batteries so I will be putting it on when I replace the batteries.

Like others that have posted questions when/after removing batteries……

I hope you took detailed photos before you started removing any connections.
This is suggested assuming everything was working satisfactorily before removing the batteries.

Lol I learned that lesson years ago.

Had gas tank in the trunk of a Ford , the spare tire sat in a depression made in to the top of the tank. Had that brown rusty water stain and a whole lot of grit.


Grit and dirt eventually ate pin holes into the gas tank.
Found this out after filling up and the spare tire started floating!


what's that got to do with a battery well...
dirt and grit in the compartment will eventually wear holes in the battery.
clean out the compartment


glue some rubber 1/2" strips to bottom of battery
(hot glue OR self adhesive rubber sheets cut them to size)

space strips so there is plenty of gaps for water to run out and to collect the gritty dirt

only has to be 1/8'' thick (or thicker if you can find)
rubber sheets or rolls of weather stripping can be bought at local hardware


PS glue strips to battery so can take out the battery leaving a clear space in the well.. Makes cleaning easier.

I cleaned up the metal and coated the compartment with a generous layer of flexseal. Followed that up with a critter prevention screen over the vent/drain hole. When I reinstalled my AGM’s I put a wood spacer between and in front(MH front) of the batts so that when the strap was tightened the batts would not move forward. Worked great for years.
