Bad Coach Battery

So I went and checked the coach batteries today to see if the water was ok in them. All checked out fine except for one was low. Started adding distilled water to it and the level was not rising, the water was leaking out the back. Must of froze at one point or another. Must be the original batteries from 2014.

Now do I get 4 new batteries now ? Or is there a way that I can take that one battery out for the winter and just leave the 3 others for the winter. Can just 3 batteries be run ?

I'd really like to take them all out so I can clean up the compartment, respray the black paint on the bottom and put in the battery mats I bought. Just not sure if it can go through the winter on 3 batteries or go for the 4 now. Just would want to protect the new ones for the winter.

I have always been told to replace all the batteries at the same time. I would in this case as you have to assume that all 4 were subjected to the same abuse.

Yes Phil that's what I've seen also. Replace them all at once. But seeing that basically the coach will not be used for the winter I was wondering if I could just take that cracked one out so it doesn't make more of a mess in the compartment and wire them so just the three are working for the winter. If that's the way it's been I'm sure way before I bought the coach it seems like it's been running the coach fine for lights and the fridge.
Sort of like a 3 legged dog, not as fast but gets there.

Then come spring I'd put all 4 batteries fresh with new.

Sorry Joe I assumed you were still using it. I don't see why you can't wait until spring to replace them. What's to protect? You will toss them in the spring right?

Yes just would have liked to clean up the mess in there. Not sure if the cracked battery will continue to leak as it gets heated up. Guess I could just let the coach go dead for the winter but was thinking of keeping it on support, keeping the fridge working, and having lights to flip on when ever we feel like going in and make believe we're at a CG.

Joe, I have attended a number of battery seminars concerning motor homes. I have always been told that you need to have an even number of batteries in place because you are making 12 volts from two 6 volt batteries, and then I believe they are in parallel (or maybe it was series). I also would not leave the "bad battery" in, as it will ruin the other battery. If I remember this correctly, batteries will seek the lowest level battery. You can get the remaining batteries tested and see what there condition is. I did at one time replace only one battery under warranty and then replaced the other three the next season. No problems since. Hopefully this helps! Craig

Craig makes a good point if they're 6-volt batteries. If that's the case, you can likely pull 2 batteries out.

There should not be a *need* for 4 batteries; especially if you have a way of charging them regularly.

Joe - Take the batteries out and clean and repaint NOW, The acid that leaked already has, and will continue to do damage. Wash with lots of water, apply baking soda and let it sit awhile, then fully flush again.

Joe if I remember correctly you purchased your unit preowned so my question is are the batteries original? If not how old are they.
The charging circuit will increase amperage to restore the weak battery/cell as such it will cook the other cells causing them to boil out. As others have said go buy a hydrometer and see what your specific gravity is of all the cells.

Wayne the batteries are Interstate. I'm assuming that they are original 2014. They are not punched out. Do you know what brand Berkshire puts in at factory ?
