Battery Compartment

[Bob Denman]

Thanks...
I was imagining that you'd have to call Boeing, and give them the secret password.

Boeshield is e everywhere a round here. Home depot lowes etc
I mainly use it on my salt water fishing reels before spoiling them up with line. When Boeshield drys it leaves a waxy type coating that prevents the salt from corroding the spool

Idk how well it would work on batteries. I think I'd go with a product made for that purpose

I have a few cans from years back by Pennzoil called Marine Protector Spray. Sounds like a very similar product. I would spray the entire powerhead of the outboard (salt water use mostly) and all the electrical connections and it would last for ever. It left a sorta waxy, very lightly tacky surface but great barrier. I forgot, until this thread started, I still have 6 cans of it downstairs.

Gonna give it a try. For 20 bucks hope it works.

I had similar issues to what you stated, over and over. Pulled batteries, wire brushed and repainted compartment twice. Used plastic batterie holders and it still remained a continual challenge beyond just making sure the water levels stayed full
FINALLY bit the bullet and spent the money for Trojan AGM batteries which are rated to hold up in the high heat of very south Texas in the summer. Have had these batteries since April and have not had a worry since. In the end it was worth it to go this route for me

On my last coach the battery compartment was under the entry steps and made of a composite material that didn't corrode. The batteries didn't require monthly cleaning either. Any suggestions?

My battery compartment is under the steps of my Thor and I believe that there is almost 0 airflow in there and my battery corrosion was pretty bad too. It has looked pretty good after I cleaned it up because I leave it open now when I'm not using the vehicle. There's quite a bit of wiring in there because I am using two 6 V golf cart batteries in series.

It's only been a week since I did the batteries using the Boeshield T-9 spray as the last step. I checked today and the compartment and batteries look immaculate. According to their website one can use this stuff on anything that is susceptible to corrosion. This stuff may be my new best friend, thanks for the suggestion. I was going to try Fluid Film, but nobody suggested it as a possible solution.

Congratulations!

When I had four six volt batteries I cleaned the battery compartment every time I checked the water. Mixed several table spoons of soda to half gallon water and sprayed it on and around the batteries. Let it set 5 or 10 minutes then hosed it down with plain water. Flooded the floor of the compartment real good with water. Let dry thoroughly and coated compartment with wd40. Had that motorhome 15 years and was nearly rust free in the compartment.

Our Ford Chassis on my 2018 was manufactured in early 2017. The coach was built in April of 2017, delivered to the dealer in May of 2017 then was titled as a 2018. So at a minimum our batteries are two years old as well. Battery warranties start on the date of sale not the date of mfgr.
Our last coach I changed out a pair of wet cell deep cycle batteries about every couple years. As we spent a good deal of time in National Parks without power I wanted fresh batteries. Wet cell batteries are going to off gas during charging. I "de fuzz" 2 to 3 times a year. I also put a piece of rubber floor mat under the batteries. The last coach (Gulfstream) the sulfuric acid ate a hole in the bottom of the battery tray, it happens on all brands.

All comments are useless when it comes to the Thor Vegas.Battery compartment on Ford chassis is impossible to get to. Terrible location as your battery may die and what is one spoke to do ?

I also do the old shade-tree mechanic's baking soda thing. Been doing it with my vehicles, boats, etc., since I was a teenager. Mix about a heaping table spoon full in maybe 12 oz of water in an old drink bottle, then pour it over and around the batteries. It will foam up where ever it finds traces of corrosion and/or battery acid residue. Let it sit for maybe 5 min. then hose off. I also keep a coating of dielectric grease on the terminals and cable connections to help control corrosion. I only have to do this twice a year to keep everything clean and corrosion free.

[lwmcguire]

Don't forget WD-40 is a Dielectric

Before changing to AGM I used regular terminal protectant available in blue or red from several manufacturers

Forms a plastic like barrier

Most new vehicles now come with AGM, at least all mine have, so it just makes sense that it should at least be an option for house batteries

I’ve used it on my motorcycle engine cases and it does the job (though it will yellow a bit over time). In a battery compartment that shouldn’t matter.

I have used boeshield in a plane I had also. It is one of the best corrosion preventative around as it dries ,it does not absorb water . It should be used on inside of aluminum panels and floor boards . I'm glad you reminded me ,I have some in my shed. I used a garden sprayer with a home made set of extension tubes to do my plane. It was used in military planes for years. Will stay on anything it is sprayed on

Just sent another explanation about my battery problem

Another old mechanic's trick for battery corrosion is to stick a penny on top of the battery-the corrosion collects there first. Just "change" it out (no pun intended) every couple of months.

Zinc is an excellent sacrificial anode for sure

Question: How o you stick it to the battery?
would a layer of adhesive between the penny and the battery keep it from doing it's intended job?

How about posting the link to it for us...

I've done this for years also. A very small drop of gear oil or bearing grease will hold it in place. It works!!
