Battery Terminal Cleaning

Don't forget the apron, long shirt or coveralls, heavy rubber gloves and FULL face and eye protection. Also if in doubt, check the ventilation.

Well Clifford, I can only go on my experience. Sorry to here about yours. Good Luck, TomC

I think the 118 degrees plus the charging is tough on the AGM I don't have good luck with the AGM batteries here but I never heard of a thermal runway before ?.

The guy told me they can catch fire so now they want their batteries well vented with air movement it kinda does away with the AGM features of the past.

I'll know next week if they give me any relief my cost on 6 of those suckers is 3 grand plus shipping and I need to redo the battery compartment which is not going to be a easy task

I been thinking about taking it to Larry and let him worry with it

Larry is finishing up Ben's Flx and an RTS and after that he says he has two more Flx's coming in, one is an unlimited funds corporate rig; no budget or time restraints.

Did Ben sell his Prevost yet ? Larry does such good work he is like getting a appointment with a good heart surgeon

I keep a spray bottle filled with a baking soda/water solution. I spray the terminals, wire brush them, and wash them off. I am sure that there are better chemicals available, but this works okay as long as they don't get to bad. If so, I repeat the process.

The one real problem I have is remembering to put on a pair of my special battery cleaning pants. If I don't, I can expect to be making a new pair.

I've used baking soda in years past but found it must be washed clean and coated with something oily or the soda just causes more corrosion.

It is also batt sudden death if any of that solution gets into the batt!

It's been my experience that the black coating forms only on the positive terminal and it is harder than hell. It's more an insulator than a conductor. I ran across some information that the coating is lead oxide, not lead sulfate.

It forms on the outside of lead posts from the post seal seeping a trace of electrolyte into the joint, which then oxidizes. You shouldn't find that on the stud type post. I also find that the age of the battery makes it worse.

Cliff, there were two group 27s in our coach when we bought it. Temperatures were getting up to 115 degrees when I tried charging them up. They had a case of thermal runaway. When they erupted, I just got well away from them for fear that they might explode.

After the excitement, there was not a trace of power in either battery.
