Battery Hold Down Corrosion

<< < (2/2)

LarryNCarolynShirk:
Joe,

You may try velcro to hold the straps together, or just eliminate them.  We have 8 batteries without tie downs and no problems bouncing out ot the tray.  Our '98 Patriot did not have tie downs either.

Gerald Farris:
Joel is right about AGM batteries not being a cost effective solution for his problem, as it would probably be around $1,000.00 repair and he probably still has around 4 years left on his OEM batteries.  

If you have not done so yet I would thoroughly clean the problem parts that are reuseble and soak them in a paste of baking soda and water to neutralize all acid before coating them with a good protectant like the Permatex paint.

If you are having to water your batteries too often (every 3-4 weeks) you are either overcharging the batteries or you need better battery caps. Either one will cause excess gasing and therefore corrosion.

If the only problem you are having is with the hold-downs on the batteries, check carefully to see if they are needed. If the batteries are mounted in a snug tray that goes up about half of their hieght like my Marquis, the hold-downs are not needed and may have been only added for liability protection. However if the batteries are not snug and in a deep tray the hold-downs are neccessary.

Our coach does not have the tie downs and the snug fit tray is 3/4 inch angle. We have over 100,000 miles without a problem.

We went with http://www.eastpenn-deka.com/ AGM after having to rebuild the rack and hearing of 8 plus year users and still going strong. We got about 5 years out of the Trojan wet cells and they did very well using little water the first three then getting pretty gasey the last two years of use.  We store under a pole barn plugged in for our dehumidifier in FL.  Hope our AGM's work like the reports we have gotten.

I have had Lifeline AGM's for 3 years and I just love them. They have much more power than my old Interstate batteries, recharge faster, and there is never any need to add water or clean up corrosion. To me, that makes them worth their cost. I just replaced my starting batteries with Optima AGM's and now I never have to check batteries for water or corrosion again.

Bill White:
I just put the water miser caps on new batteries that was just installed.  I will report the results later, but I was having a lot of corrosion problems too.  It's the outgassing of the batteries as they charge and it is very corrosive.  If the water miser caps return the gases back into the batteries as water, then that should fix the problem.
