I've never tried this. But I believe mineral oil will help. Thank you for the amount to put. So what kind of mineral oil. Brand? And where to buy?

Doesn't matter. Lots of us have gotten it at Wal*Mart. That's where I got mine.

X2 on Walmart. In the pharmacy dept. 16 oz for a couple of bucks.

Thanks everyone for the reply's.
I appreciate it!

Thinking about adding mineral oil house batteries but have a question. We have had the coach for 6 months and I recently added, maybe, 2 oz of water. That's 2 oz total for both 6 volt batteries.
So, the question is, do I just wait until each cell needs water before adding the mineral oil or should I take some out in order to add the mineral oil now?

Woodburner, A battery does not "breath" it only exhales. Hydrogen gas is generated and released when a battery is charged. This Hydrogen bubble rises to the top and burst splashing either battery acid or mineral oil into and out of the battery cell chamber. It is your choice in the one.

I use the mineral oil in both my boat and RV batteries, two reasons less corrosion and less water added.

I am no expert but I have been around a long time.

Down to -10 deg F, no problem

Down to -10 F IF, the battery is fully charged.
When a battery runs down, the Electrolyte turns to Water which will freeze at 32F resulting in plate distortion and a ruined battery. Has nothing to do with using Mineral
Oil or not.
Electrolyte = H2So4 (hydrogen sulphide) in the charged state. Discharged it becomes H20, Water. The S(sulphur) combines with the lead plates to become PBS04. (Lead Sulphate)
Apply the charging current and the Sulphur is driven back out of the plates to combine with the Water and we again have a charged battery with Electrolyte. Of course, during this process, Hydrogen Gas is being generated. Don't be causing sparks around the batteries when they are charging. Big Boom.....

There, you ask the Time of Day and I have to tell how the Watch works........

Dennis, your my kind of guy, I love the details but in my younger years it nearly worked me to death.

When I would explain something in detail I would wind up either assisting or taking the lead on some "project".

Now it is just the basic facts and no explanation.

Your facts are spot on so tag, your the project manager.

Me thinks you may be younger than I. I really, really enjoy my senior years.

RealTime,
thank you for the vote of confidence. I love retirement also (dennis45 tells all). I ran a crew of field servicemen (as many as 25) so babysitting and training were the norm every day.

Dennis, good explanation of the charge/discharge cycle in a battery. Just for accuracy, the electrolyte H2SO4 is sulfuric acid, not hydrogen sulphide (actually spelled sulfide). H2S is hydrogen sulfide and is a poisonous gas naturally occurring in some producing sour gas wells, and will kill you dead if you breathe it. That was what Red Adair and his crew were fighting in the blowout depicted in the old John Wayne movie "He11 Fighters".

Good catch, had a brain fart as I was squeezing the stuff out of my old head. I have been in the Gas Compression Ind. for a long time and familiar with H2S.
