Batteries serviced

[Horsedoc]

With the huge amount of heat we have had this spring and summer in the South, we have traveled very little since January. The rig stays plugged in to 30 amp with occasional short drives to keep the tires healthy. I figured it was time to take a look at at the house batteries. I had two gallons of distilled water waiting in the fridge where I kept it stored. There are 6 six volt batteries that are relatively easy to get to but hard to get water in unless you put it slowly with a small siphon hose (1/4 inch)
I found the same acid level in all the batteries at about the same height- close to the top of the plates. An hour and 2.25 gallons of water I am finished. I washed a small amount of corrosion off of a couple of connections. I am trying to find a coating that is a spray on, red in color, that we used on a previous coach. Never had any corrosion with that but I cannot remember the name. What do you guys use?

I am cheap. A large gob of Vaseline does the same. Looks ugly, but effective ! Corrosion is a chemical reaction with oxygen (air). Block the air and no corrosion !

Excessive corrosion around a battery post is often a sign that the gases in the battery are leaking past the seal between the post and the case. Typical on older batteries.

I use NOCO NCP-2 Battery Corrosion Preventative Spray, Part #A-202. It is red colored and works very well.

I used the Permatex spray and it worked perfect. And I use the Deka bulb type battery filler. It has a flexible "snout" and it's easy to wiggle into tight spots and doesn't make a mess.
