Just put the above quik fill kit on my batteries this evening. Very quick, very easy and SO much better than what I've dealt with. The one I bought is for class 24-31 12v batteries.
Backdrop is I have a 2014 Cougar High Country. It has the enclosed cowl which we liked for the appearance. Didn't really think about battery mtce. Since I keep it plugged in nearly all the time I have to check them. That required pulling the cowl, pulling the LP tanks, pulling the battery box covers and then digging back in the recess to check the cells, then taking the little water bucket and filling the cells. WAY big pain in the tail and something that just made me put off doing it.
I read about the quik fill system on this forum or another one. Looked VERY interesting to me because it would save me so much trouble so bought it. Well, after my install and initial little fill up I'm thinking...."where has my head been all this time???"
Just throwing this out there because we have lots of members dealing with battery mtce. (or not) and this might be the "cat's meow) for some. Here is the link. I will attach 2 because you have to have the pump assembly to use in conjunction with the quik fill assembly - a little pricey but I was happy when I got it installed..... the fill kit....
