Anybody have experience with these battery filling devices?   Either boat or RV??

The batteries on my rig are impossible to check without unhooking and removing the batteries from the tray. Might be better if I replaced some of the parallel cables with with longer ones, but still............

I have a local Basspro but no CampingWorld, so that's why that reference.

Some designs use a reservoir for water but with the jostling on the road that looks like disaster waiting to happen to me.

Thanks, L. G.

My opinions only:

I wouldn't consider an 'Automatic' battery watering system. I've had them and all had problems after a while (you still have to check reservoir water level). And they don't do a thing to assist in the periodic specific gravity checking.
Better to get longer cables so the batteries extend further, which allows water level checks, filling and Hydrometer usage.

Had the parts ordered from CW until I tried to check out and it was backorderd.

Tried the dealer I bought my PC from and he had a inclusive kit with everything at roughly $40 bucks cheaper so I purchased it - 3 years old new stock. I just got it put on and I filled the batteries (new) and I think I am going to like it a lot, let you know in a month or so if it stands up to me and acid.

P.S. Basspro had it in the catalog/online, not on the store shelf though, at substantially more than Camping World +shi.  They still wanted shi to bring it to the store, such a deal.

Well it's been a month + and just charged the batteries.  Then filled with water, in about 2 minutes or less. Took longer to get the fill bulb out of the toolkit than it did to fill (old age, didn't remember where I put it).  Considering how hard it used to be to do the same job in basically an afternoon, the $60 bucks for the fill kit is heaven.  No spills, no leaks, no acid all over, no corrosion, greatest thing for this type installation.
I believe I am going to like it alot.
