Battery water fill systems.

Looking for pros and cons on different systems to add water to my house batteries.


Right now I'm looking at the "Water My Battery" system. This is what one friend has and he gave me a demonstration. I liked it but I'd like to get a system that was a little less expensive.

I could not figure out a way to edit my above post so I'll just add the link I wanted to insert in the original post:

Wow, I guess I am low class and junk yard simple in my solution. I set a gallon of distilled water up on a step stool higher than what the batteries set. Then using some surgical tubing suck the water into the tubing allowing it to siphon downward into the batteries one cell at a time.

Once a cell is filled I pinch the water flow off with my fingers on the tube and move on to the next cell.

A flash light helps depending on lighting conditions.

It seems to me that FR could have been more customer-considerate had they installed AGM batteries originally. The percent price increase on the MH would have been negligible.
We added 2 more 6V batteries after installing solar. Monitoring water in 18 cells is a PITA.
These recommendations are very helpful; I'll be going with something more automated.

Similar to jonjen I use a turkey baster. Suck it full of distilled water. Works and my baster was a buck.

slightly off topic- but not-
Why are you going through so much water in your batteries? If your boiling the hell out of them- and need water constantly you may be over charging- to trying to charge your batteries to fast.

Same thing on my Berkshire. Seems every time I turn around I'm adding more water to the batteries.

You’ve more electronics than my 2016 XL I’m thinking, but I only have to add about 1/4 gallon total (between four six volt batteries) about every 2 1/2 months. It’s the corrosive fumes I don’t like more so than the filling.

Out of the factory the charger is set to a pretty high rate. (MAX ie 80A in my case). Reducing that decreases boil off, but does increase charging time. If you do any boon docking and count on generator to keep your batteries up that won't work. Adjust as necessary. I put 1-2 gallons a year in mine.

I use Water My Battery. Squeeze the bulb a few times, batteries full, disconnect, done. No drips, no runs, no mess.

Thanks everyone for your input. Yes, I've been putting water in batteries for close to 65 years. And I've used many of the ways mentioned here. But I know I'm a person that will do better maintenance if it is easy. And I see I'm not the only one thinking a maintenance system is a good idea.

I appreciate you guys with the Pro Fill comments. I'm probably going to go with the Water My Battery system, I like the clear tubes and the white floats.

I think for most people- they could cut their charge rate in 1/2- ( I have max at 45 amps) then if needed- raise the charge rate - its not that hard to do- Its a lot easier then adding water all the time. I have used less than a gallon in 3 years.

Oscarvan and dave-g - you mentioned how easy it is to do. Can you tell me how it's done. Also, could you recommend a setting. (The only boon docking we do is just overnight.)

Thanks for the reminder. Will change mine to 50% or 50 amps.

Lowered mine, but the lowest setting is 60 amps, which is what I selected. We're on the road all over the west so I'll see how it goes. Thanks for the info.
