New battery watering systems?

I have to replace a set of group 27 batteries, but I am looking into adding a watering system, like the Qwik Fill, to service the batteries. It's a little expensive ($60), but it will allow me to water the batteries through out the year without having to un-connect and remove, water and re-install each time. But then, I'm upgrading the charging system to a 3-stage to stop boiling the batteries dry too!

The fill system is hand pumped from a water source, into the battery cap that has a float stop that only allows it to fill to the top of the fill line. It runs in parallel, so each cell get the water until it's full. The fill lines could be routed into my battery boxes from inside, so I could add water at any point while I'm in the AS.

Has anyone had experience with this system?

No experience with it on a trailer, but I've got it on our sailboat. I run 4 golf cart batteries and access is tough. I've had the quick fill for 6 months or so and really like it. I have the one fill line running up to a locker where I can drop it in my water container and pump it. Works just fine.

cheers,
steve

Not needed?

Hi, I think you sort-of answered your own question. If your batteries need water that much, or that often, then they are cooked, overcharged, or bad.

It sounds like an interesting solution to the problem of watering the batteries. I would be concerned that any of the floats could fail and either flood or dry a cell. A simpler, but more costly solution would be to replace the batteries with AGMs. That would eliminate the need to ever add water.

I agree with the AGM solution. I spent the money and love them. They last longer, and no water to add.

Steve,

I'm curious.

Where and how do you mount batteries on a sailboat? Are they on gimbals to prevent spillage?

Thanks for the input, but the AGM solution is good but expensive. The flooded cell are cheap but require lots of maintenance and watering is one I can solve,plus the 3 stage charger to keep them charged up. I'll let you know if I can get the 5-7 years out of this new set of batteries. I think I'll also use a battery monitor and a battery circuit switch to isolate the batteries in storage. Is this good money chasing a bad battery?????????

I think the watering system is best for coaches that use large, multi batteries that have poor access, like sailboats. I think this product started in the marine industry and has overlapped into other markets. I saw them used for many years in watering large electric batteries hi-lows in manufacturing.

I have several months to think this one out before the AS is unthawed in the spring.

is it ok for the vent/fillers to vent into the trailer?

Hi Mark,

No they're not gimballed. Normal heel isn't enough to cause spillage issues. Main concern is just strength of the battery box to keep them from moving. Ours are mounted in one big box, aft of the engine, just under the cockpit. That fill system really works well for me. The batteries don't use a lot of water, but they do use water. When they're hard to get to, I just don't check them as often as I should.

cheers,
steve

Ricky, I don't think they vent through the fill tube, but it's a good question to ask the manufacture about, as he's right here in Michigan.

I think the hydrogen explosion issue is waaay overstated. In normal use, you don't produce that much. The problem comes when you have a dead battery and you've hooked up another vehicle--the charging rate is very high in the first minute or so and the area under the hood is confined, plus you get a spark right at the point where you remove the jump cable. So if you've hooked up right to the battery terminal, the spark is in just the right place.

These three conditions just don't usually happen in an RV. There's almost zero explosion danger inside an RV in normal charge/discharge operations and there is no physiological danger from the gas.

You really have to work hard to blow the top off an battery, yet people seem to do it several times a year. Murphy is very proud...

No water needed for batteries after two years of use!

I replaced the battery burner in my AS after the first set of batteries went bad, with the new 4 stage converter, I haven't needed to add any water to the new set of batteries in two years. A big change after having to water the batteries three to four times a year with the old converter. So, I'm no longer looking into watering systems now that I have a good charging system in the AS. And I'm hopping that the new batteries will last a few more years too.

For storage, I use a good trickle charger to keep them alive without charging. This may be the best of battery maintenance!??

Zep,
I grew up with a guy who lost his vision because a battery blew up in his face.
He was legally blind though he could see a little, could not drive though.
Never got into the particulars about how stupid he was, just know there is some danger.

Hi from Ga. . . can't find info on these automatic watering deals. I have 4 batteries and manually watching water levels is gonna get tedious. OK,OK, I know, I'm not the smartest guy here, but maybe someone could point me in the right direction ? ? please ?, thanks and regards, Craig
