About a year and a half ago I installed the semi-automatic battery water refill system on my electric cart. Because of renters, I thought it would be easier to do, which it is, BUT
The kit comes with a refill hose that has a squeeze bulb and attaches to a water input nozzle which in turns feeds water to all the cells at once. Sounds great huh? When the squeeze bulb won't take any more squeezing, thats the indication that the water level is up to par.
WRONG!
The squeeze bulb contains two check valves that prevent the water from going the wrong way. The check valves are metal and they rust and guess what they stick shut giving you the indication that the sytem doesn't need any water. This happened to me and also to my neighbor. This scenario can ruin your batteries. I can't emphasize enough the importance of maintaining the proper water level in your batteries.
Hope this saves someone some bucks

Ouch! Now that's good info to know. I was thinking of installing one in my cart but I just decided to keep water level the old fashioned way.
Thanks for the warning,

Good information, a few dealers said these systems were trouble prone and could cause battery problems by not filling them correctly.

I didn't get one and have been filling my batteries with special water battery filler (about$15 or so from dealer) that you put into the battery hole and its supposed to stop filling the battery at the right level. Well thats almost right but I kept trying to get the last drops of water in and over filled my batteries. They looked oj after I filled them but after running the cart some they leak over my garage and driveway a bit. So perhaps the message here is you need to be careful with whatever method you use and if you use a manual battery filler stop when it first indicates its done filling.

Regardless of all the gadgets in the world, there's just something about doing things "old school" that gives peace of mind....
