I have wet cell batteries in both house and engine compartments. A couple of them are hard to get to, so it would be easier if I had an auto-fill watering system similar to the link or picture. Has anyone used one of these units for 12v systems and if so, how well did they work? I see more choices in the 6V systems than the 12v, and the field narrows even more when attaching to 8D batteries.
Yes, I am aware that for less than $8K I can change over to AGMs, but my economic status prevents this. I feel compelled to continue to eat and pay the electric bill!!!
