Yes the batteries are getting older to where they are using more water. Just getting to a PITN to hunch over and see the level as the water goes in. I have one of those watering cans posted by Dakota98 and still I think I want to go to the next level.
If I eventually give in and get new batteries I still want the watering system. Either way I am going to stick with wet-cell.
MEX, I assume the poisoning of the plates is part of normal aging. Any way to reverse?
Looked at the Pro-Fill brand... seemed like a lower quality consumer item.
