I got a couple of rather large gel-cell batteries the other day (the largest is a 12V 24ah) but it turns out they weren't such a great find. Neither will take a charge; with the charger connected, neither battery will draw so much as a single milliamp. Both batteries have a number of little round covers; underneath the covers are small rubber caps covering a hole. I noted that when I removed one of the rubber caps, there was a small inrush of air as if there was a vacuum inside. My guess is that both batteries have "dried up", possibly from lack of use. Is it as simple as adding water, and if so, exactly how much and what kind (distilled, tap, etc) should be used? Thanks for any advice.
