It looks like the water level in one cell of my OE 12V battery is low. I can see the fluid in the other 5 cells, but not in one of them There are lines on the side for low and high level and the indicator explanation makes it sound like you can add water (blue for good, red for add water, black for dead) - something like that. But it looks like a Maintenance Free battery. I tried a little bit to unscrew a cap but it didn't move and I didn't get serious with it. I haven't load tested it but the voltage was 12.42 Volts over the weekend, so the cell isn't totally shot if the water is, in fact, low.
Has anyone ever added water to the original equipment battery?
