Sump Pump Back Up Battery- adding water?

My back up battery is saying that I need to add distilled water. Where do I add it? I have a Watchdog back up battery.

    Unless it's a sealed battery, there should be a plastic cover you can pry up with a small screwdriver. You add distilled water in each cell just to the fill line (slight ring in the plastic inside, or the top of the notch inside the hole).

    What do you do with a sealed battery? I'm not seeing any openings to put water in.
