battery water

[Emmel]

I guess if it is really a 'maintenance free' it is sealed and requires no water. If it is not maintenacce free and needs water, the easiest way is to use a nasal spray bottle. When empty, clean it out, use di water, and you can squeeze a little into each cell as needed. However, if your cells are empty, do not add water and seek out the leak, probably needing a replacement battery. (hows that for an edit)
