Unlike the previously used lead calcium batteries, the sulphuric acid contained in batteries with fleece technology is not
self-contained in the battery housing.
Instead, the sulphuric acid is 100 % bound up in glass fibre fleece mats (separators). Thus, no acid can escape if the
battery housing is damaged. In addition, the AGM battery is sealed gas-tight. This is possible because the gases are
converted back into water as a result of the separator permeability.
Brief description of components
An AGM battery can be recognized by its black housing and the lack of a so-called "Magic Eye".
