Unlike the previously used lead calcium batteries, the sulfuric acid contained in batteries with fleece technology is not self-contained in the battery housing.
Instead, the sulfuric 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.
