Design
The AGM battery differs from the conventional lead calcium battery as follows:
-
Larger plates:
Larger plates provide for a 25 % higher power density.
-
Separators made of glass fibre fleece:
These provide for up to 3 times higher cycle reliability.
This in turn improves cold starting performance, current consumption and service life.
-
Gas-tight housing with pressure relief valve (see also mode of operation):
The cell plugs are welded and cannot be opened.
-
Acid bound up in the glass fibre fleece:
The acid is not as previously self-contained in the housing, but 100 % bound up in the glass fibre fleece. This
provides increased protection against acid leakage and thus represents a reduced risk to the environment.
Mode of operation
The AGM battery differs from conventional batteries in its non-polluting and substance-retaining behaviour during
charging.
