5 PzV and PzV-BS lead-acid batteries with sealed armour
plated cells
5.1 Description
PzV batteries are sealed batteries with fixed electrolytes, to which no water can be
added over the entire lifespan of the battery. Relief valves are used as plugs which
are destroyed when opened. During operation the same safety requirements apply to
the sealed batteries as for batteries with liquid electrolyte. This is to avoid electric
shock, explosion of the electrolyte charging gases or hazardous electrolyte burns if
the cell vessels are destroyed.
Z PzV batteries are low gassing, but not gassing-free.
Electrolyte
The electrolyte is sulphuric acid which is fixed in gel. The density of the electrolyte
cannot be measured.
