T&T: AGM batteries

[Allen, Harris]

All batteries in Swan Song are AGM's so we have no need for venting

hydrogen, another very good safety feature IMHO.



Agm batteries will vent if case pressure exceeds 3 to 5 psi, that is why
they are known as VRLA batteries. At this point hydrogen gas is
released. For the case pressure to reach that point there must be
something very wrong with the charging equipment but the possibility of
the batteries venting must be taken into consideration!
