even though no detailed study has been performed
yet concerning compression in gelled-electrolyte
batteries, one can assume that compression is also an issue,
as gel VRLA may also suffer from poor contact between the
immobilised electrolyte and the plates, when battery is
ageing and gel is drying out due to water loss. In that case,
the springiness of the Amersil separator might be highly
beneficial to maintain plate–electrolyte contact. This important
aspect has to be further evaluated.
