Why this innovation matters to your AGM Batteries
AGM/VRLA Formation
The formation process for AGM or VRLA
batteries really begins with the filling process. The introduction of electrolyte results in
very high heat generation over a short period
of time, thus thermal management is critical.
Heat generation can be counteracted by
chilling the electrolyte and putting the filled
battery into a chilled water bath.
Fill-to-Form Processing
Fuse Connection Box
One fuse per each polarity per circuit
to protect batteries and rectifier
connection cable in case of short
circuit conditions
Conveniently located straight
forward rectifier interface
The time gap between electrolyte filling and
initiation of the formation process is more
important than might be realized. The longer
the delay between fill and form the more
lead sulfate is formed. This facilitates the
formation process, but it also increases the
resistance of the unformed plates, as lead
sulfate is an insulator.
Longer stand times after filling can also
aggravate the conditions that can initiate
dendrite shorts by allowing lead sulfate to
slowly dissolve and diffuse into the separator.
Subsequently the batteries are put onto
formation as quickly as possible after fill.
