AGM/VRLA Formation

The formation process for AGM or VRLA batteries really begins with the filling pro-cess. 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

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.

The new Digatron/Firing Circuits AGM/VRLA Water Bath

ensures fill-to-form processing times less than 15 minutes.
