Water is resolved into hydrogen in the negative electrode (starts to evolve when approx.
90% fully charged) and oxygen in the positive electrode (starts to evolve when approx. 70% fully
charged) during charging. In the early years battery fail mostly because of dry out the evolved gas
cannot recombined again, so it required acid or water refill. The latest VRLA battery overcome this
disadvantage gas will be recombination and hydrogen generation controlled too .
Principle of oxygen recombination
Generally speaking, negative plates are designed to have more active material. The oxygen which is
generated from the positive electrode will travel through the separators to the negative electrode
to oxidize the Pb sohygrogen generation is controlled. This recombination process allows VRLA
batteries to have minimal water loss over years of operation making them essentially maintenance
free. No refilling is necessary .
The cathode plays a dual role in VRLA batteries .
1. The spongy lead of the plate reacts with oxygen generating from the anode and is
oxidized to lead oxide
.
The lead sulfate of the plate has to accept the electrons which are transferred
through the external circuit,react to spongy lead from lead sulfate
.
General specifications
It is recommended to use less than 4 strings in parallel connection.
Serial connections should be made first .
