Battery: Testing and Inspection
Sulphation
Sulphation
A battery will be completely discharged if it is left unattended for a long time and the specific gravity will become less than 1.100. This may result In
sulphation on the cell plates. To determine if a battery has been "sulphated", note its voltage and current when charging it. As shown In the figure, less
current and higher voltage may be observed in the initial stages of charging.
