Defects of Lead Acid
Battery
- Corrosion-
formation of insulating layer in the electrodes
- Sedimentation-
formation of sediments at the bottom (corrected using distilled water)
- Sulphation-
deposition of hard layer of lead sulphate on the plates on batteries idle
for a long time
- Buckling-
bending of cell plates caused by charging and discharging for a long time
Trickle
Charging-charging with low current for a long time to revive a
sulphated battery
