Battery: Service Precautions
Sulphation
A battery (with specific gravity less than 1.100) will completely discharge when left unattended for a long period of time. This will result in sulphation
on the cell plates.
A sulphated battery may sometimes be brought back into service by a slow charge of 12 hours or more. A capacity test should be run after the battery is
charged to ensure the battery is not damaged.
