Acid Stratification
An undesirable process in batteries where the heavy sulphuric acid settles in the lower part of the battery and the water on top.
This can be caused by incorrect charging and can be avoided by correct charging.
If the acid is stratified, chemical processes only take place in the lower part of the battery, the performance decreases and the battery fails within a very short time. It can aggravate plate corrosion, sulfation and the formation of battery sludge.
