What is Battery Sulfation?
Sulfation happens inside Lead–acid batteries when the electrolyte starts to break down. As the sulphuric acid (electrolyte) splits up, sulfur ions become free forming crystals. These sulfur ion crystals then stick to the lead plates of the battery, thus forming lead sulfate crystals. With time the crystals grow in size and become hard, covering …

Discharging a lead-acid battery. Discharging refers to when a battery is in use, giving power to some device (though a battery will also discharge naturally even if it''s not used, known as self-discharge).. The sulphuric acid has a chemical reaction with the positive (Lead Dioxide) plate, which creates Oxygen and Hydrogen ions, which makes water; and …
Battery Sulfation
What is battery sulfation? When lead-acid batteries are in a discharged state for any length of time, sulfation will build and will decrease the battery''s capacity.

What is Sulfation and How Does it Affect My Battery?
With more time, sulfation progresses and a battery may require a greater charge. The final stage is when the battery is simply not able to be charged at all. While lack of regular use certainly contributes to the build-up of sulfation, it isn''t true that batteries won''t develop the sulfation if always kept fully charged.
