As the sulphuric acid or the electrolyte splits, sulfur ions become free-forming crystals. These sulfur ion crystals then stick to the battery's lead plates, thus forming lead sulfate crystals.
What is battery sulfaction?
Battery sulfaction refers to the accumulation of lead sulfate crystals on the plates of lead-acid batteries. It typically occurs during the discharge cycle when the sulfuric acid in the electrolyte reacts with the lead plates.
It typically occurs during the discharge cycle when the sulfuric acid in the electrolyte reacts with the lead plates. If the battery is not fully charged regularly, these sulfate crystals can harden, leading to irreversible damage.Sulfaction can be triggered by several factors:
How does sulfation affect a battery?
While sulfation affects the battery plates, corrosion attacks the terminals, and both can lead to complete battery failure if not addressed. Let's explore what causes these issues and how you can prevent them. What is Plate Sulfation? As a lead-acid battery discharges, small sulfate crystals of lead and sulfur form on your battery's plates.
Keeping the water level just enough to cover the plates ensures optimal battery function. Batteries degrade over time due to chemical changes, with acid deterioration being a key factor. One of the main consequences is sulfation, where sulfate crystals accumulate on the lead plates inside the battery.
Are lead-acid batteries sulfated?
All lead-acid batteries can suffer from sulfation during prolonged usage which is a normal part of an aging battery. That being said, certain types of lead-acid batteries are better than others. AGM batteries are the most resilient of the bunch.
Besides facilitating the chemical reaction, sulfuric acid also helps conduct electricity. It ensures electrons flow smoothly between the battery's terminals, which is essential for powering the car and starting the engine. Temperature plays a major role in battery performance.
