What Is a Sulfated Battery?


When you check a lead-acid battery, do you sometimes notice large blue crystals gathered on them? You’re looking at the visible effects of sulfation on your battery. But what is a sulfated battery, and how do you prevent it? Keep reading to learn how to slow down this process.

What Is a Sulfated Battery?

Sulfation is a common problem with lead-acid batteries. In short, sulfation is a build-up of lead sulfate crystals on the battery plates. These light blue crystals building up are a natural part of the battery’s lifespan, but certain conditions speed up the chemical reactions. Overcharging your lead-acid batteries or storing them in heated areas will speed up the sulfation process.

What does Sulfation Do?

Sulfation impedes the chemical to electrical conversion in the battery. This process can result in many adverse side effects on your battery, such as longer charging times, difficulty holding a charge, and a noticeably weaker amount of power going to your devices.

How Do You Prevent It?

While sulfation is a natural part of a battery’s lifespan, proper care and attention can slightly lengthen your usage of the battery. However, this is inevitable, so moving to a lithium-ion battery is a much better solution. Lithium batteries require zero maintenance and don’t have any sulfate issues.

Now that you know what a sulfated battery is, you can properly address your battery’s state. The principal risks of sulfation come from the natural chemical processes within lead-acid batteries, but substitutes like large lithium battery packs do not have these chemical problems. BigBattery, for example, has you covered with products and services for all your power needs.
