Learn MoreSulfation occurs when lead sulfate crystals form on the battery's lead plates, impairing its ability to hold and deliver a charge. This process can significantly reduce the lifespan and efficiency of a battery. Understanding the causes of sulfation and how to prevent it is crucial for maintaining battery health and performance.
Here are some tips on how to fix a sulfated battery: 1. Remove the battery from your device and clean it with a dry cloth. 2. Apply a sulfate-free battery cleaner to the battery and scrub it with a brush. 3. Reinstall the battery into your device and turn it on. 4. If the battery still doesn't work, you may need to replace it.
A sulfated battery is a type of lead-acid battery that has been treated with sulfur to prevent oxidative degradation. Sulfation creates an electrochemical barrier that can protect lead plates from external damage, including pollution and excessive moisture.
While these can sometimes be salvaged, it is unlikely that restoration is possible. Reversible sulfation can often be corrected by an overcharge to an already fully charged battery in a regulated current of about 200mA. The battery terminal voltage can rise to 2.50 and 2.66V/cell (15 and 16V on a 12V monoblock) for about 24 hours.
Worse yet, the sulfate crystals act as an electrical insulator, increasing the battery's internal resistance (keep this in mind when we cover recharging). At this point, the battery acid has given up most of its supply of sulfate and hydrogen.
The physical effect of this resonance introduced to the plates is what causes the lead sulfate crystals to break apart. The desulfation process means that the internal resistance of the battery cells has decreased. This is a very good thing, it means that the battery can hold more charge.
