How to eliminate sulfation reaction in lead-acid batteries

How do you remove sulfation from a lead-acid battery?

Sulfation can be removed from a lead-acid battery by applying an overcharge to a fully charged battery using a regulated current of around 200mA for a period of roughly 24 hours. This process can be repeated if necessary, but it is important to monitor the battery closely during the process to prevent overheating or damage.

How does lead battery sulfation work?

Their sulfuric-acid electrolyte transfers a quantity of sulfate to the plates, and recovers it respectively during these alternating phases. Lead battery sulfation impedes the flow of electrical charges when discharging, until the battery is technically ‘flat’. However, sulfation need not be permanent.

How does sulfation affect a lead-acid battery?

In conclusion, sulfation is a common issue that affects lead-acid batteries. It occurs when the battery is left in a discharged state for an extended period, causing the lead sulfate to harden and become insoluble. This results in a significant reduction in the battery’s capacity and lifespan.

How to remove sulfation from a battery?

The best way to remove sulfation from a battery is to use a desulfator. A desulfator is a device that uses high-frequency pulses to break down the lead sulfate crystals on the battery plates. You can also try reconditioning the battery by using a battery charger that has a desulfation mode.

Can you loosen sulfate from a lead battery?

But it may be possible to loosen the sulfate by applying an ‘over charge’ for 24 hours, according to Battery University. In summary at this point: Lead-acid batteries may ‘hard’-sulfate if they do not recharge in a matter of days. This is why lead batteries in storage should ‘trickle charge’ to avoid this.

Can sulfation damage a battery?

Yes, sulfation can damage lead-acid batteries. It is the number one cause of early battery failure in lead-acid batteries. When lead sulfate crystals build up on the battery plates, they can reduce the battery’s ability to hold a charge, resulting in a shorter battery life. What are the signs of sulfation in a battery?
