6 FAQs about [Will sulfuric acid in lead-acid batteries be lost ]

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 does sulfuric acid work in a lead-acid battery?

Under normal conditions, sulfuric acid in the electrolyte solution is absorbed into the lead plates as the battery discharges power. It is then released back into the electrolyte solution as the battery charges. The only electrolyte that can be used in a lead-acid battery is sulfuric acid.

Do lead batteries 'hard' sulfate?

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. Undercharging a lead battery by 10% reduces its capacity by a similar factor. The longer a battery is in storage, the greater the chances of ‘hard’ sulfation.

What happens if a lead acid battery runs away?

Under normal conditions, constant voltage charging of lead–acid batteries shows a decrease in current approaching an asymptotic limit at a very low current. In the case of the thermal runaway, the current can rise to the limit of the power supply delivering the current. The Joule heating can boil the electrolyte resulting in a venting of steam.

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?

What causes a battery to sulfate?

The sulfation process is accelerated if the battery is left in a discharged state for a prolonged time; or is not properly and regularly equalized. This leads to the development of large crystals that reduce the battery’s active material, decreasing the battery’s capacity and performance.
