Recovery of discarded sulfated lead-acid batteries

During the normal discharge of a lead-acid battery, lead sulfate forms on the plates of battery. When recharged, the lead sulfates are converted to the soft spongy lead. When this material fails to release from the battery''s plates, it begins to harden and crystallize and then sulfated. Sulfation is the prime cause of a battery loosing the

Behavior of the Lead Acid Battery after the Rest Period

A discharge voltage versus time curve of a lead acid battery contains three regions: the first region contains a voltage increase of about 10-20 mV, lasting a few minutes; the linear region is the most important having the longer time; during the third (hyperbolic) region, the voltage decreases more rapidly. In the third region, it is defined

6 FAQs about [Recovery voltage of lead-acid battery after discharge]

Do open circuit voltage and energy recovery of lead acid batteries affect health?

It was demonstrated that the magnitudes of open circuit voltage and energy recovery of lead acid battery have relationships with the health status of the battery which if well exploited, can lead to innovations in the science of state of health determination for lead acid batteries.

How does a lead acid battery work?

The actual process is dependent on the type of battery we are talking about. In a lead acid battery, The cell voltage will rise somewhat every time the discharge is stopped. This is due to the diffusion of the acid from the main body of electrolyte into the plates, resulting in an increased concentration in the plates.

Why are lead acid batteries kept at open circuit voltage for 800 Min?

The batteries were chosen to be kept at open circuit voltage for 800 min because some works have shown that for lead acid batteries, the state of charge can be derived at open circuit voltage when the battery is disconnected from the load for at least two hours and this OCV is linearly proportional to the Depth of Discharge (DOD) .

How do you know if a lead acid battery is healthy?

It was noticed that the open circuit voltage of a lead acid battery after solicitation and their energy recovered after a discharge can be used to decipher how healthy a battery is. Battery B registered an OCV variation of 0.02 V while D registered an OCV variation of 0.03 V.

What is the OCV of a battery after discharge?

After the end of discharge, battery A's OCV goes back to 12.27 V. For battery B, the voltage increases to 13.36 V and takes the longest time to discharge before attaining the cut off voltage compared to all the batteries tested and its OCV after discharge was 12.64 V.

Why is recovery energy different in a battery?

The differences in recovery energy is therefore be an indication of the state of heath of the battery. The higher the recovery time at the same recovery discharge rate, the healthier the battery is likely to be.
