What is the purpose of the baffle plates in a lead-acid battery's electrolyte system?

The purpose of the baffle plates in a lead-acid battery's electrolyte system is to maintain electrolyte level. Baffle plates serve to create a defined space within the battery that helps control the movement of the electrolyte, reducing the chance of stratification, which is the separation of different concentrations of electrolyte. By promoting uniform circulation within the battery, these plates ensure that the electrolyte remains at an optimal level throughout the operational life of the battery. This uniformity is crucial for maintaining consistent performance during discharge and charging cycles, as it ensures that all active material in the plates is adequately submerged and functioning properly.

This explanation highlights the important role of baffle plates in facilitating the proper functioning and longevity of lead-acid batteries, particularly in terms of electrolyte management.
