How Are the Cells of a Lead Acid Battery Connected in Parallel? The cells of a lead acid battery connect in parallel by linking the positive terminals of each cell together and the negative terminals together. This connection increases the total available current while maintaining the same voltage as a single cell.
Batteries, or rather battery packs can be designed to be use in parallel configurations by designing cells that "match" each other. "Matched" battery packs or arrays are built using cells that are manufactured to have small differences in specifications such as internal resistance and open circuit voltage so they have very little stray current

This experiment can be used as a class practical or demonstration. Students learn how to construct a simple lead–acid cell consisting of strips of lead and an electrolyte of dilute sulfuric acid. The cell should then be charged for different lengths of time, before being discharged through a light bulb.
The next phase of discharging is in the bulk or main part of the discharge. During this phase, most of the energy of the battery is discharged. For a lead acid battery, this happens in a relatively linear manner, with the voltage dropping in proportion to the Depth of Discharge, or inversely proportional to the State of Charge.
The lead acid battery is most commonly used in the power stations and substations because it has higher cell voltage and lower cost. The various parts of the lead acid battery are shown below. The container and the plates are the main part of the lead acid battery.
This experiment introduces the student to some of the electrical characteristics of a lead acid battery. Specifically, we will investigate: Charge and discharge curves - Lead-acid batteries have unique charge and discharge curves (voltage vs. time during charging and discharging). Amongst others, these curves can be used for:
Now to charge the Lead acid cell current in the opposite direction is applied, this way the chemical reaction is reversed and once again the +ve plate becomes Lead peroxide and the negative plate become pure lead, during the same process the electrolyte is also restored i.e electrolyte becomes sulfuric acid.
