When testing lead-acid batteries at the 8-hour or other discharge rates, the temperature of the electrolyte during discharge should not exceed 115°F (46°C). When testing NiCd batteries at the 5-hour or other discharge rates, the temperature of the electrolyte during discharge should not exceed 104°F (40°C).
The final selection of lead-acid battery is performed using an optimization algorithm of differential evolution. Using the optimization process, the new battery selection method includes the technical sizing criteria of the lead-acid battery, reliability of operation with maintenance, operational safety, and cost analysis.
A Lead Acid Battery consists of the following things, we can see it in the below image: A Lead Acid Battery consists of Plates, Separator, and Electrolyte, Hard Plastic with a hard rubber case. In the batteries, the plates are of two types, positive and negative. The positive one consists of Lead dioxide and negative one consists of Sponge Lead.
In a functional lead-acid battery, the ratio of acid to water should remain close to 35:65. You can use a hydrometer to analyze the precise ratio. In optimal conditions, a lead-acid battery should have anywhere between 4.8 M to 5.3 M sulfuric acid concentration for every liter of water. How do you properly refill a battery with acid?
A cost analysis was also carried out, which took into consideration maintenance and procurement costs, as well as the costs of the related air conditioning that keeps the prescribed temperature and ventilates the battery room. The impact is shown of selecting a lead-acid battery on the battery room’s operating safety when charging.
Figure 7: Discharge curve comparison of Lithium-ion and Lead-Acid battery As we can see, a lithium-ion battery tends to maintain a constant output voltage throughout its discharge, but a lead-acid battery loses voltage practically linearly and more quickly.
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.

Lead acid batteries consist of flat lead plates immersed in a pool of electrolytes. The electrolyte consists of water and sulfuric acid. The size of the battery plates and the amount of electrolyte determines the amount of charge lead acid batteries can store or how many hours of use. Water is a vital part of how a lead battery functions.
Neutralize the Battery Acid . Pour the neutralizing liquid into the glass container.
