The following are some common causes and results of deterioration of a lead acid battery: Overcharging If a battery is charged in excess of what is required, the following harmful effects will occur: A gas is formed which will tend to scrub the active material from the plates.
A lead acid battery loses water due to overcharging, which causes the electrolyte to break down into hydrogen and oxygen gasses that are expelled through the venting system. The concentration of sulfuric acid in the electrolyte (typically 38%) naturally increases in the process.
A fast screening method: for evaluating water loss in flooded lead acid batteries was set up and the Tafel parameters for both linear sweep voltammetry and gas analysis tests, determined at 60 °C for water consumption, correlated well with the concentration of Te contaminant, to be considered responsible for the increased water consumption.
Lead acid batteries are considered a mixture containing sulfuric acid, an extremely hazardous substance (EHS) and other non-EHS hazardous chemicals such as lead, lead oxide and lead sulfate. To report a lead acid battery, information on battery weight should be listed on the Safety Data Sheet (SDS).
To calculate the weight of a lead acid battery, multiply the chemical component percentage by the weight of the whole mixture in pounds. For example, using the information from the Safety Data Sheet (SDS): 'The total weight of the battery is 200 pounds. Lead makes up 60% of the total weight, and sulfuric acid makes up 35% of the total weight. Calculate the weight of lead: 60% of 200 pounds = 120 pounds. Calculate the weight of sulfuric acid: 35% of 200 pounds = 70 pounds'.
Different aging processes rates of flooded lead–acid batteries (FLAB) depend strongly on the operational condition, yet the difficult to predict presence of certain additives or contaminants could prompt or anticipate the aging.

Non-intrusive monitoring of the state-of-charge of sealed lead-acid batteries using wire-wound coils is described. Coils were attached to the plastic case of the batteries, adjacent to the negative end plate, and excited using ac current at 10 kHz.As the batteries were cycled, the inductance of the coils tracked the change in metallic content of the end plates.
Moreover, the CB3 battery water loss reached 36.1 g after 400 cycles.
