A lead-acid battery is designed to last a finite period. It cannot last forever. Such sustained high temperatures will cause the water in the electrolyte to evaporate. 2. Electrolyte Loss. Batteries evaporate over time
AI Customer ServiceThis is because the chemical reaction that takes place in the battery can cause water to evaporate, which can lead to a loss of electrolyte solution and a decrease in battery

AI Customer ServiceA 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.
However, in many applications, batteries are experiencing relatively long periods of open-circuit stand. Water loss by “self-discharge electrolysis”, that is oxygen evolution at the positive plates, and hydrogen evolution at the negative plates, may then represent an important part of total water loss .
Nevertheless, positive grid corrosion is probably still the most frequent, general cause of lead–acid battery failure, especially in prominent applications, such as for instance in automotive (SLI) batteries and in stand-by batteries. Pictures, as shown in Fig. 1 taken during post-mortem inspection, are familiar to every battery technician.
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.
Electrolyte stratification is another common failure mode for lead-acid batteries. It is considered to be most severe in flooded batteries, much less prominent in AGM batteries and not significant at all in gelled batteries due to the immobilized electrolyte , , .
Valve-regulated batteries often fail as a result of negative active mass sulfation, or water loss. For each battery design, and type of use, there is usually a characteristic, dominant aging mechanism, determining the achievable service life. Temperature has a strong influence on aging.
