One of the most important properties of lead–acid batteries is the capacity or the amount of energy stored in a battery (Ah). This is an important property for batteries used in stationary applications, for example, in photovoltaic systems as well as for automotive applications as the main power supply.
Another important performance factor for lead–acid batteries is self-discharge, a gradual reduction in the state of charge of a battery during storage or standby. The self-discharge takes place because of the tendency of battery reactions to proceed toward the discharged state, in the direction of exothermic change or toward the equilibrium.
Lead acid batteries typically have coulombic 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.
The service life of a lead–acid battery can in part be measured by the thickness of its positive plates. During charging and discharging, the lead on the plates gets gradually consumed and the sediment falls to the bottom. As a result, the measurement of the plate thickness can be an indication of how much battery life is left.
Similar with other types of batteries, high temperature will degrade cycle lifespan and discharge efficiency of lead-acid batteries, and may even cause fire or explosion issues under extreme circumstances.
Unbekanntes Schalterargument.) As you can see, the old law for lead-acid batteries “increase temperature by 10 °C and get half of the lifetime” is still true (although there are neither oxygen evolution than corrosion effects which affect this reduction in lifetime).
