The ideal discharge curve of a lead acid battery is on a flat discharge curve, the amount of current that the battery can deliver remain more or less constant for quite a while and then drop off rapidly when the limit of it capacity has been reach.
A lead acid battery consists of electrodes of lead oxide and lead are immersed in a solution of weak sulfuric acid. Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte.
Wide differences in cycle performance may be experienced with two types of deep cycle batteries and therefore the cycle life and DOD of various deep-cycle batteries should be compared. A lead acid battery consists of electrodes of lead oxide and lead are immersed in a solution of weak sulfuric acid.
The minimum open circuit voltage of a 12V flooded lead acid battery is around 12.1 volts, assuming 50% max depth of discharge. How much can you discharge a lead acid battery?
12V lead acid batteries are popular in solar power systems and other 12V electrical systems. They’re widely available and have a low upfront cost. Many car and marine batteries are 12V lead acid batteries. They are made by connecting six 2V lead acid cells in series.
Operating temperature of the battery has a profound effect on operating characteristics and the life of a lead-acid battery. Discharge capacity is increased at higher temperatures and decreased at lower temperatures. At higher temperatures, the fraction of theoretical capacity delivered during discharge increases.
For example, a lead-acid battery may provide just half the nominal capacity at 0° F. The operating temperatures of batteries are also different based on the type of battery you are working with. …
