How rechargeable batteries, charging, and discharging cycles work

The Discharge of the lead-acid battery causes the formation of lead sulfate (PbSO 4) crystals at both the positive electrode (cathode) and the negative electrode (anode), and release electrons due to the change in valence charge of the lead. This formation of lead sulfate uses sulfate from sulfuric acid which is an electrolyte in the battery.

Lead–Acid Batteries

A lead–acid battery cannot remain at the peak voltage for more than 48 h or it will sustain damage. The voltage must be lowered to typically between 2.25 and 2.27 V. A common way to keep lead–acid battery charged is to apply a so-called float charge to 2.15 V.

How Does Temperature Affect Lead Acid Batteries?

Lead-acid batteries will accept more current if the temperature is increased and if we accept that the normal end of life is due to corrosion of the grids then the life will be halved if the temperature increases by 10ºC because the current is double for every 10ºC increase in temperature.
