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. The discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid.

The positive active material is formed electrochemically from a cured plate, and influences the performance of the lead-acid battery. The electrolyte consists of a sulfuric acid solution, and as the battery discharges, the electrodes are converted into lead sulfate, which reverses when the battery is charged.
The disadvantage of this battery chemistry is that it is very sensitive to deep cycling compared to other battery systems, and due to the high density of lead, the specific energy of the batteries is quite low. Charging a lead acid battery system is slow, and it can take up to 16 hours for a full charge.
