Lead–Acid Batteries
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. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.

Batteries | Free Full-Text | Heat Effects during the Operation of Lead-Acid Batteries …
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as "thermal runaway." This …
Self-discharge of Batteries: Causes, Mechanisms and Remedies
Abstract: Self-discharge1 of batteries is a natural, but nevertheless quite unwelcome phenomenon. Because ... In case of the lead-acid battery it may look more appropriate. Lead being less noble than
