Self-discharge is a phenomenon in batteries.
Reduced voltage: A low self-discharge battery shows significantly lower voltage than its rated capacity. For instance, a fully charged nickel-metal hydride (NiMH) battery should read about 1.2 volts per cell but may read less if it is experiencing self-discharge issues.
Battery self-discharge rate. As soon as a battery is manufactured, it immediately begins to lose its charge—it discharges its energy.

During self-discharge, the charged lithium-ion battery loses stored energy even when not in use. For example, an EV that sits for a month or more may not run due to low battery voltage and charge. “ Self-discharge is a phenomenon experienced by all rechargeable electrochemical devices,” said Zonghai Chen, an Argonne senior chemist.
Self-discharge refers to the process in which a battery loses charge, even when it''s not in use or connected to any device. It''s an inherent characteristic present in all batteries and is dictated by internal chemical reactions.
