Self-discharge is a phenomenon in batteries. Self-discharge decreases the shelf life of batteries and causes them to have less than a full charge when actually put to use. How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors.

Wang et al. [15] proposed the use of a Gaussian curve to fit the nonlinear relationship between voltage and battery discharge, constructed a discharge prediction model for lithium batteries, and indirectly predicted the self-discharge power; however, the prediction model parameters must be artificially set, which requires a large amount of parameter adjustment time.

Customer ServiceSelf Discharge Is Ongoing in An Idle Battery. A battery continues to naturally drain energy, whether on a shelf or in an idle device. This means the charge will not last as long as it should, when a user decides to draw on its power. However, the actual rate of battery self-discharge depends on several factors.
Customer ServiceBattery self-discharge is caused by the internal reactions in a battery that reduce the energy stored without any connection with an external circuit. In other words, the battery loses the energy stored in it by itself due to its internal behaviour even when the connected application is not demanding any energy. Since the state-of-charge (SoC

How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors.
Self-discharge can significantly limit the shelf life of batteries. The rate of self-discharge can be influenced by the ambient temperature, state of charge of the battery, battery construction, charging current, and other factors. Primary batteries tend to have lower self-discharge rates compared with rechargeable chemistries.
