Self-discharge
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. [1] 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. [2]

Self-discharge of Batteries: Causes, Mechanisms and Remedies
Self-discharge of batteries is a natural, but nevertheless quite unwelcome phenomenon. Because it is driven in its various forms by the same thermodynamic forces as the discharge during intended ...
Self-Discharge Rates in Lithium-Ion Batteries: How They Affect …
Self-discharge refers to the phenomenon where a battery loses its charge over time, even when it is not connected to a load or charger. All batteries experience some level of self-discharge, but the rate at which it occurs can vary significantly among different types of batteries. For lithium-ion batteries, the self-discharge rate is generally low compared to other …

Introduction to DJI Intelligent Flight Battery Auto-Discharging Rules
Battery Auto-Discharging Function (Controlled Self-Discharge): The battery is actively controlled to discharge to a preset battery level within a specified time, using intelligent programming based on the battery''s normal self-discharge. For example, to prevent swelling, the DJI Mavic 3 intelligent flight battery automatically discharges to 96% of the battery level when idle for three …
Myth or Fact: Lithium-ion Batteries Self-Discharge …
What''s interesting about self-discharge is that it is non-linear with time. It means that a given battery''s self-discharge rate will change with the passage of time. The rate of self-discharge is also heavily dependent on temperature. The …
Understanding self-discharge of a Lithium-ion battery
Since the state-of-charge (SoC) is directly linked to the battery''s open-circuit voltage (OCV), self-discharge leads to a reduction of the SoC, which leads to the reduction of the OCV of the battery. Self-discharge is undeniable, and it happens in every type of system (battery) that stores energy. However, the speed at which the self ...
The truth about battery self discharge-what you need to know
All batteries will self-discharge, meaning they will slowly lose power over time even when not in use. The rate at which this happens varies depending on the type of battery, with some types losing power much faster than others. For example, lead-acid batteries typically have a self-discharge rate of around 20% per month.

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.
⊳ Battery self-discharge
The rate of self-discharge depends on the ambient temperature, the acid/mass ratio, battery type and battery technology. At temperatures above +55°C, the self-discharge is significantly increased. These temperatures are sometimes reached or even exceeded in storage rooms during hot summers. The same applies to batteries installed in the vehicle, especially in the …
