The means of over-discharge and over-charge can make
Finally you claim that a "deeply discharged battery have higher self-discharge", which at this point even my uneducated brain has to rule out as just plain illogical. An empty battery should have nothing left to discharge, i.e., zero self-discharge. $endgroup$ –
This practice helps ensure optimal battery performance over time. What Are the Specific Effects of Full Discharge on Car Battery Health? The specific effects of full discharge on car battery health can be detrimental. Fully draining a car battery may lead to reduced lifespan, diminished capacity, and potential damage to its cells.

Overcharging and over-discharging are two common issues that can significantly impact a lithium battery''s lifespan and safety. This article explores what these
When a battery experiences over-discharge, it can suffer from irreversible capacity loss, meaning it will never regain its full storage capacity. This reduces the device''s runtime and requires more frequent recharging.
Over-discharging is easier to occur at low temperatures. In this paper, the degradation characteristics were investigated by discharging to 2.75-0 V at 0°C and discharging at constant voltage for 0 and 2 hours, respectively.
The Battery University defines over discharging as the discharge of a battery below its safe voltage limit, leading to chemical changes that may impair its functionality and safety. Several factors contribute to over discharging a battery. These include extended periods of use without recharging, faulty battery management systems, and poor
The results indicate that, when a battery is over-charged, the battery''s surface temperature increases first because of ohmic heat, and after that, internal short-circuit occurs, resulting in the battery experiencing thermal runaway. However, in the case of over-discharge, the battery''s surface temperature rise is limited.
During discharge, the chemical reactions within the battery cause electrons to flow from the negative electrode to the positive electrode through an external circuit, generating electrical current to power the load. Overcharge and Overdischarge. Overcharge: Overcharging happens when a battery is charged beyond its maximum recommended voltage or
According to the curves, it is clear that the over-discharge process could be divided into three main stages. Stage (a) is the initial over-discharge stage as described above, where the temperature increases at a high rate of 413 °C A −1 h −1. Hereafter, the battery entered the severe over-discharge stage consisting of stages (b) and (c).
With the popularity of lithium-ion batteries, especially the widespread use of battery packs, the phenomenon of over-discharge may be common. To gain a better insight into over-discharge behavior, an experimental study is carried out in the present work to investigate the impact of current rate, i.e. cycle rate, charge rate and discharge rate on the degradation

discharge.1–5 An LIB may experience overcharge or over-discharge when it is used in a battery pack because of the capacity variation of different batteries in the pack and the difficulty in maintaining identical SOC of every single battery. The battery in the pack will inevitably experience overcharge or over-discharge to a certain degree
CAPACITY — The total amount of electrochemical energy a battery can store and deliver to an external circuit. It is normally expressed in terms of Ah or runtime at a desired discharge rate. The nominal or nameplate capacity of a battery is specified as the number of Amp-Hrs or runtime that a conditioned battery should deliver at a specific discharge rate, temperature and cutoff voltage

Since LVP has a lower discharge voltage plateau (1.85–1.60 V and 1.97–1.79 V) (Fig. 8 d), the termination potential of the anode can be limited to a lower level (<3.4 V vs Li/Li +) during the process of over-discharge, thereby avoiding Cu dissolution and improving the capacity retention rate of the battery after a series of over-discharge operations from 49.55% to 95.91%.

Due to the inconsistencies among cells within the battery pack and the potential faults in battery management system, intermittent overcharging occurs during the long-term operation of cells. However, the impact of such occurrences on battery capacity and reliability has not been fully revealed.
However, frequent deep discharges will lead to a gradual decrease in the capacity of the lithium battery. The active substances in the battery will be irreversibly lost during deep discharge, resulting in lower battery capacity and shorter cycle life. Want to extend the battery life of your cell phone?
When the discharge voltage falls below the cut-off voltage specified by the manufacturer (usually 2.5V or 2.8V), the battery is considered over-discharged. Frequent over-discharge accelerates battery aging, shortens battery life, and can cause the battery to generate excess gas and heat internally, leading to swelling or leakage.
Overcharging occurs when a lithium battery's charging voltage exceeds its maximum cut-off voltage, typically between 4.2 and 4.4 volts (for cell phone lithium-ion batteries). This can lead to changes in the structure of the cathode material inside the battery, resulting in a loss of total capacity.
Batteries are increasingly subjected to the conditions of overdischarge as greater numbers of cells are connected in series for a system requiring high voltage, such as electric vehicles 14. Therefore, overdischarge and its impact on batteries must be investigated.
Cause of failure during overcharging is uncovered by nondestructive observation. Failure prediction methods are proposed by monitoring three characteristics. Due to the inconsistencies among cells within the battery pack and the potential faults in battery management system, intermittent overcharging occurs during the long-term operation of cells.
