The cycle life and capacity of a Li-ion battery are reduced if it is overcharged or in some cases over-discharged. Kise et al. measured the impedance at different temperatures of a Li-ion cell under its normal range of potential and tested the internal temperature of an overcharged cell. They did not indicate impedance growth while overcharging the battery.
When a battery has been subjected to deep discharge (commonly referred to as over-discharge), the amount of electricity which has been discharged is actually 1.5 to 2.0 times as great as the rated capacity of the battery. Consequently, a battery which has been over-discharged requires a longer charging period than normal.
All you can do is check the electrolyte and put it on a trickle charger. If this is the first time that it has been discharged, you should be able to fully charge the battery and continue using it, but every time it is discharged below that threshold of 10.5 volts, the damage is done.
Over Discharging Battery. manufacturer should specify cutoff voltages for various operating temperatures and discharge rates. Over discharge may cause difficulties in recharging the cell by increasing the battery''s internal resistance. Also, over discharging may cause lead to be precipitated in the separator and cause a short in the cell or

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
Renogy''s products, like many other lithium batteries, are susceptible to over-discharge, leading to potential issues like reduced battery life or the battery''s inability to hold a charge.This is a common problem faced by
Recovering an over-discharged LiFePO4 battery is possible to some extent by using a parallel charging board to connect it to a standard 3.2V LiFePO4 battery. However, this method only works if the battery''s voltage hovers around 3V post-over-discharge. Batteries with significantly lower voltages are beyond salvage due to irreparable damage to
Figure 1: Sleep mode of a lithium-ion battery. Some over-discharged batteries can be “boosted” to life again. Discard the pack if the voltage does not rise to a normal level within a minute while on boost. Do not boost lithium-based batteries back to life that have dwelled below 1.5V/cell for a week or longer. Copper shunts may have formed
Avoid leaving the battery fully discharged or fully charged for long periods. For storage, maintain an optimal charge level of 40% to 60%. The consequences of fully discharging include diminished power storage and an increased risk of battery failure. Over time, the ability of the battery to hold a charge decreases.

A lithium-ion battery (LIB) may experience overcharge or over-discharge when it is used in a battery pack because of capacity variation of different batteries in the pack and the difficulty of
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.
The risks of complete discharge include voltage drop and potential battery failure. A battery that is fully discharged may become unstable. This instability can lead to risks such as overheating or even leaking. To prevent this, it is crucial to monitor your battery levels regularly.
In order to operate lithium-batteries safely and optimize their life span, they should not be over-charged or deep discharged. What happens when a battery is over-charged? If neither the charger nor the protection circuit stops the charging process, then more and more energy enters the cell.
First you say "no, at all" — it's never safe to fully discharge. Then you go on to state that problems happen "during charging" — which is a different activity. 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.
Lithium-ion batteries contain chemical compounds that can degrade with deep discharges. When a battery is fully discharged, the voltage drops to a level that can cause irreversible damage to the electrodes. This damage reduces the battery's ability to hold and deliver a charge, leading to shortened overall lifespan.
No, it is not OK to have a Li-Ion deeply discharged at all. Here is why: When discharged below its safe low voltage (exact number different between manufacturers) some of the copper in the anode copper current collector (a part of the battery) can dissolve into the electrolyte.
