Most rechargeable batteries can be overloaded briefly, but this must be kept short. During a battery discharge test (lead acid 12v 190amp) 1 battery in a string of 40 has deteriorated so much that it is hating up a lot quicker than other battery''s in the string, for example the rest of the battery''s will be around 11,5v and this particular
Over Discharge Conditions. Typical rechargeable lithium cells can safely operate down to 2.75V/cell. However, when an unprotected lithium cell is discharged past the minimum voltage level you run the risk of damaging the cell and ultimately lead to degraded cycle-life, unstable voltage characteristics and swelling of cells from internal chemical reaction.

The self-discharge problem is especially bad for aqueous zinc batteries (AZBs), which are a type of rechargeable batteries that hold certain advantages over Li-ion batteries, such as in safety and environmental friendliness.
[7-13] Unfortunately, the inevitable parasitic reactions in rechargeable batteries always frustrate the real battery performance away from their initial designs due to irreversible self-discharge, [14, 15] which refers to the progress where a fully or partially charged battery gradually loses its initial stored capacity as self-discharge
When the battery discharges the externally stored power and the working voltage reaches a certain value, redischarging will cause the rechargeable battery to over-discharge. Excessive discharge of the battery will have a devastating
Rechargeable batteries lose stored energy when they''re not being used because an idle battery undergoes internal chemical reactions that slowly drain its energy. This “self-discharge” process can eventually consume active ingredients in the cathode, where the electron-spent lithium ions collect while the device is in use.

Irreversible Chemical Reactions: Over-discharging can cause some of the chemical materials to degrade. Increased Cycle Count: Each deep discharge accelerates the wear on the battery's capacity. Conclusion: Avoiding full discharge helps maintain the battery's capacity and prolongs its useful life. 5. Reduced Charging Efficiency
Safety Concerns Over-discharging lithium batteries not only affects their lifespan but also introduces safety risks. When the battery voltage gets too low, it may lead to overheating or swelling, which can be dangerous. In extreme cases, the battery could catch fire or even explode, especially in high-power batteries like the 21700.
Once the charger enters constant voltage mode it is important to ensure the charge does not exceed the maximum level allowed to avoid exposing battery is overcharging conditions as it can cause excessive internal temperature rise and lead to premature failure. Typical rechargeable lithium ion battery cells can safely operate down to 2.75V/cell.
The battery will not be able to store 100% of its power when it is recharged. Worse still, batteries that have not been charged for a long time may not be able to hold a charge and enter “sleep mode”, where their voltage cannot be restored without professional intervention.
As a result, the voltage in the cell rises – this is known as over-charging. On the one hand, this is harmful to the battery and bad for its life span. On the other hand, it can pose a safety risk for the user. The excess energy leads to heat generation. “In the worst case, this can lead to a so-called 'thermal runaway'.
When lithium batteries are fully discharged, the chemical reactions inside the battery can change, directly affecting its capacity. For example, if a 21700 battery is over-discharged, its usable energy will be significantly reduced, leading to shorter usage time, and it may not be able to fully recharge to its original capacity.
