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.
Yes, it is dangerous to attempt to charge a deeply discharged Lithium battery. Most Lithium charger ICs measure each cell's voltage when charging begins and if the voltage is below a minimum of 2.5V to 3.0V it attempts a charge at a very low current . If the voltage does not rise then the charger IC stops charging and alerts an alarm.
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.
Full eruptions should be avoided because they put additional strain on the battery. Studies have shown that a lithium-ion battery regularly discharged to 50% before recharging will have a longer lifespan and may retain up to 1,500-2,500 cycles, compared to just 500-1,000 processes if regularly fully discharged.
Battery Chemistry Stress: Lithium-ion batteries have a finite number of charge cycles, and constantly keeping them at a high charge (close to 100%) can stress the battery chemistry, leading to reduced capacity and a shorter overall lifespan.
Article quickly disappeared from ZDNet. Yes, lithium-ion cells undergo unwanted chemical reactions when discharged below 3 V, causing their internal resistance to be permanently and significantly raised. Their capacity will suffer as well, meaning that they won't accept the same amount of charge anymore.
