Try not to stress the computer while charging it, e.g. by doing a heavy video encode at the same time. Deep discharge and heat are both much worse for the battery than having it fully charged, though that can damage it too. If you can keep the battery between 30%-80% charge, and below 90˚F/32˚C as much as possible, it will last longer.
Is It Bad to Fully Discharge a Lithium-Ion Battery? Consequences
The underlying reasons for avoiding full discharge include battery chemistry and cell structure. Lithium-ion batteries contain multiple cells that rely on a stable range of voltage for optimal performance. When a cell discharges fully, it may enter a condition known as deep discharge. Deep discharge can cause lithium to plate on the anode and

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.
What happens to a battery if it is fully discharged?
The self discharge of the cells will slowly but surely drain them further until they are so low that they can''t be safely recharged. At that point the battery can only be scrapped. You would need to fully discharge the battery to the point where the cars stops driving and leave it sitting for months to actually do this though so it''s not very
Battery Charging and Discharging Parameters
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is

Depth of Discharge (DoD): The depth of discharge refers to how much of the battery''s capacity is used. A full discharge (0% DoD) can be harmful, while partial discharges (20-80% DoD) are less damaging and can enhance battery longevity. Studies suggest that limiting full discharges preserves battery health.

They are also known to lose their capacities marginally with each cycle. Li-ion batteries are designed to retain at least 80% of their capacity for 300-500 cycles. And the
Should you fully discharge a Li-Ion battery on first use?
So to prevent this, the charging circuitry will intentionally brick the battery (prevent you from ever recharging it) if it determines the charge level is too low. If you discharge the battery and leave it sitting, the gradual self-discharge can drop the battery''s charge level past this threshold, resulting in a permanently bricked battery.

The most adequate method to do a full discharge (100% to a minimum of 3%) consists of the following procedure: Fully charge the battery to its maximum capacity (100%); Fully charge the battery to its maximum capacity (100%); Let the battery "rest" fully charged for 2 hours or more in order to cool down from the charging process.
Can I Fully Drain a NiMH Battery? Myths, Safe Discharging, and
No, you should not fully discharge a NiMH battery as it may cause damage. Fully discharging a nickel-metal hydride (NiMH) battery can lead to a condition called deep discharge, which can damage the battery''s cells. NiMH batteries ideally should not be discharged below a certain voltage, typically around 1.0 volts per cell.
Can A Deep Cycle Battery Be Fully Discharged? Risks, Recovery,
If users regularly fully discharge the battery, they may only achieve 300 or fewer cycles. Another factor is the depth of discharge (DoD). A shallow discharge, or a lower DoD, improves battery longevity. For instance, a deep cycle battery that operates between 50% to 80% DoD will usually last longer than one that drains completely to 0%.
