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.
Common problems with lithium-ion batteries include rapid discharge, failure to charge, unexpected shutdowns, and battery drain in idle devices. These issues can relate to energy-demanding apps, damaged ports, or flawed batteries.
Frequently discharging a lithium-ion battery to low levels can lead to reduced cycle life. Studies by the Battery University (2021) indicate that keeping the discharge level above 20% can extend battery lifespan significantly. Cell Damage: Cell damage can occur in lithium-ion batteries when the cells are allowed to fully discharge.
Fully discharging a lithium-ion battery can harm it for a variety of reasons: Voltage drops below safe levels: Lithium-ion batteries have a safe operating voltage range, typically between 3.0V and 4.2V per cell. Dropping below 3.0V can cause internal damage, leading to capacity loss or even rendering the battery unusable.
Lithium-ion batteries degrade when fully discharged. This degradation happens because deep discharging stresses the internal chemistry. The battery’s capacity reduces after repeated full discharges. Manufacturers recommend keeping the battery charge between 20% and 80% for optimal health.
If your Li-ion battery is damaged, or you suspect it is damaged, do not charge it. We can’t stress this enough. Attempting to charge a battery that has been damaged puts it at high risk of electrical overload and thermal runaway. Left to charge, it could explode.

The charge controller completed charging, having completed bulk, then absorption at default 14.2v and went onto float at 13.5v which is default too. I then shortly disconnected the battery from the solar charger and the weird thing is the voltage instantly dropped from 13.5v to 12.8v. No loads connected during charging or afterwards.
