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.
Heat generation is a crucial factor for lithium-ion batteries during the charge and discharge process, which can trigger serious safety issue such as fire hazard and explosion. Over-discharge is a common inducement which can result in not only heat generation effect, but electrode and electrolyte failure.
Therefore, overdischarge and its impact on batteries must be investigated. Several previous studies have cast light on the overdischarge mechanisms of lithium-ion batteries 9, 15, 16, 17. The anode potential increases abnormally during overdischarge; thus, the Cu current collector of the cell is oxidized to Cu 2+ 9, 14.
