Part 3. Why is it bad to fully discharge a lithium-ion battery? 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.
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'.
Risk of deep discharge: If a battery is left fully discharged for an extended period, it can enter a state of deep discharge. This makes recharging difficult and sometimes impossible.
