Cutoff voltage
VOLTAGE AT WHICH A BATTERY IS CONSIDERED FULLY DISCHARGED, BEYOND WHICH FURTHER DISCHARGE COULD CAUSE HARM
Cut-off voltage; Low-voltage-cutoff
In electronics, the cut-off voltage is the voltage at which a battery is considered fully discharged, beyond which further discharge could cause harm. Some electronic devices, such as cell phones, will automatically shut down when the cut-off voltage has been reached.
