PROBLEM TO BE SOLVED: To provide an electronic apparatus and a secondary battery protection circuit capable of extending a period of time until a battery voltage reaches an over discharge zone depending on the status of use by a user.SOLUTION: The secondary battery has a function to prohibit discharging when the output voltage value on the battery cell lowers below a predetermined first voltage value. The secondary battery has a control unit that prohibit the secondary battery from supplying the electric power when the output voltage value on the battery cell reaches a second voltage value or lower, which is higher than the first voltage value. The control unit determines the second voltage value based on at least the output voltage value on the battery cell at a point when the electric power supply is terminated.SELECTED DRAWING: Figure 8 |
