摘要： A lithium ion battery is provided with an overvoltage switch (12) and an overvoltage control circuit (14). The overvoltage control circuit causes the overvoltage switch to open, thus disconnecting the battery from a charger, upon the battery voltage reaching a first predetermined level when charged by a charger not designed to charge a lithium ion battery. However, when the battery is connected to an appropriately designed charger, the battery receives an input signal through an input terminal (24) which causes the overvoltage control circuit to open the overvoltage switch at a higher second predetermined level, should the appropriately designed charger fail to enter voltage regulation when the battery voltage reaches the first predetermined level.
