Replacement battery pack with built-in charging circuitry and power connector, and AC adapter for reading charging status of replacement battery pack
First Claim
1. A replacement battery pack for an electronic device, the replacement battery pack comprising:
- a power storage section having a secondary battery;
a power input section having at least one power connector for receiving electric power for charging the secondary battery while powering an electronic device;
a power output/input section comprising a single terminal functioning as having an output terminal for receiving electric power from the power input section and for supplying the electric power to the electronic device when the single terminal is connected to a connector of the electronic device, and functioning as an input terminal for for charging the secondary battery by the electric power from the power input section when the single terminal is connected to the connector of the electronic device and for charging the secondary battery when the single terminal is connected to an external power source while the single output terminal is disconnected from the connector of the electronic device; and
an input power switch circuit for selectively inputting electric power to the power output/input section either from the power input section when the electric power is available therefrom or from the power storage section when the electric power is unavailable from the power input section.

Abstract
A replacement battery pack for an electronic device has a power storage section having a secondary battery. A power input section has at least one power connector for receiving electric power for charging the secondary battery while powering the electronic device. A power output/input section has an output terminal for receiving electric power from the power input section and for electrical connection to a connector of the electronic device to power the electronic device, and an input terminal for connection to an external power source for directly charging the secondary battery while the output terminal is disconnected from the connector of the electronic device. An input power switch circuit selectively inputs electric power to the power output/input section either from the power input section when the electric power is available therefrom or from the power storage section when the electric power is unavailable from the power input section.
