摘要： The present invention applies load to a portable telephone by charging and discharging a secondary battery conforming to the actual way of use of the portable telephone, so that the performance of the secondary battery in a portable telephone connected for charging can be accurately tested. A battery testing device of the present invention has: a charge control circuit for controlling input power which is input to a lithium ion battery via an AC adapter; and a radio circuit for controlling output power which is output from the lithium ion battery and discharging the lithium ion battery, wherein when the lithium ion battery reaches a fully charged state, the radio circuit starts discharging while the charge control circuit stops charge of the lithium ion battery using the AC adapter, and when the lithium ion battery reaches a predetermined charged state, the charge control circuit starts charge of the lithium ion battery using the AC adapter while the radio circuit stops discharge of the lithium ion battery.
