Abstract
A method, an apparatus, and a computer program product embodiments are disclosed for detection of the availability of a battery (160) by a host terminal (100) during a data exchange session with the battery (160). In accordance with the embodiments of the invention, sampling, data communication with the battery pack (150), and detection of battery (160) removal, may occur substantially simultaneously. The battery (160) removal may be detected during data transmission from the terminal (100) to the battery pack (150). Moreover, a response may be received by the terminal (100) from the battery circuits (155) in response to data communicated to the battery (160) on the battery communication line (140), during sampling in a timed manner.
