If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes). These batteries only work in one direction, transforming chemical energy to electrical energy. But in other types of batteries, the reaction can be reversed.
A smart battery is any battery that contains its own battery management system. It is often used in smart devices including laptops and mobile devices. A smart battery has an internal electronic circuit and sensors that can detect voltage and current levels as well as other parameters such as state of health and then communicate them to the device and, as an extension, to the user.
