What is a SMART battery?

A SMART battery is a battery pack that comes with both an integrated gas gauge computing circuit and a two-wire interface to allow the battery to communicate with a host device for the purposes of reading fields designed to provide information on the battery’s state-of-charge, state-of-health, reason of any protection, preferred method of charge, and many other items.

Each of these items is based on the Smart Battery System specification available at http://sbs-forum.org/specs/. Any battery which meets the standard of the SBS specification is deemed a SMART battery. The two-wire interface all SMART batteries are required to use is known as the System Management Bus and is available at http://smbus.org/specs/.

SMART batteries can be charged with compatible SMART chargers for added benefit and safety.
