What is a Smart Battery?

A smart Battery uses electronics to communicate with it's host device in order to protect, monitor & control all aspects of it's operation. The sophisticated electronics maximize energy density and cycle life ensuring that all the cells within the pack perform at their optimum level. The electronics can also provide highly accurate and precise fuel gauging, and report critical information about the state of health of the battery.

As portable electronic devices become increasingly complex, more and more devices are relying on smart battery packs to provide accurate fuel gauging, monitoring and diagnostics. Lee&Jack Power is dedicated to the design and development of these battery systems to support the needs of today's portable electronic devices.
