    Patent number: 6252379
    Abstract: A cell current limiting circuit includes a current-limiting device that electrically couples a cell to a battery terminal. A bypass current path is in parallel with the current limiting device and is selectively interruptible by a switch. A switch control circuit is capable of sensing if the battery terminal is electrically coupled to a selected host. The switch control circuit closes the switch if the battery terminal is electrically coupled to the selected host and opens the switch if the battery terminal is not electrically coupled to the host.
