Method for monitoring the condition of a battery in a high temperature high current environment

摘要

A method for battery condition testing. In one embodiment, the method is comprised of interrupting AC power service to a data storage system. The interruption causes an exhaustible power source to provide operating power to the data storage system. The exhaustible power source is coupled to said data storage system. The exhaustible power source is adapted to provide operating power to the data storage system when the AC power service to the data storage system is interrupted. The method is further comprised of discharging the exhaustible power source by operating the data storage system with the exhaustible power source for a specified period of time less than full discharge but sufficient to fully flush the cache. The exhaustible power source passes the condition testing provided the exhaustible power source provides operating power to the data storage system for the specified period of time. The method is further comprised of recharging the exhaustible power source subsequent to the exhaustible power source passing the condition testing.
