ABSTRACT:
When a rechargeable battery of a life safety device reaches its end of life, the life safety device provides an audible signal indicating that replacement is required. When the device is disconnected from line power, the rechargeable battery still contains a significant amount of energy. The device automatically begins controlled discharge the battery until the stored energy has been reduced to a safe level for disposal of the life safety device and its battery.
