Patent ID: 8004244

Claim:
An apparatus comprising: a battery for powering a computer system; and a control module which controls said battery and monitors a plurality of battery conditions; said control module-further acting to: use a first fuse to prompt disabling battery power to the computer system responsive to a first voltage associated with a battery over-charge condition; and use a second fuse to redundantly prompt disabling battery power to the computer system responsive to a second voltage associated with the battery over-charge condition; wherein said control module monitors and responds to the first voltage and the second voltage independently; wherein, the second fuse is prompted to disable battery powering of the computer system as a back up to the first fuse; and wherein said control module further acts to: measure cell voltage when the battery is neither charging nor discharging power to a load; and responsive to a voltage decrease over a predetermined threshold over a predetermined time period when the battery is neither charging nor discharging power to a load, trigger a third fuse to disable the battery.
