The link you provided doesn't work from my location.
Does the laptop work without the battery on just AC?
There aren't available schematics, HP/CPQ do not want you taking apart the batteries. The only suggestion is to use a multimeter and check the circuit board for shorts and opens that shouldn't be there. You will have to experiment or compare it to another battery.
