Subject: Useing a laptop battery as a non-computer power source

This is probally going to be an odd question but here goes.

I know that most of the LiIon packs for computer laptops are in the 40WHr to 50WHr range with a few exceeding 60WHr. Found one battery for the Dell Inspiron that has a whopping 96WHr (14.8 volts at 6450 mAh) to it. This would make for a nice battery pack for other non-computer applications. Seems to me that they are more readily available and cheaper than other LiIon packs in it's class. Picked up a battery the other day just to play with it and found a 9 pin connector and no 14.8 volts on any of the pins. I can only guess there there is some control line that needs to be pulled low or something like that in order to turn on the internal circuitry within the battery pack. I could probally open up the pack and reverse engineer the thing but doesn't hurt to ask if someone else has already done so and what they learned.
