No, it is not. It's dimension are 19mm dia. x 5mm height. A little bit more than the batteries that are use inside the HP 30B.

May be you're right, but I don't want to use AAAA-batteries. Taking apart 9V batteries and soldering them in anytime you have to replace the batteries seems uncomfortable to me.
