3 Batteries in A31p?

[XiP]

For the A31p, is it possible to use an Ultrabay 2000 battery in the Ultrabay 2000 bay and another one in the Ultrabay Plus bay for a total of 3 batteries?

Also, how long do ultrabay batteries last?

negative - the ultrabay 2000 battery will only fit in the ultrabay 2000. With both batteries in my a31p has a run time variable with speedstep. The lower the cpu rating - the longer the runtime. But on average running full power it's about 2 hours. About 2.5+ when running at half-speed.
