Battery replacement - Battery from Sony Xperia Z2 into my Xperia Z

Hello xda Guys.

I am new and I have a question. Since I have updated my Xperia Z I have problems with my battery time. Before I have done update my battery was very slow too, but now it is horrible. I wanted to replace it four months ago, but I hadn't time. Now my question: Can I place the battery from the Z2 into my Xperia Z, or not?


Thanks Guys for your help
