Re: whats the highest extended battery in atrix with otterbox def
I reviewed several such websites asking similar questions and trying to fit the largest battery I could in the Atrix. The Mugen 4800mAh XL Extended battery is awesome, but the door (cover) it comes with is pretty standard and makes the phone look like a black brick. After a little reseach, I decided to modify my Otterbox Defender to accommodate the giant battery. It was not easy, but I'm happy to share my steps. I'll post a few photos when I find the correct links.
