LG Optimus G Pro battery compatible with G Pro 2?

[datum9]

Actually vice-versa. I wonder if an extended battery for G Pro 2 will work in Optimus G Pro?

(zerolemon 9500 mAh extended battery). The Optimus G Pro looks similar if not identical and is 9300 mAh. But wanted to confirm.

Some said that their G pro battery works fine on the G Pro2, but my G pro 2 keeps rebooting with the G pro battery, don't know why.
