Will battery from G Pro 2 work in Optimus G Pro?

[datum9]

especially the extended kind, the zerolemon 9500 mAh battery.

are the batteries compatible between these two devices? I realize probably not, but wanted to check.

They might not be interchangeable, since they have different part numbers. The G Pro's battery is BL-48TH (http://www.amazon.com/LG-BL-48TH-St...ag=hawk-future-20&ascsubtag=UUacUvbUpU3989140) while the G Pro 2's battery is BL-47TH (Original for LG Optimus G Pro 2 LG F350K F350S F350L D837 Battery BL 47th | eBay). But I couldn't find any information from anyone who has tried to swap them.
