If you were holding off on buying one of Seidio's 3800mAh batteries for the Verizon Galaxy Nexus because they weren't compatible with NFC, here's something you'll be interested in. The company has begun offering the big battery with built in NFC circuitry. It's $75, but Seidio says:
When you can’t get to an outlet, our Innocell Super Extended Life Batteries will keep you moving forward. Our Extended Life Batteries utilize premium Japanese cells to ensure the highest levels of safety and performance. Super Extended Life Batteries can offer up to 100% more battery life than your stock battery.
With Verizon's power hungry LTE network, for many a spare battery is a must. Now that they have the NFC issues sorted, you can have that spare, in the XXL size, and still play with your hacked-on Google Wallet. Hit the link for details.
