Replacement batteries for Sony a7ii

[dietter700]

What have you guys found to be decent replacement batteries for the Sony a7?
We all know how they suck the battery, I need to get a few more in my arsenal.

We have sold hundreds of the Promaster FW-50 batteries. Great battery, no issues and lifetime warranty

How much?

We have it available 2 ways. Battery with a wall charger, since most Sony cameras charge in the camera, this is awesome, would be $39.99, or the battery only would be $29.99
Thanks
