What is the best extended battery for Samsung Galaxy S3?

[Kelli]

First, I would not ever buy batteries on sites like ebay or amazon. They are great for buying a lot of stuff but not electronics. Sure they are cheap but you get what you pay for and they are often used, refurbished or knockoffs.

Second, Samsung will rip you off with the price of their extended battery and it probably wouldn't be as powerful as an aftermarket (generic) brand. I got the Galaxy S3 in blue and just got and extended battery here:

This battery is double the power of the original battery, had a year warranty/return policy and free shipping. It is working great!

Good luck!
