Battery for Epic 4G

[Cell Zeus]

I purchased a battery off Amazon 2 months ago for my Epic 4G.
I noticed the reviews and other people have posted good things using the battery with the epic 4G.

I was looking for a spare so I could switch the battery out when i was on the go. I guess it doesn't help that I am addicted to my phone.

The battery is still giving me good life and would recommend it.

Is that just another battery or is it one of the ones with the extended life? I purchased the extended life one for my wife from samsung epic accessories, and she likes it a lot. It was a lot more expensive than the one you posted, but she claims to notice the difference in it's life as opposed to the original the phone comes with.
