Help Best place to buy batteries?

[AngryOwl]

Both our phones are quick to die on battery life, could anyone recommend a place to get good quality replacement batteries? We bought 2 from amazon from a third party ship and they were both garbage and couldn't hold a charge.

Thanks

I bought a Mugen-Power 1800mAh extended battery and it has been great. Picked up 20-25% more run time and it still fits under the stock battery door. High quality battery.

I bought it directly from Mugen.

extended batteries suck, unless you can keep the stock cover like the guy above you said.
You will lose so much signal. I went through two and even the htc extended battery was garbage!
I use juice defender, it gets me through the entire day love it. Although it can mess with my gps, so i just disable the app when using it.
