Just thought I would share this deal I found on eBay for replacement batteries!

It comes with 2 1500mah (200 more than OEM battery) and a Battery Cradle style Charger so you can charge one out of the phone, and just swap them out when you need to

I am going to order a set and will let everyone know how the performance stacks up.. even if it only gets an extra hour or 2 per charge, $17 bucks for 2 of them, AND a charger, can't beat that deal

Update:
I just ordered them, but realized they are coming from Hong Kong, so it may be a week and a half to 2 weeks before I receive them, But I will be sure to let everyone know how they work out when i get them!

I have been looking at these and some other replacement battery options but I am a little concerned about removing the back cover on a regular basis, maybe even a couple of times a day on a really heavy day. Any thoughts on this? My main concern would be that the snap type back cover will become loose pretty easily from repetitive removal.


 

Damn those are annoying!

Plus, you can always fix it with duct tape.

Haha! 
I hope it works for the best for you.
(I wasn't really serious about the duct tape) 

Did you get your batteries Eddie? Mine where shipped and I'm waiting, just wondering if you had any feedback.

The batteries and charger are nice, the charger itself is well worth the $20. The batteries are performing well and there is probably at least a 4-8 hour improvement over stock. Despite the 20 day ship time I am very happy and would recommend this if you want a little extra battery life for a little $

Yea if you're leaving in 30 days I would order now  I think I ordered during the Chinese new year so maybe that slowed things down 

Sorry for the delayed response about these batteries everybody.. But I did receive them within about 2 weeks of ordering them (they came from china) and i LOVE them..

Here are some of my stats of the batteries

Charge 1 - 1500mah
at 15% life left:
Up Time - 28:41:42
Awake time - 3:35:10

Charge 2 - 1500mah
at 15% life left:
Up Time - 30:30:07
Awake time - 3:07:06 (10%)

Charge 3 - 1500mah
at 15% life left:
Up Tme - 43:42:09
Awake Time - 2:46:05 (6%)

AS YOU CAN SEE HERE^^^^
the new battery lasted me about 48 hours... with normal person usage lol..

It seems to me that after multiple charge cycles (draining completely, and charging completely) these batteries' lifespan grows! I am loving them!

I took a control reading of my OEM HTC battery as well to compare..

1300mah
at 15% life left:
Up Time 30:35:09
Awake Time 3:22:05(12%)


All in All, you don't get a TON of extra life, but the few hours you will get with the new battery really do help! (for me at least)
The thing I've liked most about this purchase is the Dock style Charger for the batteries.. it also has a USB port to plug in your cable and charge your phone normally if you wish..
Having an extra battery in my pocket has helped me out of a bind once or twice already!
I got lost on the road late at night last week, and was using google maps to help me get home. but my battery died.. luckily i had my backup battery because I did not have my car charger with me at that time lol...

I hope this information is helpful
