Amazon.com: HTC Incredible Droid Eris Li-Ion Battery 1300mAh - Original (OEM) Battery: Cell Phones & Accessories: Reviews, Prices & more
It's a standard battery (only 1300mAh), but it's less than $10.
I just got my Incredible last week and so far I get better battery life than I did with my Droid. The Droid only lasted about 15 or so hours with light usage and the Incredible is lasting at least 5 hours more with moderate usage. Do you guys think 20 hours is a short battery life or is my Incredible something special?
As for better improvement, i followed the suggestion of "Mobile always on" and turned that off. We'll see how much it improves battery life, for now i'll stay unrooted as I'm going on a trip and won't have a PC in case something goes wrong.
Apparently the 10% drain is normal. The battery shelf life decreases over time the longer the battery is at 100%. They took this into account and made it so that after 5 min or so it depletes to 90% to save the life of the battery. There is an article i found about this but i cant seem to find it again.

You won't be disappointed. It's a huge improvement over the stock battery. I've read some of the reviews from Dinc owners who purchased this product and let me say that all were pleased! I can vouch for this as I've tested the battery for a couple of days now and the results have been amazing. The only problems I found was that the battery is supposedly a hair thicker than the stock but, the fitment is perfect! Also, it took about 8 hours to charge the first time for some reason; however, after the initial charge, it only took about 3 hours. I am also rooted and running SetCPU with Perflock disabled. This has allowed me to under clock my CPU to the minimum WHILE the screen is off which also helps to increase battery life. I am able to keep everything on including Wifi/BT/GPS/Sync/Autobrightness...Enable Mobile Data Always On is checked etc. I'll try to take pictures of my up/awake time but, let me tell you that I was getting almost 10hrs of awake time and 35hrs of up time with just a little bit under 15% battery life left! With little use, the battery could last for days!

I forgot to mention you can just get 1 battery for about $15 I believe. This can be purchased at htcexpress.com
Note: It's not the actual htc company but, I'm not complaining as the product is high quality!
By the way, I just snapped a picture of my screen to show you guys where it's at right now. I'll post up another one as an end result soon.

And BTW, I bought that same battery from HTC Express. Not only does it make the battery door fit awkwardly (exposing some of the red around the bottom edge) but my stock battery lasts longer with the same usage pattern. I have thoroughly tested this because I really want the "1800mAh" to be better than my stock battery.
