-Battery took 4 hours to charge up to 4.218 volts
-Estimated full from empty AC charge is 4.5 hours
-No heat generation to speak of during charging or use so far.
2012-01-02:
-Battery has been charged and fully discharged 3 times now. Reset all stats and running an Antutu Battery Test on it that I will also run on the stock and CS 2200 mAh to have some comparisons that mean something.
Testing setup is as follows:
-Same phone with CM7.2 overclocked to 806 mhz to speed up the testing process for all three batteries
-Batteries all conditioned and then charged for 8 hours prior to testing
-No changing of configured apps, services, etc on phone during testing
-batterystats.bin and Battery Monitor Pro history is wiped between batteries
-Wifi and data turned off so the phone does essentially nothing
-Antutu stops phone from locking, dimming, downclocking etc. so it's basically running all out for the entire duration
-No one seems to know what the scores are or how they relate to anyone else but I figure they will relate to each other.
-Once test is complete run Antutu again to run the battery down to 1% for shutdown and get final burn time results from Battery Monitor Pro

Final Results For ECell Gold, HTC Stock, and Cameron Sino:
-3 Hours and 44 Minutes For HTC Stock Battery
-4 Hours and 19 Minutes For ECell Gold Battery
-7 Hours and 35 Minutes For Cameron Sino Battery
-The ECell Gold, at 13.34% more capacity than the HTC Stock battery, comes in at far less than it's advertised 2430 mAh.
-The Cameron Sino, at 50.52% more capacity than the HTC Stock battery, comes in at more than it's advertised capacity of 2200 mAh
The Conclusion:
You can't make a silk purse out of a sow's ear and you can't cheat physics.
Applying the same battery technology you can really only expect marginal performance gains in the same form factor as is shown with the underachievement of the ECell Gold compared to it's advertised capacity.
There were no surprises here.
Double the form factor brought double the capacity. If you're cool with a "Fat Phone", the Cameron Sino Technology 2200 mAh battery lives up to it's expectations and puts some reality back into things. You get a very high capacity battery at a very reasonable $22.00 US
In it's own right the ECell Gold 2430 mAh is a great idea for a cheap and higher capacity replacement battery and that's really the positive in that storyline.
The price is right for a slim replacement battery but they need to stop the gimmickry and advertise it for what it is.
False hope is NOT better than no hope.
