"Actually, I stand by my original post. The D2 battery, which is the battery the OP is referring to, is a 1300 mAh battery. The D2 extended battery is 1860 mAh .
Therefore, you divide 1300 by 1860, which comes to .70 or 70%. The remainder of the 100% is what the extended battery has to offer, 30% more."
Sorry, your math is all wrong. Think about it this way:
According to your numbers, the extended battery has 560 MORE mAh than the original (it offers 560 more mAh than the original). In order to determine a percent increase FROM THE ORIGINAL, you have to divide that increase BY THE ORIGINAL. 560/1300=0.4307 x 100= 43.07% MORE mAh than the original.
Just curious as to where you are getting your numbers from.
Both the og droid and the droid 2/global use the bp6x battery, which has a capacity of 1390 min, 1420 typical.
The bp7x has a capacity of 1820 min/1860 typical. I must be unlucky because both my stock and extended battery are rated for the minimum :/ but i digress! Simple math tells us that;
A)1390-1820=430
B)1420-1860=440
C)1390-1860=470
D)1420-1820=400
A)430/1390= 31% increased capacity
B)440/1420= 31% increase
C)470/1390= 33.8% increase
D)400/1420= 28% increase

I'm glad I'm not the only one scratching my head, thank you.
