I keep seeing these 2 names on the extended batteries. Can you explain to me the difference (if there is one) and the different powers and what it means in "battery life?" Also, I have the body glove on and I like it, but if I should get an extended battery, it won't fit. I do see other cases/covers out there, but how do you know which one fits? I did go to the new DroidForums accessory store (yea!) and tried to figure this one out myself. I am still confused - not a techy person, I guess.
