I downloaded a battery image (containing 16 images) and put it in Private>var>mobile>library>customize2>battery. Had to delete the stock battery and rename my custom battery to match the stock battery (I.E. renaming each battery as battery1---battery16). Well, after putting it on my ipod and I go into customize and select the battery image, I see my custom battery but it says "missing battery17" meaning it needs a 17th image which is not included. What is the proper way to install MY battery?
