[QUOTE="pigoo3, post: 1178003, member: 56379"] It's all in the math. Like "6string" mentioned...all batteries are not the same. When new...some batteries have a slightly higher amount of mAh's & some have slightly less. In "6string's" example...his battery has a design capacity specification of 6900mAh...but his battery has a current actual capacity of 7020mAh (120mAh higher than the design spec.). It's possible that a battery has a 100% capacity specification of 6900mAh...but batteries from the factory may actually range from 6750 to 7050...so +/- 150mAh. Now you take the program "Coconut Battery". It has some sort of table in it's program that says "6string's" battery at 100% charge is supposed to have 6900mAh...but in reality (when the battery is fully charged) it has 7020mAh. So if you do the math...that works out to be 101% of the original design specification. HTH, - Nick p.s. Technically speaking...a battery with a design capacity of 6900mAh...but an actual 100% charged capacity of 7020...is at 101.739% (almost 102% if you round it up)!:) [/QUOTE]
