This is definitely conflicting information from the battery. The last full capacity is 3.3 AH but it has 4.4 AH remaining? But remaining capacity can't exceed the last full capacity and therefore that can't be correct. Usually remaining capacity is your current charge level which goes down as you use it and up as you charge it. The high-water-mark of the maximum charge sets the last full capacity value. A little side discussion: A lot of vendors use remaining capacity divided by last full capacity to calculate the percentage of battery for display. So even if the battery was worn out at 1 AH if it charged to that amount then it would say charged 100%. That keeps their support calls minimized. Otherwise if they calculated it using remaining capacity divided by design capacity they would start out showing values such as 115% (which doesn't make sense either) and would over the next two years of use never charge above 75% and their customers would be unhappy. As a technical type I like to know both values but for the typical consumer neither one is suitable for them. Bob
