I just used a windows 7 tool to check the status of my battery. I checked a report I still have from about 1.5 years ago and both the Last Full Charge and Design Capacity were over 4500. The test today showed about 3800. Why has the design capacity changed? Surely this is a set figure? I calculated a loss of 17% since the other test, but no idea what the total loss is because I dont know the true design capacity.
It's probably worth doing a test on a new battery and then going by that in future.
