The charge capacity of a battery decreases after numerous charge cycles. asus batteries are designed to hold at least 80% of their original charge, even after hundreds of charge cycles. 4. do not store the battery pack in a damp or cold environment! moisture or a cold environment might speed up the discharge rate.. The capacity of my battery is now less than half what it was a little over a week ago, and when plugged in, occasionally, it will say the battery is charging, but never gets past 85%, or it says it's plugged in and not charging, but in both instances, as well as when the laptop is unplugged, the battery light blinks..
