I purchased a new battery from a 3rd-party dealer for my XPS 15 laptop. The battery is a genuine Dell and looks exactly like my old one. However, BatteryCare reports the following:
Current battery capacity: 100%
Designed Capacity: 57720 mWh
Total Capacity: 19281 mWh
Current Capacity: 19281 mWh
Charge/discharge rate: 0 W
Tension (Voltage): 12755mV
Wear Level: 66.60 %
... and the Dell battery meter program says that the battery is at "the end of its usable life"....
Is the battery just mis-reporting it's status, or did I buy a dud?
