Voltage and capacity define the fit

The 11.4V 46.5Wh rating must match the original battery label exactly for the laptop to charge and report capacity correctly. A different voltage or watt-hour value will cause charging errors or incorrect runtime estimates. Verify the numbers on your old battery before ordering.
