    Hi, is the Lenovo 6-cell 2.8AH battery the same thing as 6-Cell 57 Whr?

    Power [Whr] = Current [AH] x Voltage [Volts]

    Depends on the voltage of the battery. It would need to be 20.4 V to get the desired capacity.

    57 Whr = 2.8 AH x Voltage
    Voltage = 20.4 V

    Hmm, because on my order page it just says 2.8AH, but on the customization page there's only 57 Whr. I don't remember what it was originally and afraid they upped the standard battery after I ordered
