Laptop batteries are rated in W⋅hW⋅h, the product of the power (in WW) that the battery can provide and the time (in hh) that it can provide this power. For instance, a 50 W⋅hW⋅h battery can provide 50 WW for 1.0 hh, 25 WW for 2.0 hh, and so on. A 10.8 VV laptop battery is rated at 74 W⋅hW⋅h.

    6.85C

    Explanation:

    the charge and the current are related by

    Q = I*t

    where Q = charge in columbs

    v = 10.8

    P = IV

    I = P/V = 74/10.8

    I = 6.85 A

    the battery will supply a charge of (6.85*1) C

    6.85C
