Express Charge benefits
● For a battery advertised as having the ExpressCharge feature, the battery typically will have greater than 80% charge after
about an hour of charging with the system off, and fully charged in about 2 hours with the system off.
● Enabling Expresscharge requires that both the Latitude notebook and the battery that is used on the system be
ExpressCharge capable. If any of the above requirements is missing, ExpressCharge will not be enabled.
