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.
