QuickerTek has announced an extended life battery (US349.95) for all
models of the Apple MacBook Air. The company says users gain eight to
12 hours of additional battery power beyond the power of the built-in
battery. This is the only product that charges the internal battery
of the MacBook Air while in use.

New technology allows 25 percent more power from a smaller physical
size battery, according to the folks at QuickerTek. This produces not
only a smaller battery, but also longer battery power.

Customers can either send in their MacBook Air MagSafe power adapter
for an upgrade ($25), or buy an already-upgraded MagSafe adapter for
use with the new MacBook Air External Battery Charger ($100). For
