Sometimes Newer is better than new

Stalwarts in the Macintosh community, Other World Computing (OWC) and NewerTech started shipping their new high-capacity replacement batteries today for the 15-inch Powerbook G4 (Aluminum) under the NuPower label.  Priced at $129, these batteries boast up to 6% more capacity than the priginal Apple battery.

I personally replaced my 1st generation 5GB iPod battery with an OWC/NewerTech replacement a few months ago and I continue to get 20+ hours per charge out of it. Simply amazing. I have no doubt their Powerbook batteries are just as impressive.
