Valence's N-Charge 5 & 10 Hr Batteries Now Fit iBook and PowerBook Models

The web site lists the iBook, PowerBook 3400, G3 and G4. There are two models, a 5-hr model (<2 lbs) for $149 with rebate and a 10-hr model (<3 lbs) for $299. They should also fit other models like the PowerBook 2400c for which batteries are now very hard to come by.
