Other World Computing (OWC) and Newer Technology today expanded their line of replacement Titanium PowerBook batteries by introducing the highest capacity battery available for the 15-inch PowerBooks. The newest addition to the NewerTech NuPower Lithium-Ion battery family is rated at 74 Watt Hours (W-H), providing up to 48 percent more run time capacity than Apple factory-shipped batteries, according to the companies. Apple shipped 50W-H battries with original 400MHz/500MHz PowerBook G4, but continued to upgrade the battery capacity as the G4 PowerBook line evolved, offering 61W-H batteries in the 867GHz/1GHz models of the Titanium PowerBook G4. The new 74W-H battery is available for $150 and includes a one-year NewerTech warranty.
