Battery life detail
Battery life detail	Removable nickel-metal hydride battery; Apple claims two to four hours depending on configuration and battery conservation. The exact cs/133 service configuration lists 6.7 lb with floppy module and slightly more with CD-ROM. Support gives 2 × 11.5 × 9 inches; the generic service physical table instead converts the height to 54 mm, so conflicting metric thickness is not used	Removable 30 Wh nickel-metal hydride battery; Apple Facts claims two to four hours depending on usage and configuration. It gives PowerBook 1400cs weight as 3.0 kg with floppy module or 3.15 kg with CD-ROM; exact cs/166 support instead lists 6.6 lb with accessory-dependent weight. Support's six-inch height conflicts with Apple Facts' two inches; metric thickness and depth remain omitted because maker conversions also disagree
