MyBattery is a utility program designed specifically for portable Macintosh computers. It provides you with information about your PowerBook batteries and system. Its features include:

• User-customizable display. You decide what information you want to see.
• Displays information about internal batteries, including charging status, charge level and battery voltage.
• Estimate of useful battery time remaining. It uses a historical estimation that "learns" from your PowerBook usage patterns.
• Displays power-related system information like hard drive status, AppleTalk status, and modem status.
• History window which displays recent battery charge history, power consumption rate, and even temperatures on some PowerBook models!
• Support for multiple batteries, accommodating different capacity batteries.
• Menu bar displays, for easy viewing of battery status and other system information.

MyBattery's most popular feature is its ability to estimate how much battery time you have left. Using a historical estimation technique, MyBattery monitors your PowerBook usage, and updates its estimates accordingly.

MyBattery will run on any Portable Macintosh. Some more advanced features are only available on models that support them (for example, battery serial number support is only supported on Duos and and later systems).

NOTE: The temperature measurements do not work on the "Wall Street" and "Bronze" keyboard PowerBook G3's. The temperature measurements work on all previous PowerBooks, as well as the iBook and FireWire PowerBook. Installing Mac OS 9.1 may improve the compatibility of the temperature readings on older models.

NOTE: The temperature readings do not work on the PowerBook G4/400. They work fine on the PowerBook G4/500, and on desktop G4/400 systems.
