It stays at the 3.6 volt level, at least, for about 99.44 percent of its lifetime, then it slowly tends towards 3.2 volts. It is considered dead at 3.0 volts, although most models will continue to operate properly until somewhat below 3.0 volts. The curve is so steep at 3.0 volts that you might as well toss the battery. These batteries are so ubiquitous that Mac recyclers generally pull them, test them and sell them, usually for a buck a battery for such a "pull". --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
