Apple Duo 270C manual Disposing of dead batteries, Replacing the backup batteries

Disposing of dead batteries

SImportant: Nickel-metal-hydride batteries contain metals that can be reclaimed and reused. Instead of throwing away dead batteries, please dispose of them as described here.

In the United States: Return dead batteries to your Apple- authorized service provider, who will make sure they are included in Apple’s battery recycling program.

Elsewhere: Many countries have government- or Apple- sponsored collection and/or recycling programs for dead batteries. Dispose of dead batteries in accordance with the mandatory or voluntary battery collection schemes in your country. Contact your Apple-authorized service provider for information about the recommended battery disposal procedures in your location. If there is no government- or Apple-sponsored return program, you can dispose of the batteries with your regular trash, taking care not to break them open or incinerate them. S

Replacing the backup batteries

In addition to its main battery, your computer has two small backup batteries that maintain the contents of RAM while you replace the main battery.

The backup batteries usually last for several years. You may need to have them replaced if you notice that some of your system settings changed after you removed or replaced the main battery. (You may notice, for example, that the clock time is different.) By replacing the backup batteries you can preserve the contents of RAM the next time you change the main battery.

Your computer’s backup batteries must be replaced by an Apple- authorized service provider.
