Replacing the Internal Backup Battery

Your Mac Pro uses a BR 2032 lithium coin cell battery that preserves settings, such as the date and time, when your Mac Pro is off. If you notice intermittent problems when your Mac Pro starts up, or changes in the date and time settings, replace the battery.

Important:  Dispose of the old battery according to your local environmental laws.

To replace the battery:

1Open your Mac Pro and remove the side panel, following the instructions in “Opening Your Mac Pro” on page 39.

2Remove any PCI Express cards that block access to the battery. See “Adding PCI Express Cards” on page 74 for instructions.

3Remove the old battery from the holder.

WARNING:  Installing the battery incorrectly may cause an explosion. Use only the same type of battery or an equivalent recommended by the manufacturer of the original.
