The aluminum Apple Wireless Keyboard comes with three nonrechargeable AA alkaline batteries. You can also use lithium or rechargeable AA batteries.
Note: If you need to install or replace batteries in the older Apple Wireless Keyboard, see this article.
To install the batteries
- Use a coin to remove the battery compartment cover.
- Slide the batteries into the battery compartment as shown below.
- Replace the battery compartment cover.
If you have never paired your keyboard with your computer, you'll need to do that before you can use it. See this article for more information.
If you have previously paired your keyboard with your computer, you do not have to set up the keyboard again after replacing the batteries. The keyboard should automatically pair itself with the computer a few moments after you turn it on.
Important: Make sure to put the positive and negative ends of the batteries in the keyboard as shown in step 2. The keyboard will not turn on if the batteries are incorrectly installed.
When you change the batteries, replace all of them at the same time with the same kind of battery. With lithium and other battery types, do not open the batteries, expose them to flame, or in any other way violate the manufacturer's instructions. Dispose of batteries according to local laws and regulations.
