Here's how to replace the batteries:
1. Locate the battery compartment: It's typically on the back of the Leapster 2.
2. Open the compartment: There will be a latch or a sliding door.
3. Remove the old batteries: Pay attention to the polarity (positive and negative ends) of the batteries.
4. Insert new AA batteries: Make sure the positive and negative ends are facing the correct way.
5. Close the battery compartment.
Now your Leapster 2 should be ready to use!
