Above instructions are great except that it is in fact much easier than that. You don't need to take off the cover that's attached to the glass - that means you don't need to do anything with the wiper.

Tools: 13mm hex, small adjustable spanner

Battery: Wal-mart EverStart 48N ($77 before tax)

Steps:

1) Pop the hood and take off the battery cover (the entire set as shown in the above instructions)

2) Use the spanner to take off the battery connectors (negative first then positive)

3) Unplug the vent pipe

4) Use 13mm hex (probably with extension) to take off the bracket that holds the battery on the left (negative side).

5) Take off the center clip of the cover that's attached to the windshield so that the cover can come off a bit to make way to the battery

6) Now take the battery out by holding the battery grip

7) Put back in the new battery

8) Put the hose and the connectors (positive first then negative)

9) Put back the center clip to the cover, and place the battery cover

10) Now set the clock :)
