How do you fix the Clock reset problem?

I need to reset the clock after each power-down.

I am sure I need a pram battery, just not sure which one:

The 3v lith coin cell, or the:

The G4 Titanium Mercury PRAM Battery @ $39.95

Product code: IF121-017-1

Apple Part #: 922-436

Do I need to open up the case to see which one?

Thank you.
