Will not turn over, just clicks 2009 Jeep Grand Cherokee

Sometimes will not turn over, just clicks. Battery is good and relays appear to be working. Has only done this 4 times in the last year and a half but getting more frequent.

First thought, Replace Starter.

In general if you hear one hard click, the starter needs to be replaced. If you hear several clicks repeating(click, click, click, click, click) the Battery is Dead/Weak and may need replaced. If the battery is close to 4 years old or older, replace the battery anyway.
