2005 Prius battery terminals

About 6 years ago I replaced my oem battery with an optima. The optima came with larger terminal clamps than the Prius comes with. I discarded the original clamps without thinking much of it. Today, my battery finally died and I am looking to replace it with a cheap stock battery. Problem is, the stock (non-optima) batteries all have the skinnier posts that will not allow my clamps to screw down without significant play.

My two options are to buy another optima or find someplace that sells the clamps for a Prius battery. Any suggestions? Ordering an optima will put me out several days with no car.

Ive attached a photo showing my old optima with thicker posts and larger clamps compared to an off the shelf Prius battery.

 

I went to a dealer today, they said they ddnt have the parts or knew of where they would be. I'm going to try another tomorrow.

 

I tried several different auto parts stores, the best I could do is to get a D51 size battery with the larger terminals on the opposite side (short side) of the battery. The fit is a little tighter with the large battery pack vent sort of in the way. Also, the 12v battery vent hose will not reach due to the vent being on the other side, so I will nees to extend it. Such a headache.

 

Using an optima is my solution. I still find it insane that auto part store don't sell the terminal clamps for the skinny terminals. They sell the batteries with them but not the clamps for that size.
