Optima battery terminal question

I'm new here and I've been looking around at different threads that have been quite helpful with my prius. TLDR: skip to the italics.

So on Friday, I drove my prius 2 miles up the road to get a drink from the gas station. When I got back in, the car would not start. It was totally dead. I thought it might have been the key fob. I got a ride home, and hopped in the other car with the spare fob. Oddly, the car started making some noise, but wouldn't start. I thought I had either a dead fob or hit the key button by accident. Then all of a sudden the car started. But, being that I drove the other car, I couldn't drive it home ha.

Ok, so today I went down to O'Reilly's to pick up the Optima Yellow Top. The battery that was in there....whoever installed that should be hung out to dry...they installed some Napa battery IN A GROCERY BAG!!! It wasn't even vented properly and how this car didn't explode, I will never know. There was battery acid everywhere in the bottom, the posts were caked and the vent plug was just hanging around. I have only had this car since the end of May.

Of course, O'Reilly's couldn't install the battery there because they're not allowed to install "difficult" batteries. So, when I got home I discovered the terminals are too big for the Optima posts.

So, that brings me to my question.......the kit that is mentioned from elearnaid, is that to convert the original prius terminals to fit the Optima pencil posts? Can I get the post kit from somewhere else so that I can install the new battery ASAP?? Sorry that I do not know if these terminals are OEM or not (I haven't researched it yet as I figured asking would be faster than sifting through links for the right answer).

And, yes the OBD2 reader showed the code for "Lost Communication with Battery Energy Control Module A." I had the red triangle with the engine light. But, after I got the car back home on Saturday and started the car again, it went away.

While at O'Reilly's the car wouldn't start again. After a few minutes it's starts. I'm assuming it was because we messed with the battery to test it. Since we took the battery out we cleaned all the corrosion off the posts and re-inserted it until I can get the right terminals. It started at least.

 

Yes, the battery that is currently in the car is fat posts. So, I will either need to get the fat post battery exchanged out or find shims. But, honestly, if you saw the positive terminal, you would probably cringe. It looks like crap, rusty and misshapen. I would probably be better off getting new terminals altogether. It's just a matter of making sure I get the right size for this project as I don't know what the originals were. Thanks for the reply!

 

No, the Napa battery was SAE.

I ended up using shims on new terminals, since the terminals that were on it (the SAE converted ones) were in really bad shape and went ahead and replaced the lug on the negative cable since it was literally hanging by a thread....or a few anyway.

I haven't had any issues with the car starting today either.

@PriusCamper I guess the Optima's are hit or miss around here, as most of the comments I've read suggested it, which is why I went with it. Just wish I had paid more attention to the terminals before I went down this road, ha.
