Sold the wrong battery

[royally effd]

I bought a battery on Friday. I went in-person because I wanted to make sure that I get the right one. I know you can not return batteries, hence my wanting to be sure.

 

I was sold the wrong battery. It's too big for the tray. I currently have a small battery and I knew that I could remove the sleeves used to hold the small battery. I didn't question the size because I thought it would fit on the big tray underneath the sleeves.

 

I have him as much information as I had and even showed him the pictures of the battery. Other than suing them in small claims court, what would be a good course of action?

Where did you buy the battery? If you got the wrong size, most retailers will let you exchange if not installed. They should have looked up the correct battery...Autozone, Advance, O'Reilly, Napa, etc.
