I was in advance auto picking up a boat load of parts that I bought yesterday. They have a program that will buy back your old car batteries for $5 gift card. They said that they must not be busted, cracked, leaking, etc and they said that it must be an auto battery (not lawnmower or motorcycle). I had one in my trunk that I planned to use as a core when I bought my optima battery last week but there is no core for optima batteries. I was able to cash in my dead battery for $5.
While I was in the store someone else brought in 8 batteries for gift cards. This is an easy way to get rid of those batteries in your garage or on your farm.
I know that you can scrap these at the recycling facility for more but who has time to do that when you are already at the parts store.
