The battery in my dad's truck went dead and he wants me to take it to autozone to get it charged. The only problem is I don't know how to get it out, and he can't do it because he is out-of-state. I was wondering if you guys can take a look at some pictures that I took of the battery and it's terminals.

Link contains all the photos of the battery (Silverado Battery - Imgur)

I can remove the positive terminal fine, but it's the negative terminal that will not give. Any ideas?

 

Try using vise grips or channel lock pliers.
