I personally have done this, and it's such a good way to get more practicality out of the car. Fortunately, it is made stupid easy to do this conversion on park avenues, which makes me wonder why it wasnt that way from factory. The side post bolts into the lug ontop of the battery. 13mm bolt takes it off. Then buy some marine terminals and voila you have a beautiful connection to the battery that is easier to maintain, stronger, easier to jump off, and simpler.

And don't mind my battery, I paid 300 for that beast of an AGM and it was well worth it, started my car in the recent polar vortex with ease. Having the ability to deep cycle and longer life will make it a well worth investment.

In my case, I purchased some top post brass terminals off amazon for about 13 bucks that are solid and will help prevent corrosion between themselves and the brass posts of my battery. I am going to change the wing nuts, however, for some brass nuts. But that is down the road.

A very interesting modification and I am glad that it is working well for you during such cold weather! Thanks for sharing the picture.

I have done the same thing, highly recommended!

After being through 3 ACDelco's in as many years (the only side-post battery I can get here) I finally had enough. I did not invest in an AGM though, I spent 120 for a Bosch standard. Also, I replaced the side post bolts by cutting them and put new clamps on the cables.
Now, 18 months and a couple of deep-discharges later, the battery still works like new.
