This is just a small writeup. I was going to do a dual battery install but my budget is pretty tight this year.
I replaced that no name POS OEM battery that was in there. Its pretty god damn big compared to replacement batteries though
I went with the biggest battery Autozone had a 49-DL. Its
850CCA and
1000CA and 155minnute reserve capacity at what wattage/amp draw im not sure (chime in if you know) I made my own tray although it was unnecessary. I used a street sign from work for material. Its dense aluminium. I also had to shorten the OEM bolt down rods. I used a cutoff wheel and some heat to rebend the ends to hook in the OEM locations.
I plan to add a air intake later to make room on the other side for a second battery. Here are some pics.
