Posted February 14, 201312 yr I'm ready to tackle the electrical system of my 2011 Malibu. Under the hood battery is a weird group 75 battery. I'm either going to try and modify for a slightly larger battery or just spend the ~$200 die hard platinum that will fit as is. Thing is I'm trying to do this on a slight budget and its gonna be cheaper to use different brand batteries. Just going to put 1 in the trunk. I plan to only use sealed AGM style batts just possibly different brands and sizes.. Any trouble I can avoid here?
February 14, 201312 yr the biggest deal usually is having wet cell and AGMs mixed, while it works, since they charge and discharge differently, they can shorten each others lives. AGMs with AGMs, you dont really have to worry about.
