I have this one

Odyssey PC680 Battery

Saved right at 30lbs from the Optima that was in previously. I’m not driving my car when it’s 20F outside, and I leave it on a tender. Really like the weight savings too.

13.5 lbs? That shit is heavy for an aftermarket battery! Mine is 6 lbs.

Lightest batteries I’ve heard of is a company called “anti-gravity batteries”. Big money but it’s 8.5 lbs, built in start charge, doesn’t fully die. Just yikes they are pricey.

I bought an AntiGravity battery for my F150. I went with the second lightest battery since I will be driving on the street and a little extra capacity is nice to have. Still saved 33lb over stock. The AG's are very pricey but the nice thing is they make standard case sizes that will bolt right into your stock tray. The "restart" technology is pretty sweet too, it cuts power to the vehicle before the battery is completely drained so you never come back to a dead battery if you forget the lights on, etc.

Now what model Anti-Gravity is that one?

It's an H6/Group 48 30 Ah. For a Mustang they recommend the H5/Group 47, then you can select 24, 30, or 40 Ah depending on your needs.

I bought the AG battery for my F150, not my Cobra. The stock F150 battery is really heavy.

I ran a PC680 for years mounted to my intercooler tank. I liked the light weight of it. When I moved my batter to the trunk I pulled it and went to a normal battery.

Wings65288 · Mar 10, 2021

How come u didn't keep the PC680 back there out of curiosity?
