It wasn't really 'performance', per se. It just seemed to run more efficiently. Everything felt smoother. But yeah, likely in my head. It's why I posted...just to see if anyone else had experienced this. I can already envision half of rennlist replacing their batteries this weekend. LOL.

The other day at a PCA tech for a DE event someone said "nice Battery". When I got home I went to see what kind of battery was in the GT3 I purchased. I expected an Optima or the like. It is a battery from Wal-Mart !! Is this of concern or OK ? When changing a battery if you use a 12 volt connection to the lighter will it retain memory in ECU?
or if you prefer,
no and yes.

So heres my experience ..
Guys, this could be the craziest observation. I installed a new battery over the weekend (Interstate MTP-H7...and boy, they aren't the lightest or the easiest to swing into battery compartment of the car but it's a PERFECT fit). Anyway, my old battery was getting up there in years and I thought it wise to proactively replace it...you know, instead of getting stranded on the road somewhere without being able to start the car. I took the car for a drive last night after letting it sit on the trickle charger to top it off and I was amazed. The car just 'seemed' to accelerate more crisply. I'm sure it's all in my mind, but does anyone know if putting a fresh battery in the car can have a positive feedback on driveability? I always thought the batteries were predominantly for starting since the alternator kicks in once the engine is running.
yes yes yes . So much so that I turned to the internet to research this. My batter registered at 39 out of the 760 that is recommended for my KIA Optima. The car accelerates so much faster and smoother noticeable difference.
