So i have been monitoring the battery in the STI since I have had it since 2011 LOL. Its an autocraft gold 850 CA , I had another one in a muscle car that I bought in 2007 that finally stopped holding a charge last summer, so that one lasted 12 years.
So being that I havent had to buy a battery in a decade LOL, I had been pricing a new autocraft battery at the local Advanced Auto, but just this month suddenly when I went to price one, they all came up as DIE HARDS? Looks like they arent selling Autocraft anymore?
I am a stickler for battery maintanence, I just keep them spotlessly clean and remove corrosion from the contacts whenever I see it starting....and occasionally trickle charge them If I see them go down after sitting for awhile. I think I have a bad cell in the battery from 2011 in the STI right now as it will sink to 11.8 if it sits for a day, but will charge right up to 12.6 (13.4-`13.8 while driving it), and stay above 12 after the car is shut down. So still holds a charge but its not quite 100% cell strength anymore,hence why I am going to replace it.
