The Optima in my Infiniti is 10 years old and still going strong but I've read so many bad things about them recently, I would be hesitant to buy another one.
I have a red top in my 4 motion b6 Passat. I have not had any electrical issues. As long as the optima matches or exceeds the oem battery cca you’ll be fine.
We have one in our 2007 and it has been going strong for almost 7 years.
My truck has a 4 or 5 year old Bosch in it, still works great.
Factory exhaust manifold cooling and Bosch battery.
I purchased 2 as a drop in replacement for an old 1400VA APC UPS.
I couldn't find the datasheet on the bosch website but I found out via a few online posts that these batteries are actually manufactured by Exide.
Optima battery recommended. Expensive but large capacity for emergencies.
Used redtops for years. Had a couple go bad, but 3 year free replacement warranty solved that.
My optima failed after 1.5 years
Johnson Controls ruined Optima.
