Battery OPTIMA or Exide

I'm a fan of Optima, I run them in all of my vehicles. I live in sub zero winter climate. Once I left my car sitting for an entire week during -40F windchill. Everyone else needed jump starts, my car turned right over and came to life. I've accidentally left interior lights on overnight with no issues starting in the morning. On top of the performance is the longevity, the battery lasted a decade with no issues.

My Optima same model as that, is on its 11th year . Yes, non-corrosive. I switched to AGM because I was tired of batteries coming apart at the top seam and leaking acid into the engine bay. I have never had corrosion on the Optima terminals, either. Recently made Optimas have lost their good reputation however, so if you buy one, make sure you can return it if it dies prematurely. I have switched to another brand AGM on the basis of those bad reports.

My TT has an OPTIMA YELLOW TOP. Battery put in service date 12/2006 9 years on a battery in this heat...un freakin heard of! Very good value for down here.

Been running an optima in both my cars for years. Best decision ever.

Next battery I am going to put in my Passat is going to be something made by Exide . I mentioned before that I changed my OE battery in the winter 2007-2008, was concerned with low temperatures of this winter, but battery seems to do very well, started at 9*F and still work without a problem.

Purchased a Red Top 35 today and it fits! I did have to take the bottom bracket and flip it so that the side of the battery facing the headlight [+ -] stayed secure.

I ended up buying a red top optima gel battery....expeeeensiiiive

But the battery's been fine. I got a Redtop after the factory battery died, then that Redtop eventually did wear out. So I got an Interstate, and it didn't stay the whole winter before getting shuffled into the Cabby or something that was summer duty/easy to start. I got another Redtop for the bug then and it's been fine.

Optima batteries have slowly gone to shit since they were bought by Johnson Controls.

Their batteries have never been great, and they've always failed prematurely for myself and several others.
