Battery OPTIMA or OEM Audi

Optima battery. They handle the cold much better.

A lot of people say the Optima is not a good battery anymore, but I continue to have good luck with them.

I use an Optima Yellow Top battery and it made a big difference. The Yellow Top is honestly just good for the car in general.

I’ve got Optima batteries in some of the more “Special” cars.

Yellow top is/was a hybrid cranking/deep cycle battery, once popular for putting big stereo systems in cars because it could handle the discharge cycles of running the system without them engine running.

I had a Red Top Optima battery, but it’s so dead that even my NOCO AGM charger won’t recognize or charge it.

The optimas (red top) I got in 2019 are still going. They are not the best though just better than liquid.

Those Optima Red, Yellow and Blue tops used to be the cat's ass 20 years ago, but quality has fallen off big time in recent years

Optima batteries have, in my experience, gone downhill over the last few years. For their price, I don’t think they’re worth considering.

I purchased one because of my car stereo upgrade, thinking it would be a better choice. Within a few weeks, I noticed that my cranking was slow and labored. It is almost seven months later, and I find myself having to randomly jump-start my car. Note: At first, I was concerned that my audio amps were not turning off properly and checked to confirm that everything was off. I think I may need to go with a different solution now.
