Love the optima redtops, seem to last forever
Finally pulled the trusty old Panasonic battery out of my CX-5 and replaced it with an Optima Yellowtop. When I buttoned everything up, I still had my radio stations and settings right where I left them.
Buy a nice battery. I bought used 6 months ago and did a week of nightly research first, by FAR the biggest complaint was the battery going out or having constant low messages. I put a yellow top in mine a few days after getting it, not one issue this far.
I have an Optima Red Top battery in my 2006 Dodge Magnum that's at least 5 years old (probably older). It was heavily abused for years. Since then, this battery has been in my daily driver (5.7L V8), and it's still cranking strong with no issues.
I put an Optima Red Top in it when my tester showed it below 75% health, about a year ago.
Get the battery from the dealer. It lasts longer and has a 7 year warranty. The Optima Yellowtop died on me after 3 years.
I bought an Optima Red Top battery for my van, but the part store accidentally got me the one with top mount terminals only instead of top and side like I requested.
Fwiw optima batteries have been garbage for the last 20 years.
Spouse has a 2021 etron, (some issues, inc battery recall), I had a 2022 etron with many issues which prompted my change to a 2025 SQ6. I’ve written to Audi Canada so many times regarding the etron issues with no resolution on any of them. I like the SQ6 but this will be my last Audi - worst experience I’ve ever had with any vehicle and manufacturer.
Optima batteries are absolute trash for deep discharge use. Their quality is also not what it used to be. Anytime I see them in marine use, I swap them out for a proper AGM. Only thing they are decent at is starting applications in cars.
