I know some people love to shit on Optima but my yellow top is still kickin at 10 years old. Been run to the ground a couple of times over the years and the slow charger brings it right back.
I run yellowtops in my car and truck and the truck is going on 5 years now and still kicking.
I have have good luck bringing sulfated Optimas to my local Interstate Battery. They’ve brought several back from the dead for me and they went on to last a very long time.
I got a red top optima, put the subaru battery blanket on it. Good down to -10f.
Optima Red Top has been treating me well.
My battery in my Toyota echo is from Toyota and it’s like 12 years old and still starting at -35C so I’d say go with Toyota genuine
The yellow top is what I have in my car and there is one issue I have with it, the amp hour rating. The yellow top is only 38a/h where the OEM is about 45a/h. This will lead to the inverter using a lot of energy charging the 12v battery and decrease fuel efficiency.
I'd be more concerned about the Optima battery - they have been crap quality for years now. Probably better than VW OEM junk though.
Purchased one a few years ago, bad a year later and yes I have a good battery tender.
The "new" Optima in my RX7 died after a very short life
