Battery OPTIMA or OEM Volvo

You don’t need to program anything to install a battery.. 2019 s90 if u want to save some money make sure u have the correct battery install at your local service center

My replacement was a Blue Top 34M and it's 8 years old. No issues with Optima here.

I've had great luck with the Optima Yellow Top DS46B24R for Gen2.

I've run Optima red tops for years and never had a problem.

Ended up finding a red top in the back of the store at Advanced (34R with 800CCA). If you go with Optima know that it takes some modification with the wiring. I needed to remove a cable tie and relocate one of the positive leads. Outback started right up and is running great.

I had a Yellow top optima installed for my subaru around 2015, it lasted until just today - held out well

The battery is an Optima Yellowtop 5.5 75h, I changed it in 2018. It has central poles and the negative pole near the windshield. Now given the very high prices of the Optimas and since their lifespan disappointed me, I wanted to get a cheaper battery.

Optima batteries suck as of the parent company’s sale about 10 years ago. Dead battery rate tripled in our fleet of cop cars (used for driving instruction).

Think my optima red top is about to give out, it's draining down overnight in the cold

I used an Optima, never again.
