Battery Deka or OEM Volvo

Depending on the year/model of the car you might need to have the battery "registered" using a special tool after installing it.

Just do it yourself or find an independent shop.

So on P3 cars, this light appears incredibly often. But since you’re at the point of your car not starting, you need a battery.

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 Mechanic had me get non-AGM style from Deka. I have the dual battery setup, and have drained my spare a few times already and it’s out performed the previous brands.

I had a 2004 Volvo s60 with a battery that lasted 15 years before I changed it. The mechanics were impressed. Really helped that it was located in the trunk.

I really like the Deka ETX12. Point is these batteries are bulletproof. They last longer than any other battery I have ever gotten. I highly recommend them.

I currently run a Deka Intimidator in my rig and it's been problem free for 3 years now

Only things that went a couple months back was the EGR and a window mechanism. And the battery a year before.

Paid charging is problematic mainly because the T8 charges so slow. You'd have to leave your car at a charger for like 5.5 hours to fill the battery.
