Battery OEM Nissan or OEM Subaru

Still going strong on OEM battery after 3yrs

I’m in the UAE, where summers hit around 50°C. This Forester is my first car with auto start-stop, and I’m impressed that the battery lasted a solid 4 years. With my driving habits (lots of short runs), my previous cars’ batteries would barely survive 1–1.5 years. This one lasted more than double that.

Still on vanilla battery. As part of my wife's start process is start car, press button to turn off auto off. Seems to be working.

Our car straight up died on the road twice, to the point it couldn't be jumped, with my kids in the back seat. Subaru eventually gave us an upgraded battery.

2013 Leaf! We loved it but the ~90 mile range made it a work and home only car.

We had a 2015 Nissan Leaf EV back in 2018. Fun little car but it only has an 80 mile range.

I’m on my third battery in my 2018

My battery died on my ‘15 Outback within a year of my buying the car brand new off the lot. I noticed some issues with the lift gate and the car was having problems starting at times. It was a bad cell in the battery so it needed to be replaced.

I had this issue as well, one day the car wouldn’t turn over. Then it would. Then there was no power. Then it would start. Over several days and weeks this would happen. It was explained to me that the Subaru batteries that come from the factory are made to hold just barely enough power to start the car. If that power is diminished in even the slightest degree, like with normal usage in the first 50k miles, then the battery does not have enough charge to do its basic task anymore, rendering it useless. As I understood it, the batteries in the new cars are not up to snuff.
