Battery Energizer or OEM Subaru

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.

I typically use what is shipped with the packaging. Most of my red dots are trijicon and they ship with energizer so I will continue to use it. I feel the companies do their own testing trail and error with battery life and usage at all power levels under all temperatures.

Energizer. Better QC than Duracell imho.

I had same issue with energizer batteries both lasted exactly 14 months. Luckily battery came with18 months warranty so in total they lasted 28 months.

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.

Replacing my battery recently

A new battery at 10k miles.

Battery died around 50k miles.

My 2020 Outback OEM battery only lasted 3-ish years.
