Battery OEM Nissan or OEM Subaru

Subaru OEM batteries can be pretty shit in cold weather. Even the service department at my dealership admits this. I eventually fed up with my Subaru batteries chugging in cold weather and replaced them with Interstate AGM batteries (with more CCA). I haven’t had any troubles since.

Subaru are known for using cheap batteries, winter just makes it even worse. within the first 2 weeks of buying a 2022 Outback, i junked the battery and put in a great aftermarket one.

Wife’s Ascent had a factory battery that last maybe 2 winters. Replaced it was a yellow top and haven’t had any problems since. Subaru even gave us credit for it so that was nice

I'm still running on the original battery, which does surprisingly well until subzero temps set in, and then the poor thing just cries a lot and breaks my heart, so I jump it with my Noco and things are fine.

Any tips or advice before I fork out money for a new battery? I have some anxiety hoping its not the alternator dying, or less likely the starter. All things point to a slowly dying battery but I want a second opinion.

I got a battery from Nissan under warranty. It has a 7 year 84K warranty if I recall. That battery less than 6 months later gave a fault and they replaced it again. '22 SV

the oem nissan battery had been replaced about a year prior, and it died in my driveway. the oem nissan batteries are crap.

I went through the same last month. 2019 Nissan LEAF I bought as a Certified Used Car from a Nissan dealership out of state last year with only 6,998 miles on it. They included the Nissan Factory Wrap warranty and I also bought an extended power chain warranty ( with a really good discount) too. My car was 52 months old when I experienced the No Start condition due to the 12 volt battery.

I had this happen in my 2020 outback around 37k miles. Dead battery was the culprit. Fortunately I shut off all my electronics and lights and it had just enough power to get it to restart. I got the battery replaced by Subaru under the extended 5 year warranty from a settlement for premature battery failure. It failed right after my 36k service at the dealer I think the car was about 4 years old at the time.

This happened to me during rush hour on a busy street! 2020 Legacy, they told me it was a known issue with the battery and replaced it for free. It was an incredibly stressful morning though.
