Battery OEM BMW or OEM Subaru
Reviews
OEM batteries are made from fairy dust. I still have my original one in my E92, made in 2007. Def recommend getting an OEM battery.
Pros: excellent longevity, original quality
Vehicle:
BMW
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.
Pros: long lifespan, good in hot climate
Vehicle:
Subaru Forester
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.
Pros: long lasting, working well
Vehicle:
Subaru Forester
Mileage: 120000 km
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.
Pros: problem solved, upgraded battery
Vehicle:
Subaru Outback
BMW here. No issues.
Pros: No issues
Vehicle:
BMW
Tried them all at some point and whatever BMW OE does to those they last 2-3X longer. I literally just replaced a 14 year old battery last September….fuckin insane longevity with the OEM ones.
Pros: long lifespan, excellent durability

Ich fahre im Moment nen BMW i3 von 2015 mit nur rund 15 kWh Batteriekapazität und knapp 80k km runter. Da die eh so klein ist und das Auto auch kein großartiges Lademanagement hat, knall ich (und wahrscheinlich alle Vorbesitzer auch) die Batterie eigentlich so gut wie immer auf 100%, was man ja eigentlich vermeiden soll. Das Auto liegt über den Daumen gepeilt ca. 10-15% (eher 10) unter den Angaben, die man so im Netz findet.
Pros: robuste Batterie
Cons: 10-15% Reichweitenverlust
Vehicle:
BMW
Mileage: 80000 km
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.
Pros: replaced under warranty
Cons: dead battery, premature failure
Vehicle:
Subaru Outback
Mileage: 59545 km
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.
Pros: replaced for free
Cons: stressful morning, known issue
Vehicle:
Subaru Legacy
I had this problem with my 2019 Forester in stop and go traffic on the Dallas North Tollway. I was able to force the car into park and shut it off and back on manually, and this happened about a half dozen more times before my dealer finally admitted that there was a class action on those batteries. I’ve since had it replaced two additional times under a labor warranty. Like I guess it’s fine because it’s free, but very annoying that I bought a Subaru for reliability and I’m in the shop at least every 9 months for a new battery.
Pros: replaced under warranty
Cons: repeated failures, annoying, frequent replacements
Vehicle:
Subaru Forester
