Battery Energizer or OEM Subaru

My dealer replaced the battery, updated the firmware and did a parasitic drain test.

I just ordered the energizer lithium fob battery, will see if it lasts longer than the regular energizer which in my case was 3 years

I didn't get long lasting power from "any brand name". Switching to Energizer or Panasonic did much better, like 2 years.

Now I stick to Energizer Max batteries, they claim a 10 year shelf life, and I have some that are 5 years old that are still near 100% state of charge, with no leaks.

I had an Energizer battery last 13 years in my ranger. Problem was when it came time to change it I couldn't find them anywhere.

Mine went at 32K...just crapped out on me one morning. Luckily I work part-time at a Tire/Battery Garage. Put in an Energizer group size 47 (as stated above)

Subaru has had a problem with their electrical systems since 2014. Batteries last 2 years, max. 2018 legacy is on its third battery in 4 years. 13,000 miles. $600.00 in batteries.

Subaru batteries aren't great in the cold either

My battery made for Subaru died on my 2017 Forester 2 weeks before the warranty ran out. SUBARU has their own problems with their batteries.

Subaru batteries suck
