Yes. Subaru batteries are hot garbage. Go third party all day. I stand by any AGM I can pick up at Autozone, since they stand behind the batteries they sell.
My dealer replaced the battery, updated the firmware and did a parasitic drain test.
Adding my experience here for others that may stumble upon the thread. I was having really bad+inconsistent battery life with my left and then right buds, where they would die in less than hour. I replaced the both earbuds original batteries with the Varta CP1254 A3 battery and also did a hard reset.
It took a little over an hour to do and finally the battery life is decent again. I was able to run them for a good 3 hours on noise canceling with max quality settings and it's a night-and-day difference.
I've had some good luck with OEM Vw therye where either Varta or another OEM factory battery. 7 years on one...and also 3 years till 50%, lots of variables, to make a battery last or not last.
I just now successfully replaced the battery with a varta cp1254 a4 due to the right one going bad after a year of use, testing it for a few hours now and it worked!
I've been using the varta cp1254 a3 (60mAh) in my left earbud for about a month. The difference is very small (less than 10%). From full charge to low battery warning, varta 20%, zenipower 25+%.
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.
Subaru's factory batteries suck. I've had to replace them in several Subaru's that were only like 2 years old. Doubly tough if the car is just sitting for a period of time between uses.
I had Subaru batteries last me only 2 years in upstate NY. I kept getting them for free under warranty. I probably got 4 this way. Finally, the dealer said your alternator is bad and that's why they are going bad (completely bogus). I started going to a local mechanics soon after that and they told me that super OEM batteries are complete garbage.
Got a Varta battery and it only lasted 1.5 years. My car is parked under the sun on weekdays but was expecting more from the battery
