I got just over 7 years from the factory Varta battery in my old 2015 MK7. It was the smaller H4 size and always started flawlessly in the Canadian winter. It ended up failing in the early summer. It cranked rather slowly one morning and the voltage refused to go above 12.3, even after charging. It barely started when I went to get the new battery. I was lucky enough to not get stranded.
I had to replace the battery on a 2016 Crosstrek this summer and, in retrospect, missed a bunch of warning signs before it finally wouldn’t start: slow cranking, occasional extra crank needed, flickering dash lights, and generally dim interior lights.
Got a Japanese one: Varta Automotive EFB Car Battery Q-85/115D23L 12v 70Ah 660A (EN) just over 1/2 the price of an Australian made Q-85. Got 6.5 years out of original from Japan 2019 using stop start most of the time.
Varta’dan vazgecmeyin. Zamaninda bahsettiginiz markalari kullandim 2 yil sonrasinda yolda kaldim. Kendi aracimdaki aku de Varta.
Clio 2014 aracım vardı s&s lu orijinal aküsünden sonra mutlu akü kullandım memnun kalmadım şuan Varta kullanıyorum çok memnunum ben yerinde olsam risk almam vartadan devam ederim
Very unlikely to be the starter, though anything is possible. I'd put money on the battery being weak though. Voltage isn't the end all be all, you need to know about the cranking amps.
I bought my wrx brand new in 2015, the battery lasted two years and was replaced at the dealership. That second battery lasted two years and I went back for them to replace it and said that they wouldn\u2019t because it was already replaced under warranty. She told me they would replace it for something like $160, I said \n\n\u201cLook lady the first battery lasted two years and the second lasted two years, I\u2019m not spending my money on your junk batteries.\u201d
21 Outback. Battery issues - I’m on my fourth battery since buying it. Have had issues with door seals leaking, but those were fixed easily under warranty. Definitely can confirm the assembly quality - we had to test drive quite a few before getting one that didn’t rattle on every bump we hit.
My Forester is 2021, already replaced the starter and the battery. The current battery starts to feel weak as well.
I will not trust having a Subaru battery in my Subaru cars, I only buy Walmart, Costco or Interstate.
