Battery Varta or OEM BMW

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.

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

Halt nur die Klassiker, alle 15j mal eine Batterie tauschen oder die wasserpumpe.

But during the ownership i found it really reliable, the only things i needed fixing were: battery (it was the original one over 7 years old), tyres and brake discs/pads (consumables on any car) and the regular oil/filter services.

The battery is most likely to outlive the rest of the car. No need to worry. If the car has enough range for your daily need, then keeping it will be the best option.

The only issue we’ve had with it is recently a bunch of warning lights started popping up randomly but all at the same time. I assumed it was a wiring issue or something since none of the systems it said were disabled actually were. Dealership couldnt replicate it so it took a couple weeks of bringing it back and forth every time it happened before they were able to see anything on their end. Replaced the battery and it’s been fine since.

My new BMW X3 was reliable.

It reliably would NOT start whenever the temperature dropped below -20C, even with a battery tender on it. The dealer couldn’t find anything wrong with it.

The battery lasted about two years. I had a company car at the time and only drove the BMW on my days off, and didn't drive long or far. The short, infrequent drives basically never allowed the battery to completely charge, resulting in it's early death.
