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.

Pros: long lifespan (7 years), flawless cold starts
Cons: sudden failure

You can get an Deka AUX18L from batterymart.com for $159 shipped to your door. Deka is the OE manufacturer of the BMW battery for the i3. My original battery lasted 7 years, it’s a no-brainer.

Pros: lasted 7 years
Vehicle: BMW
Part number: AUX18L

However, the choice that I currently consider most balanced in terms of performance/duration/cost is the VARTA Silver Dynamic AGM 95Ah.

Pros: balanced performance, duration, cost
Vehicle: Alfa Romeo Giulia

Aracım 2012 model 1.4 tsi golf 7, aracımın güncel aküsü artık dipleri oynuyordu, marşı 3-4 defa basınca alıyordu, bende bu sebeple aküyü değiştirdim, aynı şekilde mutlu akü yerine efb start/stop destekleyen varta aküden 72 amper aldım, önceki akü de 72 amperdi. Aküyü taktık ve de yakıt dibin dibindeydi, gittim benzin aldım ve aldıktan hemen sonra epc ışığı yaktı, araç epc’yi yakınca gaz yemiyor, max. 20 km’yi geçmiyor. Gaz kelebeğini temizledik, yakıt deposuna kurum temizliği için ilaç döktük ilk etapta söndü ama tekrar yaktı. Ecu’dan aküyü tanımlatıp beyin sıfırlaması yapılması gerekiyormuş sanırsam, bunu henüz yaptırmadım yarın yaptıracağım ama bu aküden sebep midir? Eski o bitik akü’de bile böyle bir problem vermemişti.

Cons: EPC ışığı yaktı, gaz yemiyor, hız kısıtlaması, eski aküden kötü
