I put a Japan made energizer 2300mh storage at least for 8 monts, charged before storage and surprise, they make my flash work very quick even at maximum power, recycling flash time is even better than manufacturer specs.
It's a lovely car, but very bad on the efficiency. We have a 55 and the range varies from 150 in the winter to 250 in the summer. Honestly, for the money you'll struggle to get more car, it's very comfortable, quick, and has mountains of room inside. Ours is a 2019 on 70k miles, and has had zero issues
I typically use what is shipped with the packaging. Most of my red dots are trijicon and they ship with energizer so I will continue to use it. I feel the companies do their own testing trail and error with battery life and usage at all power levels under all temperatures.
Energizer. Better QC than Duracell imho.
Duracell lasted 18 months on my RMR 3.25 Type 2 on auto setting, Energizer lasted 23 months on same setting!
Having ran both Duracell procell, and Energizer lithiums in RMR's, the energizers last 3+ years. I've gotten 2-2.5 years out of Duracell.
I had same issue with energizer batteries both lasted exactly 14 months. Luckily battery came with18 months warranty so in total they lasted 28 months.
I drive a 15 year old gas powered Audi Q7. Still runs like new. My issue with EVs is you can't just keep them tuned up when they're old. No matter how good of care you take of it, the battery will decay and lose capacity.
Spouse has a 2021 etron, (some issues, inc battery recall), I had a 2022 etron with many issues which prompted my change to a 2025 SQ6. I’ve written to Audi Canada so many times regarding the etron issues with no resolution on any of them. I like the SQ6 but this will be my last Audi - worst experience I’ve ever had with any vehicle and manufacturer.
It is a great car to drive.\n\nThe battery range is very, very poor. On a cold day the range may be in the 120 range. It is exp naive to maintain as most parts on it are coded which means Audi dealer only
