As a harley tech I see more aftermarket batteries fail then I see oem ones fail. There are a few good aftermarkets like DEKA but for the most part aftermarket batteries seem to fail quicker then oem.

My 2019 Mazda 3 died on me randomly a couple months ago. The dealership ran a test on it and it came out fine. I changed it anyway as it was a stock 5 year old battery. It’s been fine since, even in the -20°C temps where I am.
Odyssey makes the best. Optima for a middle end battery.
I just replaced the battery on my eco drive from maybe 2008ish? Battery itself was 14 bucks on ebay, oem brand(Panasonic). Swap took 5 minutes.
I have used exide battery+inverter for >10yrs and is still going good!
The only issues my wife and I have had on our 2021 CX9 and 3GT are dead battery issues. And we had dash and reverse cams fitted, which run and film continuously. If our street is busy, they can run the battery flat within 2 days.
I purchased one because of my car stereo upgrade, thinking it would be a better choice. Within a few weeks, I noticed that my cranking was slow and labored. It is almost seven months later, and I find myself having to randomly jump-start my car. Note: At first, I was concerned that my audio amps were not turning off properly and checked to confirm that everything was off. I think I may need to go with a different solution now.
I recently got one, somehow it feels less. Idk if it’s because of the software but it seems to be draining even while being idle. Which is weird. People are quoting 7-9 hrs of sot and i feel like am not getting anywhere near that.
