I use optima. Highly recommend it too
Hrp: Optima. Best batteries out there. Have only had 2 since 2001! Red top, yellow and blue. Red should be sufficient unless you've got mega stereo. 800 watts.
I have a ‘21 (Dec 2020) M3 LR AWD w/19”. I’ve put 52K miles on it so far. Generally speaking, I’ve seen very little degradation.
I bought a used 2019 LR in 2020 and my estimated range is 302 miles with 48k miles.
I've been running a red top Optima for about four years now and no complaints.
I know some people love to shit on Optima but my yellow top is still kickin at 10 years old. Been run to the ground a couple of times over the years and the slow charger brings it right back.
The yellow top is what I have in my car and there is one issue I have with it, the amp hour rating. The yellow top is only 38a/h where the OEM is about 45a/h. This will lead to the inverter using a lot of energy charging the 12v battery and decrease fuel efficiency.
my 2009 had an optima and it only lasted 2 years
I have only had poor luck with optimas
At 126,000 miles in 2016, we had the battery replaced with an Optima yellow top dry battery. It lasted around 2 years and was replaced in September of 2018 under warranty. Today, my car suddenly wouldn't start, and after getting a jump and going to Autozone, it showed the battery had zero charge. They didn't have another yellow top, so I got a wet battery, one of the only ones available. What sucks is I checked the warranty date and it expired 4 days ago. I'm quite disappointed that the average life I've seen with these are under 3 years.
