I've had great luck with the Optima Yellow Top DS46B24R for Gen2.
I had one with the battery that lasted just under 12 years.... Old original BMW batteries are built different! Especially if the car is driven regularly.
I've run Optima red tops for years and never had a problem.
Ended up finding a red top in the back of the store at Advanced (34R with 800CCA). If you go with Optima know that it takes some modification with the wiring. I needed to remove a cable tie and relocate one of the positive leads. Outback started right up and is running great.
I had a Yellow top optima installed for my subaru around 2015, it lasted until just today - held out well
Same with my 2008 BMW 535d. 900ah and still going strong
I’ve had an Optima Red Top in my 2012 JK Rubicon for about 8 years. My mechanic recently said the battery is on its way out, and now the Jeep is struggling to turn over. I’ve heard Optima’s quality has dropped since I bought mine.
20 years ago optima was good. Now its 300 dollars for a 50 dollar battery. Used to get them super cheap as a jci employee and they would last made in Colorado but the quality control has been gone for decades.
Yes it's overkill if you don't need it. Standard batteries are perfectly fine for 99% of use cases
It literally is of 0 benefit and in fact they have shown to have a shorter lifetime in these applications.
