Battery ODYSSEY or OEM BMW

BMW here. No issues.

Tried them all at some point and whatever BMW OE does to those they last 2-3X longer. I literally just replaced a 14 year old battery last September….fuckin insane longevity with the OEM ones.

I bought the Odyssey battery and it's been well worth the money

Odyssey makes the best. Optima for a middle end battery.

If willing to pay for a Optima yellow top, I suggest you get an Odyssey battery instead. It's a much better battery for about the same price.

I’ve had my iX for 2.5 years and have logged 122k miles. I haven’t noticed any degradation in battery capacity. Just the normal summer/winter fluctuations (live in Midwest).

I finally spent the money on an odyssey extreme on my 7.3 along with an aftermarket starter and battery cables. Absolute game changer in the wintertime. I could leave it out in the cold for a week and it would start faster than the old battery setup would in the summer.

I’ve ran odyssey in my RZRs and they always held up through abuse and neglect.

I also just had a new battery installed by BMW, $600 for the honor.

my bmw would say this, a year after having a new oem batt installed, and only in the winter, dealer couldn't find the problem, so I traded it in for another subaru because parasitic draws are the last thing you want in a german car
