Battery OEM Chevrolet or OEM BMW

Mine is ten years old. It's a Chevy volt so it's a small battery and has over 3000 cycles and done 130000 km. It's at 87% original capacity.

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 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.

Same with my 2008 BMW 535d. 900ah and still going strong

I had a battery in a 93 BMW last forever like that

Regardless, while that’s sorta old for a battery, I have OEM BMW batteries going on 12 years with 89% charge capacity.

These were very very well made batteries. They also used to be insanely expensive. Now, BMW knows the game and offers a 2 year warranty, which is pretty low for batteries, but they are very competitively priced.

My 2021 45e usually gets 30-34 in mild southern US weather per charge.

What is the sound of one hand clapping? Does a bear sh1t in the woods? If the bear does, is the turd a uniform size and power that will work with attributes of all the other different sized bears out there?

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
