Battery OEM Honda 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’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.

Currently, a bit over 3 grand (labour included), at least for the Civic/Accord Hybrids.

Some of these OEM batteries they choose to use are shit.

530e with a little over 20,000 miles shows 10 miles electric range on a nice summer day. It used to show 15 when new. BMW said that the drop was not warranty worthy.
