Battery OEM BMW or Duralast

For about a month I have owned a 2016 REx whose 60 Ah battery is supposed to get 72 miles. This week I fully charged it and have been commuting four four days without topping up. Today the REx kicked in with the trip meter at 73.3 miles. This was a mixture of city traffic jams and short bursts on the carriageway, mostly with the air con on and mostly in Comfort mode. So I'm pretty pleased.

I had my battery moment on my 2011 Outback, I bought a Duralast Gold 640 CCA and it's been working fine ever since.

Just replaced a Duralast (Autozone?) yesterday in my Silverado. It was from 11/09. It had a pretty good run in several vehicles of mine.

Went to Autozone and purchased there Duralast platinum, full 5 year replacement warranty for around $145. I installed it myself and had to reset the windows. Great since.

I am still on my original battery in my 2007 335i w/ 87k miles.

I ended up purchasing a Duralast Gold from autozone. It's actually Manufactured by DieHard of Sears. it's money back for the first 3 years. you get half your money back if it dies in years 4 or 5. Oh well lets hope the Duralast treats me good.

2 weeks ago, I brought in a totally dead, 16 month old Duralast battery to Autozone. The girl threw some meter thing on the battery, saw that it was bad, and swapped it out for a brand new one.

AutoZone. their Duralast Batteries have worked so well out here in CO.. i have abused them and used them and they still run strong... My buddy drove 10 miles on just the battery when the serp belt broke on his 2.0 and the battery made it, no problem...

My 2.8-year old mk6 GTI OEM battery started to show signs of aging about a month ago. It took longer to start when the car is cold and finally it failed to start yesterday. I called VW roadside assistance, got a jump start and went to Autozone, bought a Duralast Platinum AGM battery with size H6/48 . More to follow after the pics.

duralast has giving me nothing but probs.
