Battery OEM BMW or Duralast
I set off to test the X5 battery to see if degradation was better or worse than my iPhone's 10% degradation over one year. We've driven 29,996 miles, 15,296.5 electric. My best all-electric range achieved was about 41 miles when new. After one year, I achieved exactly 41 all-electric miles from a full charge in ideal conditions. Zero percent degradation as measured by this test. It appears temperature and AC/heat use have much greater impacts on range than actual battery health at this stage. Results look better than expected for long term ownership and residual value.
I'm about to replace the battery on my 2013 acura tl 3.5L, looking for some advice on choosing between two batteries. The two batteries im looking at are the ACDelco Advantage 24FS or the Duralast ProPower Plus 24F-DL. They are similar in specs, same CCA though the duralast does have about 100 more cranking amps and 17 minutes more of reserve time. The acdelco comes with 18month warranty while the duralast has 2 years.
The other one (duralast one) has a better cca and will perform better in the winter months.
This is really straightforward to do. I replaced mine last September and was concerned about coding or needing to go to the dealer. My 2017 required none of that. Just take the old battery out and put a new one in. You'll have dash lights on afterwards, but all you need to do is turn the wheel all the way to one side and then the other.
I replaced mine in my driveway with a same size AutoZone Duralast Gold. With a coupon, I was out the door for less than $200. The car wintered outdoors at a Vermont ski resort and always started.
I JUST replaced my wife's 2013 Beetle battery with a Duralast from Autozone.
I used the duralast from autozone.
I use duralast and get about 4 years on a battery. No complaints at all.
If you actually worked at AutoZone and knew anything you know the duralast golds are decent.
I had a duralast battery that I had originally bought for my beater mk2 that ended up in the Corrado, it then let go last week after only 11 months. I would go with the Bosch at all costs.
