Battery AC DELCO or OEM BMW

Been recently thinking that 100 packs of ACDelco for AA and AAA are the best value per watt usage

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.

Currently I have ac delco batteries in every car I own. I work at a Cadillac dealership though so I get good prices on them and they're good batteries.

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

The old battery I had in mine was an AC Delco, model ACD41-60 (I'm guessing size 41, 60-month warranty). Sticker said 685 CCA, 330 for charge. It's raining outside right now and I don't have any pictures of the sticker for my current one. The Delco battery finally died after being 8 years old. It showed signs of aging and being weak for about 3 months before that, and then one of the cells shorted out, so it had about a 5-amp capacity.

In our shop we have found that the professional line of AC-Delco batteries seem to last the longest. I believe if you check the AC-Delco was what was installed at the factory in your Suzuki, and that lasted 7 years.

I'm a big fan of AC Delco batteries. Every one I've had has outlived the cars I've put them in.

But the best OEM batteries are definitely AC Delco, the GM ones. Routinely replaced them at 6-8 years, longest I ever saw was the original battery of a 97 Grand Prix that I replaced in early 2008.

get an acdelco group 47 battery fits perfect is the identical size as oem and is probably wayy cheaper than an oem, i paid 85 idk how much oem ones are
