Battery replacement

Don't buy the Interstates! Buy Deka AGM 240 each I think or less.
Interstates when the company bought Johnson Controls many years ago now and just up the road, started making the Interstate brand after a year made them with thinner plates etc but their marketing was great. On my daughters truck I replaced Interstate batteries from Wal Mart about every year.
Wife stuck on the side of the road with factory batter about to explode, north of Atlanta, in 2018 bought an Interstate from a gas station down the hill from the road. 2019 it went bad and in a series of event cascaded into $4,000.00 in repairs the batter would not hold a charge and in Shawnee, Oklahoma, the Parts stores would no replace it because the mechanic did not punch out the date of purchase, unknown to my wife. Johnson Controls makes a lot of batteries under different names and quality, and I have no idea which one to recommend if any. Teh battery n my AMG is over ten years old, I don't know the brand and hard to get too. I find out I may put them in my other vehicles.

Most automotive batteries made in America are manufactured by one of two companies: Johnson Controls, Inc. or Exide Technologies. The dominant replacement market brand names, Interstate and DieHard, are both Johnson Controls products, as is the Optima brand.
Usually the batteries are the same except for the badging.

You can save some money buying DEKA GC2 6 volt batteries from places like Batteries Plus and others. The DEKA and the Interstate are both made by East Penn Battery Corp.
