Battery OEM Mazda or Duralast

I recently got a Duralast Platinum battery and it has proven to be very good so far

The battery you want is an AUX18L 20ah battery. I used [This battery](https://www.autozone.com/miscellaneous-non-automotive/power-sport-battery/duralast-gold-etx18l-group-btx24hl-agm-ready-to-ride-power-sport-battery-340-cca/350084_0_0?spps.s=4782) myself a month or so ago, it is an ETX18L and it has been working fine.

I just replaced my OEM H5/LN2 group 47-sized battery with a Duralast Platinum H5-AGM Group Size H5/LN2 680CCA battery. After having my mechanic change the settings in the ECU from EFB to Fleece for battery technology, 60Ah for rated capacity and set the date of install for the last 8 digits of the serial number, all seems to be fine. It fits the OEM position and cover perfectly.

I've also had great luck with AutoZone's Duralast Gold/Platinum batteries and they have better warranty than most others as well.

My last battery was a Duralast Gold and it lasted 7 years.

The only issues my wife and I have had on our 2021 CX9 and 3GT are dead battery issues. And we had dash and reverse cams fitted, which run and film continuously. If our street is busy, they can run the battery flat within 2 days.

I Have had the Mazda CX60 Azumi Tukami G40 Turbo 6cl petrol engine for 12 months now and have had this back at the dealership several times. I believe I have the lemon of the bunch.

Continual Istop issues, it has needed reprogramming twice. The battery has failed testing and needed replacing.

the stock battery only lasted 3 years. My VW prior lasted 7 on the OEM battery.

Battery died less than 12000 miles. Apparently Mazda is using cheap batteries, as this seems to be a common issue. But I still see others complain about the same thing.

first issue I had was the battery at around 2000 miles, it was replaced under warranty.
