Battery OEM Mazda or OEM Volkswagen

Had my '18 R since May '18 and still on original battery, 25 mile commute to work each way about 1/2 hwy . At 57,000 miles.

OEM battery in my 2016 Jetta with 215k miles is still going strong.

In Mar 2022 I went to the dealer and got a new VW battery for my GTI $151. Not knowing any better, I simply swapped it in the parking lot - I did use a OBD-II device to keep circuits alive while the battery was disconnected. All worked like it should.

2014 Mazda 3, about 65k km.\n\n2nd battery only because I left the lights on one time a few years ago and needed a replacement. Nil problems otherwise.

2018 Mazda 6 is going fine.\n\nProbably due for a battery soon as preventative maintenance.

Battery died July 2022. So got 3 years out of it. New battery is AGM (OEM VW from dealer). Stock battery was not AGM.

The OEM batteries are shit. It died around the two-year mark.

My battery died last July at exactly 2,5 year mark. Mazda OEM battery is a cheap trash and so are the replacements too.

My 2014 CX-5 eats batteries and always has since i bought it brand new. I usually have to replace 1x a year\u2026 and I know it\u2019s coming about 45 days in advance because my bluetooth and USB chargers will suddenly stop working and that\u2019s how i know oh my battery will die soon!

I have the same problem with my Mazada 3. Changed the battery while still under warranty and still does it. I don't leave anything pluggeded in and it still dies overnight. I purchased a battery tender and have to hook it up every night or get a boost in the morning.
