Battery OEM Mazda or Varta

Thank you for this excellent write up. Made switching out the 11 year old Varta a breeze. Locally cold temps caused negative strap reconnect challege due to stiffness. That and the mass of the big AGM we're the main challenges.

My oem battery lasted from '08 to '13. The last few weeks the car would hesistate to start. The starter would click click, dashboard lights would flicker, and the ECU and CANBUS would reset. I'd lose the auto windows and see my trip odo reset, but the battery read 12.5V and alternator read just fine too. I waited until the day I had to jump-start the car then drove to VW and bought a new OEM battery; I believe it's a Varta. After I installed new battery the starting issues went away, but I got stuck where the car would go "clickiddy clickiddy clickiddy click" and dash lights flickered like mad; new battery too! I took my multi-tool and started beating on the connections, leads, and grounds. I found the ground wire to be a bit corroded. After cleaning the terminals with 120 grit and a whopping dose of dielectric, car starts like brand new. The starter is pretty tough.

Varta makes damn good batteries. One in my Rabbit lasted almost 5 years.

My GTI's original Varta battery lasted 7 yrs with normal driving/ number of starts.

I replaced mine also with the G14 and no problem at all, so it should work or your old battery broke becasuse of a defective module jorg

Here is a picture of the left battery that the factory put in my W12 when it was new. As you can see, it is labelled both 'Varta DE' and 'VW AG'.

I have mine VARTA battery since the car was made in 2006. Works like a charm. Great Batteries.

So far have not had any issues except for dud OEM battery, kriginal and warranty...

It was a Varta battery. And dial a battery and car guru provide similar services right? And I only talked about battery prices as the service to come to my place was provided via insurance. Secondly yes I accepted it as I had to go out in a hurry but in my opinion they seem to be expensive when directly compared to their competitors.

my 2019 GolfR battery died recently. well, it wouldn't hold any capacity and had to be charged every few days. anyway, i had my warranty apppointment today at the dealer and stood outside for an hour. i was wondering why it took so long. the new battery is a 000.915.105.CB.DSP. hopefully the AGM battery will do better with mine too.
