Battery OEM Nissan or Varta

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.

The dealer sold me part # 000-915-105-DH for my swap yesterday. Sadly I didn't note the mfg and now that it's buttoned up we'll never know... FWIW - it looked almost identical to the Varta #1J0 915 105 AG that I pulled out.

Put one in my Frontier last winter, and had more consistent starts. Cost half of Nissan dealership with higer CCA.

As for the battery choice, I'd personally opt for the Varta. The main reason being the service life you have received from the original battery. I wouldn't worry too much about the Varta's lower rating as the original has seemed sufficient over approximately 6 years and most Phaeton owners are reporting excellent life from the original batteries.

Saturday morning, we pull up to the house outside of Palmdale to this scene - a beat ass Chevy Celebrity trying to jump start an even more thrashed Nissan Stanza. The battery was fully charged, but it wouldn't start because it was still in 'drive.' After almost burning the thing down with improperly attached jumper cables, we were ready for a test drive. It ran... kinda. It was firing on 3...sometimes 4 cylinders, and the oil was overfilled by about 2 quarts.

Service guy just stopped over and confirmed the battery was bad. Replacement installation in progress.
