Battery Varta or Deka

I got a deka 15 and i love it

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.

I'm running a Deka ETX 14 and us a battery tender jr. works great

The battery is very clean and the original Varta and the box is in tact. Car has about 42K on it, and has been in service for less than 3 yrs.

I had the ETX14 in my N/A R32 for over 2 years and only time it really drains down is short starts and stops from the afterrun coolant pumps running for 5 minutes.

I have the DEKA ETX20L it started my car in 15 degree weather... I leave the car off for 3 days out of the week and it starts right up... I've been using it daily for quite a while... it has died on me a few times but it was my fault for leaving the fan on.. I just recharged it and it has been fine.

just had a etx14 sat in car for over a month and started right up.

Prep the car... Prep the space... The new beatzzz Deka Batteries... Clean as can be! Hot damn clean wiring!

forget optima. Go with a Deka.

Deka. cranks every time
