Battery AC DELCO or Deka

I had an Optima 5 or 6 years ago but I heard the quality has went down and the warranty isn't as good as it used to be. I picked up a Deka intimidator deep cycle battery and It's by far the best battery I've owned.

But the best OEM batteries are definitely AC Delco, the GM ones. Routinely replaced them at 6-8 years, longest I ever saw was the original battery of a 97 Grand Prix that I replaced in early 2008.

I got a deka 15 and i love it

get an acdelco group 47 battery fits perfect is the identical size as oem and is probably wayy cheaper than an oem, i paid 85 idk how much oem ones are

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

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!

Switched to a stock mk5 4cyl battery though as the Deka couldn't handle sitting for more than a couple days without being on a trickle charger.
