Battery OEM Chevrolet or Deka

I've always had sucess with the Deka ETX-20L in the DSMs, two EVOs, a Saturn race car, and now the TT (most of them running on E85 which is hard to start on cold winter mornings). As long as you discipline yourself to not run accessories with the engine off, they are a great option!

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.

I got a deka 15 and i love it

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!

forget optima. Go with a Deka.

Deka. cranks every time
