Battery Deka or OEM BMW
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
Actually the Deka's usually test out at almost double their rated CCA, but the big thing is the capacity. with such a small battery, yeah it may crank out enough CCA to turn you over in the winter, but it will only do it for a much shorter time than a conventional battery.
Deka FTW..... Love mine, cranks my high CR engine over no prob....
I have the Deka ETX14 in my car. I've had no problems with it. It's the same as the braille only 100 bucks(or so) cheaper. I have a high compression 8v... but no stereo.
The Dekas have all tested on par with the Braille. In fact the January Dekas tested at 435CCA (even though they're labeled as 200cca). If you buy a braille you're getting a great battery with a great warranty. If you buy a Deka, you're getting a great battery, an even better warranty (north america wide deka replacement at any deka dealer), and you're paying 1/3 the price.
They are exactly the same. Deka is half the price though. I've used a Deka in my buddies G60 that makes over 225whp on an 8v head with a lysholm, and it works great.
