vs
Battery SAMSUNG or Deka
Me too. Using a Deka ETX20 right now. Scooped it for $85 shipped from Tri-State Battery. I just got my car back on the road, so I haven't seen how well it holds its charge without running the car every day though.
Part number: ETX20
Great thread. I have used lightweight batteries in all of my builds. Dont buy Braille or any high end BS. They are all rebranded Deka. Ended up grabbing a etx14 power sports battery from autoquest for $70. Same as the Deka ext14 just rebranded.
Pros: works like a charm
Part number: ETX14
In sum, I can fully recommend the Deka ETX30L battery for long-term and continuous use in our cars.
Pros: long-term, continuous use
Vehicle:
Porsche
Part number: ETX30L
I have some extended experience with a lightweight battery in my daily driven 2006 Boxster S, which is well known for the demands it places on the battery. In spite of that, I successfully used the Deka ETX30L (21 lbs.) for almost 3.5 years.
Pros: reliable lightweight battery
Cons: trickle charger needed
Vehicle:
Porsche
Part number: ETX30L
EDIT: Confirmed fitment (duh) and ordered the Deka through Batteries Plus. This battery seems to be best fit as its reserve capacity is nearly double that of the Optimas.
Pros: best fit, high capacity
I have had excellent results from a Deka Intimidator 9A48 High Performance AGM Battery Deka / Remy part # 9AGM48 installed Dec 2010
Pros: excellent results
Part number: 9AGM48
I don't recommend anything less than the DEKA ETX-20L for a car that see true street duties. The ETX-14 is 200 CCA @ 12 lbs, and the 4 lbs weight loss isn't worth it for 70 CCA loss on a small battery in charge of starting a car. The ETX-18L does 270 CCA @ 16 lbs and much more suitable for our 4 banger application. The ETX-18 however is the one I recommend to 95% of readers of this thread. It cranks out 300 CCA at 18 lbs, which is still plenty light.
Pros: cranks out 300 CCA
Cons: 70 CCA loss
I noticed too, i mean, it's worse but it's not that bad, with the tab s6 I could do from 9 to 10 hours sot, sometimes even 12.
With the tab s7+ I can do 8-9 hours sot, so not that bad
Pros: 8-9 hours sot
Cons: worse than tab s6
I just upgraded mine a few weeks ago, ended up getting a DEKA AGM 9AGM47 More CCA and far more reserve capacity than the stock battery (120 mins) I was at ~35k miles and my OEM battery was failing fast.. I couldn't leave it in the accessory position without the engine running for more than a minute or two or it would barely be able to crank. The OEM battery is crap as far as I'm concerned
Pros: more CCA, more capacity
Cons: OEM battery is crap
Was getting similar specs as op when a few days ago it seemed to have just lost its amazing battery life.
Went from 4 days w/o charge to about 1.5 days.
Pros: amazing battery life
Cons: lost battery life
