In sum, I can fully recommend the Deka ETX30L battery for long-term and continuous use in our cars.
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.
Purchased a Red Top 35 today and it fits! I did have to take the bottom bracket and flip it so that the side of the battery facing the headlight [+ -] stayed secure.
I ended up buying a red top optima gel battery....expeeeensiiiive
I had a red top in my mk5 after the OEM one took a dump. It worked very well without any issues.
been using optima redtops for almost 10years in all my vws. even when i was out of warranty they still let me take it in for a free new swap. theyre somewhat overkill for basic cars but w/e. i love them.
I've been running a redtop in my Outback for 8 years now. Still shows no signs of slowing down. Will be getting another one for sure.
I just threw in a red top in the G60 and it did not fit well at all. The optima website mentioned some sort of adapters that were supposed to fit on the long edges of the battery to make it fit better under the battery holder, but I did not get any with my battery. I ended up shimming it to get it snug.
Optima is not what it used to be. Total and utter crap.
Every optima battery I have seen in customer vehicles (I'm an auto tech) goes to crap in about 6 months to a year. I think these types of batteries are more sensitive to low voltages. They also don't hold up at all during the freezing winter months.
