Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Hi,I personally stick with the AC Delco brand and have found that the S57038EFB has been fantastic as it withstands constant unlocking of the car to maintain a charge of above 12V for dash cam use in parking mode. The standard S56838 and S57220 unfortunately aren't able to do that. However that's a very specific need and in general you won't go wrong with a standard 600 CCA battery like the S56838. Make sure
when you select a battery to choose the appropriate one with a vent to connect to the vented tube in the boot (there's a video on YouTube of some bright spark replacing his with a non vented battery that was also the wrong size).
But would like your advice since you raised a good point here, will the existing charging control circuitry/ algorithm suit these EFB TYPE BATTERIES if you go this deep cycle way?. Appreciate your thoughts or any one out there that knows the vf2 charging design.
Thanks for that...i will get one then. Yes its true in the ac delco catalogue for the vf2 6.2 lt they list a range of selected batteries and the spec shown for the efb version reads as a very high rate / endurance battery...thanks for the re assurance.Hi, I am no battery expert however I have now operated my S57038EFB since February 2020 and had 0 issues with operations and charging. However am still mindful when I open anything via my key fob, in particular the trunk as that seems to take the most amount of volts to just below the 12v threshold causing the dashcam to power off. Luckily both of my vehicles have the buttons on the doors, while I always open the boot via in internal button on the driver's door.
Also to note that my daily drive consists of slow-crawl traffic maximum 50kms/h (average probably 18km/h) for 20 mins one way so that is definitely not beneficial to the battery. I make sure that it is always charged to my Ctek MXS5.0 when I return home (and the EFB is charged as a normal battery, not AGM). Both the EFB and AGM options are listed as options via the AC Delco website for our vehicles so I can't see there being an issue (and I believe the Chevy SS for the American market got factory AGM batteries).
I just replaced the battery in my VF Redline Wagon, as my mechanic said the AC Delco battery in it will need replacing soon when he serviced my car.
Went to Supercheap Auto and ordered a Century DIN65LHX MF, which comes with a 40 month warranty, CCA of 760, and a reserve capacity of 145 minutes and is a 77 ah battery. Wasn't cheap, but, I have always been a fan of Century Batteries....
If it’s this one at $233 on discount, that’s a fantastic deal:

At 760CCA that is what the AC Delco AGM battery provides and I’m quite sure you’ll be spending a lot more than $233 for that one! Great one!
