I'm just an electrical layman, but I do like to see some evidence when someone makes an assertion. I'm not convinced by the evidence I've seen yet.
We argue seemingly nonstop on this forum about which is the best anchor, even when someone posts a video of their anchor "outperforming" other manufacturer's. Why should this be any different?

I am going to be uploading two videos I just made.
Customers bank of 3 Duracell/Deka group 24 batteries. Bank approx 2 years old and was end connected. Batteries are way out of whack. Rated at 550CCA
Battery #1 = 490CCA (the end connected battery)
Battery #2 = 553CCA (the second battery)
Battery #3 = 649CCA (the last battery in the string)
159 CCA difference between battery 3 and battery one at just two years old.
My own bank of Wal*Mart MAAX-29/group 31 batteries. Entire bank cost me $210.00.... Bank is 7 years old and was always wired in a cross connected manner. Batteries are very well balanced for 7 years old. Rated at 675CCA.
Battery #1 = 818CCA (system positive connection)
Battery #2 = 845CCA (middle battery in string)
Battery #3 = 820CCA (system negative connection)
27 CCA difference between best battery and worst at SEVEN years old......
The videos take a while to upload.....
