Is there a big difference between AGM batteries?

[Wick76]

I have read all the threads about the differences between the automotive/marine AGM batteries and the car audio specific batteries. My question is about agm batteries in general. I have seen some 12v AGM that are marketed for solar power banks. Are these just a normal AGM battery like the ones you can buy at any autoparts store, or are they actually different? It is hard to find info on this topic.

I have seen test's on here somewhere where someone tested there spl set up with I think 5 different agm batteries all group 31's. his scores were all with in .2 db of eachother I believe.

Battery technology isnt exactly new, good companies use good materials. my favorite AGM for the price is DEKKA I am sure there are better, but dance with the one who brung you!
