None of the "special" car audio batteries will work because the shipping for these are like the price of the battery itself (at least the places that I've seen).

What exactly are the specs that I'm supposed to be looking at as far as voltage drop for the load of the amp? Are AGM's the only batteries that will really work?

The website "PowerStrideBattery" has free shipping to Alaska and I was looking at this battery "Odyssey 34R-PC1500T". So would 2 of these be sufficient for the saz-3500 (and probably the saz-125.4 later on)? Or can I go smaller or will I be forced to go bigger? These would also be the starting batteries and I would like 2 of what ever type of battery I get because of how I'm installing them. Thanks in advance

BTW sorry but it wouldn't let me post a link to the battery...
