[QUOTE="SPL15, post: 4652833, member: 594830"] The thing is WHY?? Just get two kinetiks, the prices I have found locally are cheaper per AH than Optima. My opinion is that Optima is overpriced marketing BS. If you want spiral cell, get an exide. Spiral cell hasnt been proven to do anything but to give optima a marketing point... The brand really depends on what your looking to do with your system. Odyssey, NSB, and the powercell and some others are known for the low ESR that gives better voltage drop when drawing instant high current for SPL. If your looking for better reserve capacity for parking lot pounding and playing moderate volumes for 2-track parties then get something with lots of AH rating. I dont look at reserve capacity at all. AH rating I think gives you a more realistic view of how the battery performs with different current draws over time. Either way, you want the lowest ESR rating you can get, this means you gotta pay lots o money compared to the other AGM cells. You can get a lifeline marine AGM battery thats got GREAT reserve capacity and cheaper than the rest, but for instant 300 amps of current, the voltage will sag more than the expensive brands. Most batteries are made to draw 20 or so amps for a long time cause that's what the market is looking for such as trolling motors, lights and such on a boat, powering a solar power application, etc. HOWEVER they dont perform when drawing several hundred amps in a millisecond though. High power car audio demands current in hundred ampere instantaneous spurts, the market for batteries that can do this is VERY small. This is why you pay a premium for batteries that can do this. In my experiance, optima is overpriced for what it is. Kinetik from what I have heard is better at long reserve times than for instant 300 amps. I run odyssey and they seam to be good at both high amp right now and long reserve times. But really any AGM is better than a wet cell for car audio [/QUOTE]
