You may be better off placing two decent AGM batts in for 1k.. at the least a min. of a 34/78

B stock deka group 31 is going to be the best value if you can find one. Duracell platinum agms are the next best deals.

Yeah.....it doesnt even have an alternator.  Theres a 15 amp stator for charging.   Not gonna lie, im kinda concerned about that.

I got mine on ebay, $150 shipped each from a seller called something like batterymom. They aren't always available but check frequently. 

You can get duracell platinum marine group 31s from sams club for about $200 with a 2yr warranty or pay a little extra for a slightly longer warranty- like $250-260 from batteries plus.

This may last you a good hour possibly??Im not a 100%sure on that.It just depends on how well it is charged up before using and how much close to full tilt you run your system.Id recommend looking at a good class D effecient amplifier.

Im looking into reinstalling my system in the truck and looking at 6-8 of these.I think that Excide may be another battery to take a look at for marine use/ AGM batteries

That is a cranking battery, not a deep cycle battery. Cranking/starting batteries are designed for short high current bursts, not sustained high current draw and constant recharging. Deep cycle batteries are what you need for running high current electronics.

Its an AGM battery if you look at it. Cranking amps are over 1k. Most agms may have 750-1k Cranking amps, and 650-800 CCA with a res of 120

I have one these in an 8n tractor for the last 2 years and never had any issues with it thus far.Good battery. It will work in a boat just as well as I have a boat and have used it in it as well all day long.

When I recommend anything on this site, Its due to what I have used myself or do use/run/ install/ installed or have ran. No hear say or look things up to recommend. I recommend of what I have experienced myself to others not from what Ive heard or read

Just because its an agm batt doesnt mean its designed to run high current electronics. Using a starting battery on high current electronics will overheat the battery internally and will significantly shorten its life. There are differences in the internal designs between a deep cycle compared to a starting/cranking battery.

Even tho this article is about marine batts, the same context applies to car batts:

Have you used this battery yourself??Ive never had any issues with it.Over heating?? Never had any issues with it.I recommended a battery Ive used and never had any issues.Sure there are differences in ALL batteries. No design is the same. All manufacturers design batteries differently, just as TVs, vehicles ect.Even a blender. LOL
