Battery experts needed. Looking for spl battery and need help understanding specs.

[dtbrown 10+ year member]

Been comparing some batteries for Street A and looking at specs and wondering what is the most important thing that I should be looking for?

What specs should I be looking at and what specs don't matter. This is for spl competition use so I need input from someone that really know what they are talking about.

In the battery size I'm looking for I've seen amp hours from 72-100ah at 20 Hr rate. Do ah (amp hour) really matter for spl use?

Or does CCA? I've found anything from 760-930cca but the battery with the lower CCA is 8 lbs heaver and has 20 more amp hour than the higher CCA that is lighter. But both batteries have same short circuit amps. That leads to my next question.

Or does short circuit amps matter? Everything I've found is about the same at 3300 amps.

And what is better and why, AGM, Sealed lead-acid or sub-colloid gel battery?

Any help would be appreciated.

I look for short circuit amperage in gel based Valve Regulated Lead Acid (V.R.L.A.) batteries for my 12 volt spl setups. Im using broadband communications batteries (similar to the batteries that you'll find on the top of electrical service poles in those metal containers you see on your street corner for CATV and broadband internet communications.) They're designed to take a quick current draw when power is lost. Ive got 6 of them in my Jeep, and ive never had a power issue. And my amplifiers pull 650+ amps for burps, with the voltage hanging around 12.5 during the burps. The short circuit on the MCG-120's that I use are 5300 amps.

This is the exact battery I use : http://www.powerbattery.com/pdf/broadband-broc.pdf

if you want to take a look at my setup to illustrate the size, here is a video :



hope that helps

Not much of an answer but thanks for trying. And Kinetik, Deka are AGM batteries and optima yellow is sealed lead-acid but the blue top are AGM.

Funny that you brought them up. I was also looking at that company but in a different version. Thanks

From my experiences, I used to run an nsb75 for daily and ended up killing the battery in 3 months. However some people have better luck out of them. From there I went to powermaster and I haven't had a problem since. They do great for daily and for comps I recommend a powermaster D3100 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

You should get that NSB warrantied. They should replace it for you. But I was also looking at both powermaster and NSB. I can't get something as big as the 3100 but the 2700 will work for my class. thanks

Yah, but now street A is limited to 650 cubic inch battery. So can't use any group 31's cuz they're to big. So far my choices are Kinetik 2000, NSB G2700, powermaster D2700. But sill looking.

You can't use a g31 yellow top in st a. it's to big. The powermaster 2700 is going to be a popular battery in st a.
