Running two XFL 15's off of 3000 or 4000 watts. ( havent got an amp yet). What size battery do i need. Like to pick on up local. I was told 100 amp Deka but i got no idea what that means. Is that cranking? Total? Need help kinda soon.

i think the general rule of thumb is 55ah per 1000 watts so about 165-220 ahs.

O'Reiley's auto parts' premium AGM battery is built by Deka. Also consider the Sears Die Hard Platinum AGM style battery. High quality and very good warranty. AFAIK Sam's Club also has a "Duracel" brand AGM battery made by Deka. Get a couple 105 to 110AH size and you should be pretty good.

well how many amps is your alternator? The more power you can generate with your alternator, the less power you have to make up for it with your batteries

Naa man, they're talking about 100 AMP HOURS; It's a different kind of rating versus Cranking Amps / Cold Cranking Amps; At a Minimum, you will likely need (2) Kinetik KHC2400's, possibly even 3;

Found two deep cycle marine batters with 200 Rc (which i believe is 100 Ah) at Orilleys for $95. Would that work?

Make sure they are agm. At that price i doubt they are ..the agms at oreilleys will be between 140 and 190 each depending on size
