Cashdollar2009 Posted August 11, 2011 Report Share Posted August 11, 2011 Quick question before i'm out for a while. I have been told by numerous people outside of the forum to look into using marine grade batteries. Locally I can pick up some batteries for around $100.00 a piece with what I felt were decent ratings in comparison to my old Deka 9a31's. Just looking for some thoughts. Also, the two batteries had ratings of 115Ah with 180 Reserve Capacity, as well as 106Ah with 215 Reserve Capacity. Which of the two would better suit me? So far Mechman is not able to make an alternator for my car and I don't necessarily just want to break the bank in batteries. Running the stock alternator and throwing the car on the charger every now and then, in a bank of 3 to 5 batteries, would I be more concerned with the Ah or reserve capacity ratings? Thanks all.

P4killer_ Posted August 11, 2011 Report Share Posted August 11, 2011 Well let me say this.. marine grade ie:. wet cells im assuming.. are frowned upon, but ive seen it done sooo many times and ive done it myself also. People will flame you over and over yet, that video of a DC 5k vs AB 500.1 vs Sundown 4500 was done on wet cells and they clamped 5k plus on each amp. on walmart bats.. which are deka made iirc anyway, the concern is the hydrogen gas they expel when charging... you can buy a vented bat box to vent the gas outside the car or build a vented enclosure for multiple bats, or do like in the cadi in above mentioned video and the trunk is sealed off from the cabin so the gas doesnt get in, and hes been running it like or i should say ran it like that fooor ever. on a bat to bat basis the wet cells likely dont hold a candle to xs but the price is also a big factor when you can run 3+ bats per 1 3100 just my .02 Quote Setup: 2010 Hyundai Elantra Factory Unit via 4 chan NVX LOC Excessive Amperage "H/O" Alt Xs D3400/ Xs XP3000 Big 3. 2 Runs of +, 2 Runs of - DD M3b and 2 12" AQ HDC4s Link to comment Share on other sites More sharing options...
Cashdollar2009 Posted August 11, 2011 Author Report Share Posted August 11, 2011 I appreciate the insight. I will be running either a single 18" or a pair of 15"s sealed off from the cabin in a trunked car setup on around 5k. (My Aveo) And price her is what caught my eye. For $500.00 I can run 5 of these marine batteries with the ratings that they have. I am stuck with my stock alternator so in order to run my DC 5K I want to have a good size battery reserve. I just got a new battery charger in January that I have yet to really play with. Second question, which specs should I focus more on here? Amp Hours or Reserve Capacity. As you can see, one ras rated 115Ah and an RC of 180. The second battery was rated 106Ah and a RC of 215. Thanks. Quote On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free.

skittlesRgood Posted August 11, 2011 Report Share Posted August 11, 2011 you want a battery that can discharge as fast as possible. you need that power in an instant, not over an hour.

Cashdollar2009 Posted August 11, 2011 Author Report Share Posted August 11, 2011 you want a battery that can discharge as fast as possible. you need that power in an instant, not over an hour. What is the specification I am looking for then, besides word of mouth on specific cells? Deka's have been marketed for I don't even know how long, with people selling them on the amp hour rate. Apparently Deka's are great batteries (9a31) but when Ah is the mainly given specification, and they are constantly selling off of that number... Not trying to come off as a dick, just want a more specific answer before I start planning. Quote On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free. Electrical energy is not.

skittlesRgood Posted August 11, 2011 Report Share Posted August 11, 2011 for audio, its not just the deka brand. its the deka intimidator that is the good battery. look at the discharge rate.

Discharge rate. That helps. Thanks. Now for example, what would be classified as a good discharge rate per say? I'm about to do some research now on the differing rates between a few different cells. Thanks mane. Quote On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free. Electrical energy is not. Link to comment Share on other sites More sharing options...
kirill007 Posted August 11, 2011 Report Share Posted August 11, 2011 the reserve capacity is too low. It needs to be atleast in the 600 for audio applications, you would be better off using 2 smaller xs batteries at the same price Quote Thinking is the root of all problems...

skittlesRgood Posted August 11, 2011 Report Share Posted August 11, 2011 (edited) the reserve capacity is too low. It needs to be atleast in the 600 for audio applications, you would be better off using 2 smaller xs batteries at the same price look at the deka intimidator as a reference. http://www.remybattery.com/Products/Deka-Intimidator-Battery---9A31__9A31.aspx Edited August 11, 2011 by skittlesRgood Quote If I answered you in a well mannered, informative way, you asked a good question or had a good attitude.

Cashdollar2009 Posted August 11, 2011 Author Report Share Posted August 11, 2011 Yeah I ran two 9a31's on my Crescendo 3kwp for a while at .5 and they did pretty well. Had to sell them a while back and the guy I bought them from online disappeared so... Where would I look to fond the discharge rate on these? I wasn't sure if the rating's I was looking for were on the page you linked. And also, I saw the 600 and wasn't so sure. lol I'm going to look for those discharge rates now seeing as one of the local marine batteries had a better Ah and RC rating... I'm looking for discharge though. Quote On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free. Electrical energy is not. Link to comment Share on other sites More sharing options...
