CJ18 Posted January 23, 2011 Report Share Posted January 23, 2011 AMI, You seems to have the most knowledge about the batteries and reserve capacities, can you please explain what the reserve capacity is and what it means for a car audio application. Also when considering what battery you want, you need to consider if you are building a daily driver you need a battery with a high reserve capacity and if building a competion(burp) vehicle, you need a battery with a fast discharge rate.

CJ18 Posted January 23, 2011 Report Share Posted January 23, 2011 Here are some explanations I have found about Reserve Capacity. What is reserve capacity? Reserve Capacity, (RC) is a battery industry rating, defining a battery's ability to power a vehicle with an inoperative alternator or fan belt. The rating is the number of minutes a battery at 80 degrees F can be discharged at 25 amps and maintain a voltage of 10.5 volts for a 12 volt battery. The higher the reserve rating, the longer your vehicle can operate should your alternator or fan belt fail. 3) RESERVE CAPACITY What does the Reserve Capacity rating mean and how does it apply to deep cycle batteries? ANSWER: Reserve capacity is the number of minutes a battery can maintain a useful voltage under a 25 ampere discharge. The higher the minute rating, the greater the battery's ability to run lights, pumps, inverters, and electronics for a longer period before recharging is necessary. The 25 Amp. Reserve Capacity Rating is more realistic than Amp-Hour or CCA as a measurement of capacity for deep cycle service. Batteries promoted on their high Cold Cranking Ratings are easy and inexpensive to build. The market is flooded with them, however their Reserve Capacity, Cycle Life (the number of discharges and charges the battery can deliver) and Service life are poor. Reserve Capacity is difficult and costly to engineer into a battery and requires higher quality cell materials. For instance, Rolls, Surrette and Lifeline use thicker lead grids (the plate's skeletal structure) to support additional positive plate oxides which are compressed into a denser form in order to add battery reactive material for greater Reserve Capacity and Cycling Performance. In addition, these plates are separated by indestructible separators. These mats hold the active oxides tightly in place during the cubical plate expansion which occurs during deep discharging, instead of allowing the oxides to shed off and precipitate to the bottom of the battery. Construction materials such as those raise the Reserve Capacity of a battery and increase the battery's Cycle Life. Link to comment Share on other sites More sharing options...
soundzright Posted January 23, 2011 Report Share Posted January 23, 2011 An optima yellow top group 34 battery is 120 and a XS power D3100 is 240, obviously we know which is the better battery of the two, but those are the numbers to look at for car audio application. specs on the xs site says for the D3100 RC is 110min that is the Ah rating is 110 the specs on the site have it labeled as RC now, i confused I think they got something messed up cuz I know the d3100 capacity is 110 Ah and reserve is 240. Wow that puts it equal to a pc2250 ran down to 10.5 volts. How much faster would a smaller battery wear out doing this? Link to comment Share on other sites More sharing options...

FaTbOy911 Posted January 24, 2011 Report Share Posted January 24, 2011 Nice Had an estimate of 6400 for an alpine/clarion setup dealer said it "should" hit around 160db with the custom boxes he was going to make for me..doubtful with so much area to move but, budget is way below that any ideas on cheaper brands for that kind of Spl setup? really didnt want to try any Boss or soundstorm, thinking Quantum figure around $150 per speaker "$1800 total" and $1700 to power it, first actual big setup for the van.
