[QUOTE="SicAudio, post: 7200384, member: 609136"] quote all of it next time brah... 4. CCA, CA, AH and RC. What are these all about? These are the standards that most battery companies use to rate the output and capacity of a battery. Cold cranking amps (CCA) is a measurement of the number of amps a battery can deliver at 0 ° F for 30 seconds and not drop below 7.2 volts. [B][I][COLOR=red]So a high CCA battery rating is especially important in starting battery applications, and in cold weather[/COLOR][/I][/B].This measurement is not particularly important in Deep cycle batteries, though it is the most commonly 'known' battery measurement. CA is cranking amps measured at 32 degrees F. This rating is also called marine cranking amps (MCA). Hot cranking amps (HCA) is seldom used any longer but is measured at 80 ° F. Reserve Capacity (RC) is a very important rating. This is the number of minutes a fully charged battery at 80 ° F will discharge 25 amps until the battery drops below 10.5 volts.
