When it comes to your high-performance vehicles, one of the most
overlooked upgrades is the battery. While the type of battery
under the hood is not going to shave any time off your quarter-
mile times (though there are some battery mods that will),
getting the best performance from your charging system is always
a good bet, especially if you have upgraded electronics. This
guide will break it down for you so the next time you need to
pick up a battery you will know which one to grab and which ones
to leave on the shelf. CA - Cranking Amps, this is the rating of
cranking amperage measured at 32 degrees F. CCA - Cold Cranking
Amps, this is the amperage rating the battery can provide at
0-degrees F for 30 seconds without dropping below 7.2 volts.
This is the most important measure of a battery, and is the
typical rating used for selecting the appropriate battery for a
vehicle. RC - Reserve Capacity, measured in minutes, this is how
long the battery will provide 25 amps until the battery voltage
drops to 10.5 vol
