The battery stores energy in a chemical form that can be converted into electricity on demand. This electrical power is used by the vehicle's ignition system for cranking the engine. The vehicle's battery can also power the lights and other electrical accessories. In case the alternator belt fails, the battery can also power the vehicle's entire electrical system for a short period of time.

SIZE: the dimensions of your original battery.
POWER: the Cold Cranking Amps required powering your vehicle.
WARRANTY: Automotive batteries are backed by a warranty package. Choose one that is right for your vehicle's needs.

Before you start, always check the type of grounding system the vehicle has because if you remove the positive connector first in a negative ground system, you risk the chance of creating a spark. That could happen if the metal tool you' re using to remove the positive terminal connector comes in contact with any piece of metal on the car. If you are working near the battery when this occurs, it might create an ignition source that could cause the battery to explode. So, it is extremely important to remove the ground source first.

Cold Cranking Amps (CCA) is a rating used in the battery industry to define a battery' ability to start an engine in cold temperatures. The rating is the number of amps a new, fully charged battery that can deliver at 0° Fahrenheit for 30 seconds, while maintaining a voltage of at least 7.2 volts, for a 12-volt battery. The higher the CCA rating, the greater the starting power of the battery.

This is the rating used to describe the discharge load in amperes which a new, fully charged battery at 32 degrees F (0C). It can continuously deliver for 30 seconds and maintain a terminal voltage equal or greater than 1.2 volts per cell. It is sometimes referred to as marine Cranking Amps or Cranking Amps.

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.
