Battery Facts

What is the difference between each battery?
Batteries differ in the technology inside the battery, the amount of materials used to build them, cold cranking amps (CCA) and reserve capacity (RC). As the amount of materials used in the manufacture of the battery increase (e.g. lead, acid mixture and the number of cells), so does the cost, CCA and RC.

What is an Absorbed Glass Mat (AGM) battery and why is it important?
Absorbed glass mat technology provides better cycle life and faster recharging than traditional flooded batteries. It delivers dependable starting power while also providing power to the many electronics found in today’s vehicles. Anything that plugs in or is turned on needs a battery that can handle the demand for power.

As OEMs continue to increase their standards for replacement batteries, the AGM battery helps meet those requirements for cold cranking amps, reserve capacity power, cover designs, dimensions, case hold-down and critical venting systems.


What is Reserve Capacity (RC) and why is it important?
Reserve capacity is a measurement of the number of minutes of reserve power the battery has. The number is more important now because of the drain put on batteries from today’s technology, like the car alarm, remote start, back-up camera and more.

Reserve capacity is important because it helps ensure that the power to start your vehicle is there when you need it, especially if the engine hasn’t run long enough to replace the energy used.


What is Cold Cranking Amps (CCA) and why is it important?
Cold Cranking Amps are useful in the selection of car batteries because it represents the power output used to crank a cold engine for 30 seconds. The number of cold cranking amps you need depends on your vehicle and how cold it is where you live. The colder an engine is, the more power it takes to turn the engine over to get it started. Plus, the chemical reaction in the car battery that creates electrical energy is less efficient in the cold. Simply put, if you live where it is cold, you will need more CCA.

Many people think that cold weather does more to reduce the life of a battery but the opposite is true. Heat does more damage and it shows when CCAs are needed in cold weather.


What are the top causes of battery failure?
  • Heat - The battery cells expand and contract due to changes in temperature, if the positive and negative plates touch, they cause a short and the battery fails.
  • Vibration - Exposure to heavy vibration eventually breaks down the working plates causing a short and battery failure.
