PICKING THE RIGHT BATTERY
The best battery for your vehicle is the one that meets or exceeds the original equipment installed by the manufacturer. Talk with an AutoZoner or enter your vehicle on AutoZone.com for recommendations. Even if a Duralast battery is recommended, upgrading to a Duralast Gold or Duralast Platinum battery can provide the peace of mind that comes with a longer warranty and additional power. These higher-powered options are well-equipped for running accessories like heated seats and infotainment systems that are common in modern vehicles.
Talk to an AutoZoner at your local AutoZone about your vehicle and your needs to help guide you through the battery selection process, or enter your vehicle on AutoZone.com for recommendations that fit your vehicle. AutoZone carries Duralast, Duralast Gold and Duralast Platinum Batteries – each with their own design, warranties and power specifications.
DURALAST – 2 YEAR WARRANTY
Proven Tough Duralast Batteries come with a 2 year warranty and provide ample power and cold cranking amps for most situations. Duralast batteries are built for vibration resistance, longer life, more power and quick starts – even in extreme weather conditions.
DURALAST GOLD – 3 YEAR WARRANTY
Duralast Gold Batteries are heavier, equipped with more lead plates for greater vibration resistance and more power. These batteries are ideal for vehicles with high power demands like heated seats or infotainment systems.
DURALAST PLATINUM – 3 YEAR WARRANTY
Duralast Platinum Batteries power more with flat-plate Absorbent Glass Mat (AGM) technology. Duralast Platinum batteries are sealed and spill-proof, extremely vibration resistant, mount in almost any position and carry two-times the deep cycle capacity of a Duralast Gold Battery. Duralast Platinum Batteries are the best choice for starting your vehicle and maintaining all your power demands. Comes with a 3 year full replacement warranty.
MEASURING BATTERY POWER
Three traditional measures of battery power are listed right on the label.
Cranking Amps (CA) – Indicates the number of amps a new, fully charged battery can deliver continuously at 32° F for 30 seconds while maintaining a voltage of at least 7.2 volts.
Cold Cranking Amps (CCA) – Refers to how much power the battery can generate while “cold,” specifically when starting the engine. This measures the battery’s ability to go from not in use at all to providing a lot of power quickly. Modern vehicles start very quickly so cold cranking amps are not as important on later-model vehicles.
Reserve Capacity (RC) – Shows the number of minutes at 80° F a battery can be discharged at 25 amps and maintain at least 10.5 volts for a 12 volt battery.
WHAT DOES THAT MEAN?
Batteries have a lot of measures for their performance, but ultimately your vehicle, how you operate it and the warranty length should have the biggest influence on your decision. Live in a moderate climate and don’t run a lot of accessories? Proven Tough Duralast may be the way to go.
Used to harsh winters or blistering summers and spend a lot of time blasting the A/C or powering up heated seats? Probably want to upgrade to Duralast Gold or Duralast Platinum. When you’re ready to get your next battery, stop by your local AutoZone or visit AutoZone.com for specific recommendations.
