KNOWLEDGE IS POWER

battery icon

Most car batteries last 3-5 years. If your battery is 4 years old or older, it is at higher risk for failure. One out of every four vehicles on the road will likely need a new battery this year.

Cold cranking amps measures your battery's ability to start an engine. The specific measurement is the amount of amps delivered over 30 seconds at 0°F. High cold cranking amps give you a rough indication of a battery's starting power in difficult conditions.

battery life indicator icon

Reserve capacity refers to the amount of time (in minutes) a battery can provide power before being fully discharged. High reserve capacity is especially important for modern vehicles with accessories like heated seats and infotainment systems.
