Ed’s Question:
What is the effect on a car battery's expected life in Arizona's heat? I have heard that batteries do not last long. Are there any other maintenance issues because of the severe summer heat?

Auto Advice:
The average life expectancy of a car battery in Arizona is 22 months. Regardless of the length of the warranty on your battery, if it has been in your car for more than 22 months in Arizona, you are running on borrowed time. Most car battery failures in Arizona happen without warning. You don’t get the slow cranking, dim lights, or other warning signs that you may notice in moderate or cold-weather states. The battery just dies in most cases. The only way you can know the condition of your car’s battery is to have it tested. If your battery is over 22 months old, you should consider having it tested the next time your car is in the shop for routine maintenance.

As for other maintenance issues due to Arizona’s severe summer heat, you will notice that you go through rubber parts more quickly here in the desert. Things like wiper blades, motor mounts, belts, hoses, and tires just don’t last as long in the severe heat and extreme dry conditions. In addition to the heat, the dust tends to take a toll on air and cabin filters. Both should be replaced annually for maximum benefit.

The benefits that we humans come to Arizona to enjoy — warmth and sunny days — can be hard on our cars and trucks. However, if we acknowledge this trade-off and are prepared to perform the added maintenance, there shouldn’t be a problem.
