AutoZone uses advanced technology that can work on any type or size of automotive batteries, whether it be sealed lead-acid (SLA) or wet cell. What does AutoZone battery test check?ĪutoZone battery test is meant to check for the condition of your car’s batteries. This methodology will always yield a battery that will last a few months longer than its “life expectancy” prior to the replacement. Most people make calculated assumptions based on prior usage patterns and simply replace their old “dead” battery with a newer model before using up its current charge capacity entirely.
Most batteries have indicators built into them that can help predict when they will need to be replaced – but those indicators are course and only work on dead batteries.Īs an example, lithium-ion batteries lose their charge at about five percent per month until eventually they cannot be recharged at all. If a charger/tester says that there is still life left in the battery, then most likely, it’s time for the owner to invest in a replacement. The primary purpose of a battery tester is to determine whether a battery needs to be replaced.
How accurate are battery testers?Ī battery tester provides you with some measure of whether the battery has enough voltage to power your device for an acceptable period of time. Even if it did test them, the results would be inaccurate. The AutoZone Battery Test will not work on some special batteries such as Lithium-Ion or Nickel-Metal Hydride used in electric cars because they have a different voltage than normal lead-acid ones (around 48V, instead of 12). The test takes about 60-90 seconds and is very straightforward. If you’re confused about how does AutoZone test batteries works, the AutoZone Battery Test works by applying a load to the battery while measuring the voltage drop across it once loaded, which gives an accurate estimation of its state of health. Its accuracy is more than 99% when batteries are in good condition and not too old (less than three years). The AutoZone Battery Test is 99% accurate in testing traditional 12Volt batteries, including wet cell deep cycle/ starting, AGM, and gel cell. There are many factors that may affect the accuracy of a battery tester, such as age and condition of batteries or type (some testers will not work on lead-acid). So the next time you’ll try the AutoZone battery tester, you’re sure to have accurate car battery test results. There are many different companies that offer this service, and most of them have pretty good results, but the best one would be AutoZone. It is important for battery testing to be accurate as you do not want to put a new battery in your car if it is not necessary. With a better selection than many other retailers and more than 60 years of experience since opening the first store in 1984, I think you’ll find a good resource for everything from the basic to the advanced from Autozone.
