Car Battery Testers FAQs

Because there is such a wide variety of auto-battery testers available at a broad range of prices, knowing which one will best suit your needs can be a challenge. That challenge tends to raise some common questions to which we’ve provided the answers.

Why do you need a battery tester?

If your car won’t start or is not running properly one of the many possible causes could be related to the performance of your battery. However, it is not the only possible cause. With a battery tester, you can easily determine whether you can eliminate battery performance from among those causes or focus on it as the solution.

How do battery testers work?

In the simplest terms, battery testers measure the strength of the current available from your battery. The result of that measurement is displayed in amperes or amps, which is the flow of electromagnetic force between two conductors. Various testers also analyze other aspects of your battery, which we will discuss below, but this is the simplest definition of the function of a battery tester.

What are the various types of battery testers?

Various battery testers use different approaches to testing, analyze different aspects of a battery and provide different results. There are basically three types of battery testers or acceptable measurement techniques, including:

• Scalar. This type of tester takes a single reading and compares it to a single standard of reference for determining battery capacity. It is pretty basic, but is often all that you need when it comes to figuring out why your car won’t start.
• Vector. A less common type, due to its complexity, a vector monitoring system applies multiple frequencies and currents to a battery in order to measure their response rates at various vector points. This type of tester allows the user to pinpoint stress points in the current. This is a bit more high performance testing than most mechanics tend to go, but it is used for car battery analysis.
• Spectro. Most auto-battery testers do not use this type of technology. Spectro type testers scan batteries with a particular frequency that only works with lithium type batteries. So, although you might want to test the battery on your mobile phone or laptop with this type of tester, it is essentially useless for car battery testing.

The technology used in each of these types allow for varying degrees of accuracy, varying levels of analysis, varying results, and can affect the overall price of the tester as well.

Which is the best type of auto battery tester?

For the most common applications, the best type of auto battery tester is going to be a scalar type. However, those who work with high-performance autos might find that a scalar type tester does not provide enough information, which is a problem solved by a vector type tester.



Car Battery Testers Mini-Buyer’s Guide

An auto-battery tester can be something pretty simple, similar to a voltage meter in letting you know whether or not your battery is charged, or it can provide you with more analysis. How you intend to use your battery tester and what information you expect it to provide will determine which model best serves your needs. There are some basic features, which provide you with a standard of comparison between various models.


Keep in mind that an auto-battery tester is used in a place where steel and concrete are also present. That means that the quality of construction and the materials used to make the tester need to be pretty durable. In addition, you will want the tester to be well-insulated so that you can use it without receiving a jolt.

Load and Capacity Testing

Because not all batteries are the same, even if they are labeled the same, the ability to test the load and capacity of a battery is an essential element in understanding its performance. A good 12V battery tester will allow you to select a testing range for cold cranking amps or other various load and capacity. With a higher quality tester comes greater precision in the various increments of adjustment and a wider variety of loads and capacities that you can test.

Supported Battery Types

There are a number of different battery types used in automobiles. Each one will test just a little bit differently, which makes it necessary to have a tester that is compatible with the battery type in your vehicle. Here are the main battery types:

• Wet-cell, Acid or Flooded. The most common type of auto-battery, which comes in either maintenance-free or serviceable options (that means you can fill it up with electrolytes).
• Gel. Generally speaking, this is a type of wet-cell battery, which is maintenance free and uses gel for conduction rather than acid.
• AGM. Absorbed glass matt, which is what AGM stands for, batteries suspend the batteries electrolytes closer to the batteries plates to provide greater performance and overall longevity.
• Spiral. This is a type of AGM battery with a six-pack set of spiral cells with higher power and cycling capacities and improved vibration resistance.

Easy to Use and Read

A battery tester is not worth the money and time you put into it if it is hard to use or difficult to read. Even a simple analogue-style tester that is easy to use and read is better than a clumsy, unreadable digital model with all the bells and whistles. Here is what to look for:

• Clear graphics with a good color and brightness contrast between background and graphics.
• Results that are easy to understand.
• On-screen and/or off-screen instructions that are easy to read and follow.
• Streamlined design and construction that isn’t too bulky.
• Leads that are long enough to reach your battery from wherever you place your tester.

Added Features

The features we just mentioned are the most basic ones to consider when comparing battery tester models. However, certain features add to the value of an auto-battery tester, and they can also add to the price. When it comes to these added features, each individual user will have to determine which ones are worth that extra bit of cash you will have to shell out. Here are some of the added features that come on some battery tester models:

• Data export for extended analysis.
• Connectivity options.
• Printing function.
• Ability to test a wider variety of battery voltages.


Whether you just need to know if your battery is shot and needs to be replaced or more in depth analysis of your car battery’s performance, an auto-battery tester is a good tool to have in your shop. Having taken into consideration the various features available and having compared a variety of car battery tester models, you should be better informed to make a quality selection of the tester that best suits your needs.
