What to Consider When Choosing the Best Battery Tester

Staying on top of battery health can ensure that power equipment, vehicle, or even video-game controllers are working properly. Plus, these devices are more versatile than their name implies, as they can do more than just test voltage. The following sections point out the most critical factors to consider when choosing the best battery tester.

Types of Battery Testers

The two main types of battery testers, digital and analog, differ in the way they deliver information to the user.

  • Digital battery testers feature LCD displays that provide clear, accurate, easy-to-understand readings. Typically, users can switch between settings for static, cranking, and charging tests with a button. While digital models don’t boast new technology, they’re much more advanced than their analog counterparts.
  • Analog battery testers can be harder to read than digital models. They have a needle that rises and falls across a printed gauge, indicating the power level in the battery. The gauge is fairly small and has hash marks as well as numbers, so the reading may be less precise than with a digital tester. Also keep in mind that some analog testers do not have their own on-board batteries, so if the battery being tested is dead, none of the features will work.

Battery Type 

It’s important to know what kind of battery you’ll be testing, since not all testers are compatible with every kind of battery. Battery types include wet or flood cell, cylindrical, AGM (absorbed glass mat), gel cell, spiral wound, deep cycle, and more—designations that refer to the chemical makeup or construction of the battery.

Also, batteries vary in the voltage they produce. Smaller batteries, such as AA, AAA, C, and D, produce only 1.5 volts. These batteries don’t produce enough electrical signal for some battery testers, so testers designed for lower voltage are necessary. The units that can test these lower-voltage batteries typically don’t require leads, which are electrical contact points on the end of a wire.

Batteries found in older lawn equipment, small power tools, and some older motorcycles produce 6 volts, while larger vehicles such as cars and trucks use 12 volts. Both of these battery types require leads for testing.

Ease of Use 

Most battery testers are straightforward tools, but overly large, clunky models can be tedious to set up. Also, models with small gauges or tiny digital readouts can be difficult to read. The best battery tester will have a large gauge that’s easy to read quickly and accurately. A quality digital model will also feature straightforward buttons and control pads.

For smaller batteries, one-hand use can make testing a much faster process. For larger batteries, clip-on leads can make a huge difference, especially when going for accurate readings during cranking.

Connector Leads 

The best battery testers designed for larger batteries require leads, the electrical contact points on the end of a wire. One lead goes to the negative side of the battery, while the other goes to the positive side. As the energy from the battery passes through the leads, it registers a reading on the tester.

The leads on battery testers typically come in two types: points and clips. Points will do the trick, but clips attach the leads securely to the battery so the user can focus on the readings. This can be a big help, particularly while testing batteries in larger vehicles with complex electrical systems.

Types of Readings and Modes

Vehicle battery testers differ from multimeters in that they take different types of readings. They can take static readings when the battery isn’t connected to the car, load readings when it is connected, and readings during cranking and charging cycles.

With most digital models, users can hook these battery testers to the terminals, set it to the correct setting, place it on a surface, and then board the vehicle and crank the ignition. The battery will take all the readings and display them when the user gets out to review them.

Many testers also have settings for “in car” and “out of car” readings, which can be helpful for determining parasitic draw (when the vehicle drains the battery, even when it’s off).


While testing the batteries in larger vehicles, users must often place the unit down on the vehicle. Whether it’s on top of the battery, on the edge of the fender, or on top of an air cleaner, putting the tester down allows the user to manipulate the leads with both hands. If the tester doesn’t have a grippy surface, it can slide off and become damaged. So a rubber anti-slip surface is helpful when testing vehicles. Some models feature rubber covers, while others might have a strip of rubber across the back.


Still have a few more questions surging through your mind? Check out the answers to some common queries about battery testers.

Q. How accurate are battery load testers? 

Battery testers are relatively simple tools, so accuracy is rarely an issue. Digital models are highly accurate, while the gauges in an analog tester might be harder to read with the same pinpoint accuracy.

Q. How do I test a battery to see if it’s good?

To test a battery, either place it in the appropriate slot in the tester or press the leads to the terminals of the battery. Analog models should provide a reading right away. Digital models might have a few menu prompts to follow before getting a reading.

Q. How long will my battery tester last? 

Battery testers are relatively simple tools, so it’s not unreasonable to expect 10 years of service from a quality model. Do keep in mind that most testers run on a battery, which typically needs to be changed once each year.
