Best Battery Testers: ZTS MBT-1 Made in the USA

Choosing the best battery tester isn’t as simple as it sounds. With numerous models on the market, it can become a little overwhelming. As this article will explain, all battery testers are not the same. Believe me, you’re going to be surprised.

Before I let you in on the truth behind battery testers, consider this. Batteries are so common in our daily lives that most of the time we forget we are using them.

Call them what you will, flat battery, discharged battery, run-down battery, completely dead battery, whatever – they look the same when they’re fully charged as when they’re dead.

That’s the frustrating thing!

This clever gadget will take away all those frustrations.

ZTS MBT-1 Multi Battery Tester Review

ZTS is a US company that has specialized in electronic testing equipment since its creation in 1976.

The MBT-1 is probably the most versatile battery checker on the market.

The MBT-1 has been updated for 2020, and can now test a wider range of lithium button type cells.

this is the best battery tester

What Cells Can It Test?

Naturally, you would expect this machine to test alkaline, NiMH, and NiCd rechargeables—and of course, it does. However, it’s the ability to test other formats as well that initially make this unit stand out. It’s almost a universal battery tester.

Is This The Best Battery Tester For Small Batteries?

Barring combined cells (as in power tools) and the enormous 6-volt batteries found in older 35mm cameras—there are few batteries it cannot test.

It can test small button and coin cells such as the “LR44” and “3v lithium CR2032”.

Additionally, the more substantial 18650 batteries are catered for.

I have provided a complete list of battery compatibilities in the specifications section.

Is This The Best 18650 Battery Tester?

It has to be the most reliable tool for analyzing your 18650 batteries and tells you the battery condition. You can find the best 18650 battery charger here.

Is This The Best Tester For Rechargeable Batteries?

Absolutely! This will certainly test your rechargeables, and it’s also very portable.

Is This The Best Tester For Home Use?

Yes, we’re sure that currently there is no better alternative. It will test a large variety of dry cells, it’s a button cell/coin cell battery tester, a 3-volt battery tester, it will test CR3032, CR2, and CR123 batteries. It will also test your 18650 flashlight batteries.

It will test D cells as well as AA and AAA cells, both alkaline and Lithium. It is also a 9v battery tester.

How Does It Test Batteries?

The MBT-1 uses the pulse load system. Therefore, it is perfect if you want to know the exact status of your battery, not just the voltage.

There is no requirement for the user to manually select settings. The unit automatically recognizes the battery type and performs the correct pulse test.

After approximately two to three seconds (dependent on battery) the results are given. The unit automatically cuts off after the test to prevent unwanted drain.

ZTS Mini-MBT Multi Battery Testers Review

It would be hard to improve on the ZTS MBT-1 reviewed above. The Mini version may not be an improvement, but it does take it in a slightly different direction.

​This is possibly one of the best battery testers for small batteries out there.

What Exactly Can It Test?

Please check below in the specifications for the exact battery sizes. But, in short, it can test nickel rechargeable batteries, standard and 9-volt alkalines, 18650s and 3-volt coins.

This will cover the majority of batteries that most people have in their household, this machine can test over 15 different types.

How Does the Mini-MBT Perform The Test?

As a good load tester, it uses a pulse-load test. It’s good to see that, despite being scaled-down, this feature has not been omitted.

Ease of Use

Like the MBT-1, using the mini version is simple. Place the positive end of the battery on the unit contact and a probe on the other, that’s it!

The contacts are still large and therefore comfortable to keep a battery in contact at all times. Even people with larger hands will find that operation is simple, despite the transportable size.

Once the microprocessor has powered into life and the two-second test is complete, the LED flashes. This indicates the remaining capacity in the cell—20, 40, 60, or 80 percent.

Size, Weight, and Build

If provenance is important to you, this tester may appeal. It is both manufactured and supplied from its US base in Ohio. They’ve been making quality battery analyzers for years.

However, it’s the size, weight, and build of this unit that makes it most appealing. Weighing just 3 ounces and measuring 4 inches by 2.5 inches, it can easily be placed in pockets or a drawer. That’s lighter and smaller than many smartphones.

This small unit is still sturdy and well-protected. The edges are rubberized to protect from bumps and scrapes. Furthermore, the “flat-face” design and lack of perspex, glass, or buttons, means there is little to be damaged or broken.

A textured edge allows the tester to be gripped firmly, even when being used with oily hands. This reduces the chance of accidental droppage.

What I Like About the ZTS Mini-MBT Small Battery Tester

  • Small and light—easily transportable and comfortable in the pocket.
  • Tests the most common cell sizes found in devices—and more.
  • This tester is made in the USA.
  • Large contacts and text are not compromised due to the overall size.
  • Pulse-load test—not voltage.
  • Probe and cable slot neatly into the tester’s side.
  • Sturdy with rubber-treaded edges.

What I Don’t Like About It

  • Lacks testing ability for some cells—check specifications below for detail.
  • Carrying case involves an extra purchase, which can be found here.

Final Thoughts on the Mini-MBT Multi Tester

Although small, this tester is one of the most useful in the portable category. Compatible with a wide range of common, and some less common, batteries including the popular 18650, makes it ideal for the home user.

Size has not compromised important features, such as pulse load testing, terminal contact area, and typeface. Rugged, tidy, and easily held in the hands, it will still stand up to frequent use.

The Bottom Line

As I have illustrated, having a battery analyzer is a worthwhile investment. It can save you money, reduce aggravation, prolong battery life and have a positive effect on the environment.

However, it is important to stress that there are many budget-friendly testers on the market that simply do not perform. In many cases they often don’t provide accurate results, only perform voltage tests.

They can actually drain the cell being tested. That’s why it is important to select the best battery tester.

In my opinion, the ZTS MBT-1 is the top battery tester on the market. With its pulse load testing feature, wide-ranging versatility in battery types and incredible ease of use— it’s hard to beat.

Even NASA uses these testers, so they definitely know how to put together a quality, easy to use battery tester!

That being said, I cannot finish without praising the Mini tester. For a smaller battery tester, it packs more useful elements than many other manufacturers’ full-size versions. Making it ideal for the serious domestic battery tester/ home user.

But, the cream of the crop of battery testers has to be the MBT-1.

I really hope that this article has helped you in making your choice. Choosing a quality battery tester will give you years of reliable use, and remove the guesswork when replacing cells.
