Cons

  • ​Some units ship without instructions



#3. ​​Neoteck PW020

Neoteck PW020

Next up, we have the Neoteck PW020. This model may look rather basic at first blush, but it is actually packed with multiple functions that operate at the same time. For example, when you attach this model’s colour-coded alligator clamps to your battery’s terminals, the Neoteck PW020 will instantly run a check of your battery’s state as well as your alternator’s health. Using the information readouts provided by this model’s 6 differentiated LED indicators, you can remain proactive when it comes to maintaining these two critical vehicle components.

Those aforementioned alligator clamps are worth a second mention. That’s because this model’s alligator clamps are insulated right out of the box. This allows them to safely operate and remain productive far longer than the clamps used by their competitors. Be sure to keep in mind that these clamps are a little smaller than average, so they may not fit larger battery terminals.

Pros

  • ​Checks battery status and alternator status at the same time
  • 6 LED lights indicate statuses, including if a fault is detected
  • Alligator clamps are insulated, allowing them to remain safe and productive through many uses
  • Clamps are colour-coded to match battery terminals

Cons

  • ​​Clamps only fit flat terminals well
  • Instructions could be more clearly written



#4. ​​MOTOPOWER MP0514D

MOTOPOWER MP0514D

Like the #2 pick in our collection, the MOTOPOWER MP0514D utilizes a fantastic microprocessor that allows it to return hyper-accurate results in mere seconds. In fact, internally, this model is noticeably similar, even down to its inclusion of reverse hookups and over-voltage protections. Interacting with your test results on this unit isn’t a major hassle either due to the crisp contrast on its lighted digital display.

However, the MOTOPOWER MP0514D does have one important feature that allows it to standout – literally. Specifically, this model comes in a bright orange case that provides it with plenty of visibility while you fish it out from your glove box. Along the same lines, you shouldn’t have any trouble attaching this model’s 30 amp clamps, which are just a bit larger than previous versions.

Pros

  • ​​30 amp alligator clamps compatible with most 12 volt battery terminals

​Automotive ​Battery Testers Buying Considerations

Know Your Skill Level

Before you purchase a new car battery tester, you should self-evaluate your own skills when it comes to vehicle maintenance. While most car battery testers are fairly safe to operate, they do come with the slight risk of electrocution due to their direct interface with your car’s battery terminals. If you don’t feel confident about your skills in this department, you may choose to seek out a professional battery evaluation from a trained mechanic instead.

Use a Model Compatible with your Car’s Battery

As a rule, most modern car battery testers work with the 12 volt batteries that are installed into most foreign and domestic vehicles today. However, some more compact models make use of a 6 volt battery, which in turn requires you to obtain a tester that is compatible with small cell types. While some specialized models can test both battery types with the same clamps, you may also need to pick up a devoted 6 volt car battery tester to keep in your glove box.

The Final Word

​While you could just hope that your battery will remain charged enough to get you ​around in your car, you could also know your car battery’s status with certainty by using a car battery tester regularly. ​Our list of the best car battery testers ​is designed to help you find a ​testing device for your motor that’s right for your budget and battery type, ​ensuring that you're on top of your battery condition and status.
