I have a ’79 Ford, that I store in the winters. This device is a great way for me to check the status of the battery, and the alternator, while I keep it in storage. For this price, it’s a great deal. It lets me know if the battery needs charging, and it saved me from buying a new alternator when the voltage regulator failed. Not a complex device, but just enough to be useful.


I frequently test car batteries at our small dealership prior to charging them with a battery charger. I was looking for a cheap and easy method to quickly test battery charge levels and potential alternator issues. The Schumacher battery charger I have has a test/charge meter but it is a complete joke. I’ve been using this little tester for a few days now and it works great. I’ve found it to be fairly accurate for a general reading.

Try it and it works right out of the box. Try it on a Jeep Wrangler, Toyota Tacoma, Nissan Versa, Honda Accord and some solar power batteries. It’s really small and compact. Had read some reviews and yes the wires are to short, wish they were longer but I can live with it.


This unit works very nicely and is 90% accurate according to what I’ve compared to the auto part stores when they’ve checked my battery and alternator.

I’ve used this on multiple vehicles and it’s been accurate every time. Two times it said a battery was toast and after replacing it worked great. Another battery tested and I was told to recharge and try again and after the recharge it said the battery was still good.

How to Choose the Best Car Battery Tester?

There are a range of features that you might see in high-end models, but for ideal use, you need to ensure five key features which are as follow – 


Several types of battery tester systems are available in the market, and you can choose between scalar, vector, and Spectro. Each one has different features, so you have to understand the need before finalizing the purchase. On the other hand, you should go with a digital car battery tester because they provide better detail about working.

Built Quality

It is easy to break a battery tester in a shop because there are so many heavy tools and equipment. To never take any charge, always go after the battery tester, which provides higher build quality and is made up of sturdy plastic. Even some battery tester comes with sturdy cases to prevent them from dropping them.

Battery Compatibility

One of the most important functionalities is battery compatibility, and you should know how much power it can check. Most of the batteries for cars require 12v power, so your tester should be able to check this much voltage. If you have SUVs or light trucks, then you might need a different kind of battery tester.


You can find that few battery testers only help you check out the charge status only, and they can help you know about whether the battery is faulty or not. But, if you want better functionality, then you can alter for better products with more features. You can consider the need and type of batteries you will be checking on a daily basis.


Usually, the cable offered with the battery tester is small, but if you are checking the truck on vans batteries, then you might need a long cable. So, it depends upon the car you have.


  • How do you test if a battery is good or not?
  • Can a battery be bad but test good?
  • How does a 12-volt battery tester work?
  • What does a battery tester test?
  • How do I know when my car battery needs replacing?

The Final Verdict

Car battery testers are compact and lightweight, so they are easy to keep inside your car. To avoid facing any problem, you can check car batteries once a week to ensure effective working. If you live in a cold region, then having a battery tester is a must. The reason is that batteries stop working suddenly due to lower voltage, and keeping track of battery health is an essential factor.
