The Best Car Battery Testers

Failure to test your car battery regularly could result in a sudden power outage in the middle of nowhere. Imagine how alarming that would be. Running a test when the battery is getting low isn’t as helpful compared to checking periodically. You can throw away even a good battery just because of a careless assumption. But going to the mechanic regularly always means extra effort and hassle.

It is better to have your own battery tester for emergencies, especially when traveling or staying abroad. If you are planning to buy one now, here are the best car battery testers on the market right now:


MicTuning DC 12V Waterproof LED Digital Display Voltmeter

MicTuning DC 12V Waterproof LED Digital Display Voltmeter

First things first, cheapest dominates the list. The MicTuning LED car battery tester is waterproof and has a modern digital display. It can be used for 12 to 24 volts. It is also portable and convenient to install due to its small size and thinner design. Another great thing about this product is that it is cheaper than most but is compatible with many battery types. This car battery tester is also useful for motorcycles, boats, ATVs, UTVs, RVs, trailers, trucks and RVs.

This product also cannot be switched off. So you can easily attach it to a specific part of the ignition. This car battery tester focuses more on passive monitoring rather than manually attaching the tester to the battery when needed. Even while driving, you can see the battery status, no matter how troublesome it is. It can read voltage all the time. Some experienced product designers praise the modern design of the MicTuning battery tester.

A special feature of this car battery tester is its intense brightness. It can be very beneficial for some. However, when encountering any other bright element, especially sunlight, the screen becomes difficult to read. This product may become unresponsive, slow or inaccurate even in cold weather. If you are planning to get a battery tester for the first time, you may find MicTuning’s product difficult. It does not provide instructions for proper installation and wiring. Buying this battery tester can mean watching YouTube tutorials or asking Google.

Cartman 12V LED Car Battery & Alternator Tester

Cartman 12V LED car battery and alternator tester

Another cheaper option, the Cartman car battery tester also has an LED indicator. Although it is only suitable for 12 volt batteries, it is still a quality and durable product compared to most others. Its characteristics can be very similar to some well-known brands. However, this remains one of the cheapest.

Cartman’s product comes with excellent quality clamps. Compared to other brands in the same price range, it is much more convenient since there are no needle-like containers. Coiled cables, unlike this battery tester, tend to deteriorate easily. This battery tester also reads quickly in seconds after touching the terminals on the battery terminals. Checking your car battery once a month would be a breeze. Thankfully, this tester strives for simplicity.

You can also use this product when charging the car battery. This procedure will help you avoid overcharging. This battery tester is a good alternative to a multimeter. Its portability also makes it perfect for emergencies. It is not recommended for shops, but can be very useful as a supplement to the tool bag when travelling.

Unfortunately, the size of this product is very small for some best car batteries. More specifically, its wires may be too short to reach the connectors. Still, this car battery tester is one of the most durable.

Other products to consider

Here are other examples of the best car battery testers that are much more expensive but may be more suitable for professional use:


Clore Automotive Solar Cold Cranking Amps LED Electronic Battery Tester

Clore Automotive Solar Cold Cranking Amps LED Electronic Battery Tester

This is the most expensive here. The Clore Automotive Car Battery Tester can test 12 volt batteries from 100 to 1200 cold cranking amps (CCA) with an operating range of 7 to 15 volts. It is also compatible with different types of batteries such as deep cycle, spiral, gel, AGM and conventional batteries. It can also be user-friendly as the gadget itself guides the user through the process. Unlike MicTuning, this product’s LED display can be adjusted to be bright or dim. This makes it easy to read.

The construction of the gadget is well thought out. Its size is also portable. This car battery tester can remember the latest information such as battery type, German industrial standard or simply DIN, and test grade CCA. Some power engineers recommend this product. Some brands actually offer similar products to this one, but this one from Clore Automotive is cheaper. For the price, however, there were still more longevity or durability issues than some cheaper options.

Schumacher battery load tester

Schumacher battery load tester

This car battery tester from Schumacher can carry out a 100 ampere load test for 12 volt batteries. On the other hand, it delivers 50 amps for 6 volts. Both volts can be tested up to 1,000 CCA. Unlike previous products, this item is recommended in stores.

However, due to its limitations, it would last longer in smaller stores. In particular, it is not a computerized resistance circuit tester, but a more advanced and suitable tool for larger companies. Despite the limited capacity, it is still recognized by some professional technicians.

Like Clore Automotive’s product, Schumacher’s car battery tester has a tendency to last no more than a year. Its cables can quickly become detached.

INNOVA battery and charging system monitor

INNOVA battery and charging system monitor

The car battery tester from INNOVA can be easily connected to the vehicle’s socket. It is designed for negative ground systems of 12 volts. The LCD display shows a bar graph to determine the battery level. Meanwhile, the LEDs with different color codes indicate the charging status. Reading data is easy at different angles because the head of the device rotates.

This product is very similar to MicTuning car battery monitor. You can also plug this in at any time while driving. Like the first choice of our best car battery testers, INNOVA also relies on passive, constant monitoring. Some buyers are happy to testify that this product can last for years. However, many were disappointed due to allegedly inferior construction.

How to choose the right car battery tester

The downfall of all battery testers is the inaccurate reading. We need to know the factors that lead us to avoid erroneous data.

100A step capacity

One of the most common mistakes made by a car owner is assuming that all car battery testers have the same test mode. In fact, battery testers have different test ranges. What we look for in a good battery tester is the ability to set the meter for an additional 100 amps. For example, you can switch from 400 CCA to 500 CCA. This contributes to more accurate readings in the future.

Durability

Who wants a poorly designed product? We should prefer a car battery tester with a sturdy metal structure for intense durability. The handle must be well insulated. Also, the tester needs terminals that are measured just right. We don’t want bulky brackets and dainty little ones. For accurate data, the carbon stack must also form the load resistance.

Simple monitor

For the sake of simplicity, we need a car battery tester with a clearly printed scale. The product’s lens must not distort the display when viewed from different angles. Inaccurate readings can sometimes be caused due to refraction of the lens over the meter pointer.

It is difficult to review every product of the best car battery testers to make the best choice. Why? Everyone just can’t please everyone. Every battery tester has encountered dissatisfied customers due to inaccurate readings. However, if you follow our tips for choosing the right product, you can avoid this inconvenience.
