Solar battery testers are still relatively new in the industry; nevertheless, these items make a wonderful addition to your repair shop, garage, or even your home and car.  These devices let us know how much power is left in an accumulator and provides us with enough information about the health of the battery. 

During those horrendous winters, especially concerning our RV’s, it is vital to ensure that our car battery is still functional enough before heading out on the road. Solar battery testers work great for those of us who own a variety of machinery, namely, home solar power systems, electric cars, or any device that operates through the use of solar electricity

These testers enable us to be aware of our rechargeable batteries’ status.  Testers such as these help us know whether our batteries are in desperate need of repairs or, in many cases, replacement.  This will help owners of solar battery testers inevitably save tons of cash.   

To this effect, we have thoroughly reviewed several solar battery testers and have narrowed down the 10 best solar battery testers.

How Do Solar Battery Testers Work?

Since solar battery testers are fairly new to the market, chances are you’re unfamiliar with how they work. Here’s a quick examination of the inner workings of solar battery testers.

In truth, their operation is incredibly simple. Whilst they may come in a range of designs, with variations on function, they are all built on the same foundation. A handheld device with a small screen on which test results are displayed, and menu options are presented, is equipped with two alligator clip cables – one red, one black. These cables (you guessed it) are what you attach to the positive and negative terminals on your battery (whether in or out of a vehicle, or free-standing). Make sure you attach the red clip to the positive terminal, and the black to the negative terminal.

From here, you need simply turn on the tester, and select an option from the several available on screen. You can test a range of battery elements, from charge to voltage, cranking power, and how much life is left in the battery (level of Ohm resistance), as well as any other potential defects or issues present in the battery. On-screen instructions generally walk you through each testing process step-by-step, so that you don’t need any prior know-how to test your battery.

What makes solar battery testers so ideal for the solar industry, is that they are equipped to test even deep cycle and high-capacity batteries: the sort most commonly used in solar array storage, from residential to professional setups. The only power these testers require to operate is that provided to them by the battery. Small and portable, they can be taken wherever you go and used on just about any battery, offering test results in seconds.

Pros and Cons of Solar Battery Testers

Let’s take a brief look at some of the most fundamental advantages and disadvantages to owning a solar battery tester.


  1. Test any battery, anywhere. Thanks to the small, portable design of these solar battery testers, you can take them with you wherever you go. And since they require no power other than that provided them by the battery, they can be used whenever you like, on any type of battery: from deep cycle to small solar light batteries.
  2. Battery health. Knowing your battery’s health condition is not only prudent, it can be life-saving in an emergency. When it comes to solar arrays – systems whose energy production fluctuates a lot and often as the intensity of sunlight changes during the day – testing your battery is the only sure fire way to know that your setup is functioning efficiently and safely.
  3. Easy to use. Since most of the models we’ve listed here walk you through each step with on-screen instructions, just about anyone can use a solar battery tester, with no prior experience required.
  4. Versatile. Test a wide range of battery health elements with these chargers – not just the charge level, but the voltage, crank power and more.


  1. Expensive. For such small pieces of equipment, the price range is surprisingly high for solar battery testers. Granted, they are incredibly useful and high quality, but still, even the cheapest may be too expensive for some.

Buyers Guide

We have reviewed and chosen the 10 best products we believe will provide you with the customer satisfaction you seek when purchasing a battery tester.  Nevertheless, it is always wise to conduct a bit of your own research. After all, only you truly know what you require. 

Therefore, keep a couple of things in mind, such as the size, weight, durability, distinct battery types tested, system diagnosis, and last but not least, its user-friendliness.  Before deciding on the right product for you, one should look at some of the utmost importance factors. 

Ease of Use

You should always ask yourself if the product is easy enough to use, depending on your skill level.  Most people are not experts in the field of battery testing and analysis. Therefore be sure that the product you choose has a friendly interface and comes with easy-to-understand instructions.


Another question to ask is, what exactly will I be using this battery tester for.  Compatibility plays a major role in your decision-making since each tester has its own distinct battery types that it is associated with. Specifications to look for include the tester’s operating range in CCAs, the voltage range, and the different types of batteries (i.e., AGM Spiral Wound, Gel Cell batteries, Lead Acid Batteries, and AGM Flat Plate).


The price is an important factor that comes into question, especially when dealing with battery testers.  Luckily, there is a wide variety of options to choose from. The more hefty-priced testers come with many complicated options, but simpler ones come with wonderfully affordable prices.  The choice is yours!


Battery testers are fickle devices, as they are usually small, portable, and placed precariously in glove compartments, pockets, etc.  With this in mind, buyers should be aware of the warranty being provided by the manufacturers.  It is always good to have that peace of mind when purchasing your brand new tester.  Some in this niche market do not provide warranties, and this might influence your choice.  So, buyers, beware!

Size and Weight

As previously mentioned, these testers are a small lot built to be portable and handy. Their sizes vary from the smaller 9.6 ounces to the much larger 5-pound varieties.  This will be important for those who want a pocket device versus those that need it for professional work in a garage, etc.


There are those who have trouble reading without glasses, and having a screen to look at that is tiny and not intuitive might be a turnoff. Some testers come with LED backlight screens, while others are still using analog displays.

Final Verdict

We believe that the best overall battery tester is the SCHUMACHER SOLAR BA7 100-1200 CCA Electronic Battery and System Tester.  This great product is an overall gem compared to most of its competitors. It works with many different battery types, provides accurate readings, has a durable and portable design, and is not too highly-priced.


What is a Battery Tester?

These are devices that test the condition and performance of batteries.  Some come in a simple form and conduct simple evaluations, whilst others offer in-depth analysis and interpretations of different types of batteries and voltages.

Why Do You Need a Battery Tester?

These devices warn us if our batteries need to be replaced or charged.  In more complicated situations, these devices will give us a complete analysis of the battery in question.

How Does a Solar Battery Tester Work?

These devices measure the current that is exuding out from the battery in real-time.  The display, which is usually an LCD screen, will provide all the details of the test batteries rated in its class.

How to Choose the Best Solar Battery Tester?

It is always good to read reviews and make your own judgment as to whether they will provide you with customer satisfaction.  Some people want a fast and simple tester, while others might use it in their occupations, such as mechanics or electricians.
