5 Best Solar Battery Testers Reviews For 2022

Cold weather is always hard on batteries and the car engine does not start when the oil gets thick. Likewise, in hot weather, water reduces in the battery electrolytes and it stops producing power. You can overcome these issues through a solar battery tester. Such a device can display readings on its screen and inform you if the battery is dead or low.

The battery has to be active for the power backup of the vehicle’s electronic components. The charging system produces more power when the engine is working. But, when the engine is idle, radio, lights, heaters, and other accessories put extra load on the solar system getting more power from the battery, eventually, it gets slow or dead.

You can prevent overload by testing a battery because the loss of power can create different issues. You can connect a solar battery tester to a vehicle’s battery through a cable. It can check the entire charging system, cranking, and load, helping you monitor your battery and take action if need to. The testing device can keep the battery running, eventually, the car, truck, boat, or whatever vehicle you have will stay running.

Buying Guide

Batteries are expensive items, especially vehicle batteries, so they need care in terms of maintenance and function. A few factors need your attention while purchasing a solar battery tester.

LCD Display

The display is important in the case of a testing device so you can monitor your battery performance. The screen should have enough size and light to help users read information.

The digital readings are easy to understand so choose such a battery tester. Some cheap devices don’t display clearly and you misinterpret the results.

Likewise, the font should be readable because it’s hard to read a very small or complex font style. The above testers have backlit screens which are ideal for any lighting condition.

Easy To Handle

The tester must be easy to handle and portable. However, the weight, and size of the tester determine its portability. Likewise, the cable length should be moderate, especially if you can’t hold a long wire. Most new testing devices are compact and light so you can carry them easily.

However, make sure the lightweight testers are also strong, or they will not work after a few times of use.

How Many Parameters You Require

While buying the solar battery tester BA7, or any other model, you must ensure its parameters. If you need a simple tester for voltage, just focus on it. But, you can evaluate more functions like the above models. The most advanced testing devices are complex as they can analyze the complete functions of the battery to produce more results.

A Versatile Tester

Some testers can scan only a specific battery whereas some are versatile and can test various batteries. But, it also depends on the solar power system you are using. Generally, a lithium battery is common in this case because of its reliability, life, and compact size, but it is costly.

Homeowners often prefer lead-acid batteries so they can store more power to deal with the power shortage. These batteries are not long-lasting but they are cheap compared to lithium batteries. All you need is to buy a tester compatible with the solar power system you have.

The above testers go well with several kinds of batteries, so overall they can cost you less as you can use them for other batteries as well.


You need a solar power system for clean energy, but is your solar battery always functioning?  A solar battery tester can protect you from a lot of hassle and helps you measure the battery capacity and the entire system. The test results show if you need a new battery or have to maintain the old one.

The battery testing devices don’t need internal batteries as you can operate them through the battery you are testing. The above battery testers are compatible with several batteries, besides they are reliable. You can check your solar power system easily without getting expensive professional help.

If you don’t have a tester, your solar power product can stop anytime or get slow due to the battery malfunction. Our reviews reveal that advanced testers can display results within a few seconds. Wouldn’t it be annoying for you during Covid when your solar power system does not work and you have to find a technician to fix the issue? Better have solar battery testers and save your battery.

How Do You Use A Solar Battery Tester?

By using the solar battery tester, you can measure the current that the battery produces. The LCD displays the results that help to evaluate the battery performance, as well as its entire system.

You have to connect the wire with the battery terminal to get the readings. These cables come with testers. You can also get to know your new testing device through its manual. Some testers show codes to manage the results of various functions, and you must understand them.

Are Battery Testers Accurate?

No matter how good a solar battery tester you use, the battery will show the exact voltage only if it’s under load. So, without load, the readings will not be correct. Like, if you cannot properly connect a tester cable to a battery terminal, it will not give a correct reading.

You need a special tester for each battery to get the correct results. Such as not all testers can scan a lithium battery. Rechargeable batteries can also produce incorrect readings even if their charging is around 50 %.

High-tech battery testers are so developed that they can test a battery under load with a correct analysis. Multi-meters are also available but they only detect the voltage.

However, a battery tester helps you find if the battery is dead or working. People often mix up the old and new batteries while replacing them, but the battery tester can help them find which battery is new.

At the same time, the cable should be well connected with the battery or the tester will not show the correct current. That means you must know how to use a tester including a solar battery tester BA5 to scan your battery.
