Best Car Battery Tester

Category: Engine & Performance

Last Updated on

There is not one person in the entire world that enjoys climbing into their vehicle and attempting to start their vehicle, only to find that the engine will not crank, the lights will not come on and you must have a dead battery. That terrible clicking noise of the car not turning over is all too familiar and all too scary. This is such a pesky fiasco that can ruin anyone’s day and it happens for all sorts of reasons. Maybe you or someone else accidentally left the car’s interior lights or headlights on. Possibly, the car hasn’t been started for a long period of time. Maybe the battery is just old or was not properly maintained. Batteries sometimes need their terminals cleaned out. Sometimes, in cold weather, the battery can just freeze. Unless you are an auto mechanic, to prevent such a hindrance, you should be checking your car’s battery power every so often.

Let’s avoid having to jump start the car, with the probability of that battery just dying over and over on you until you replace it. Wouldn’t it be nice to just be able to have some sort of premonition before that battery croaks? Car battery testers can help. Choosing the best car battery tester is an essential part of maintaining your vehicle. To ensure you get the best bang for your buck for a quality and affordable tester, here’s a look at some of the top-rated brands.

Top Car Battery Testers

Your vehicle’s battery is a key component to the car and is also vulnerable. At any time, it can just go out, turn off and stop working. Then what? It’d be nice if your vehicle had the ability to diagnose the vehicle battery issue itself, but it does not. A car battery tester is a basic device that you can use to simply check up on the status of your battery on your own. This is guaranteed to save you so much in mechanic and car dealer fees. You will be able to know when to replace your battery before it dies to avoid the surprise of it dying on its own. This is a small investment to save you frustration and time!

Essentially, a functioning vehicle battery should be operating at 12.6 volts or more and when the engine on your car is running, it should increase to 14 volts. Battery testers work by connecting a conductive lead between the tester and the battery.

It’s time to say goodbye to those jumper cables. Picking out the right battery tester for you can be a bit complicated. Some are expensive and some aren’t. The features and abilities vary across the board. Some are simple, and others are more complicated, and all of this complicates your decision more. Is it worth spending more money for the newest and greatest?
What features do you need? Let’s start comparing.

Buying Guide

Performance is paramount when you are shopping around for your car battery tester based on features, quality, price and capabilities. Being proactive and testing your battery every six months or so significantly helps you catch a problem before it arrives and surprises you. Testing your own battery with most car battery testers is easy. First, you need to locate the connectors of your vehicle and make sure they are cleaned of dust, dirt and corrosion. Attach the connectors to your vehicle, being sure they are correctly matched up with the positive and negative charge. Turn the battery tester on. From here, the battery tester should do it’s job. The more simple models will most likely be complete. If you have one that tests other components such as the alternator, other steps may need to be taken. There are a few important factors that are best tailored to your specific wants and needs that you need to consider. Let’s take a look.

Price

First, price is most likely the biggest factor here. It is true, you get what you pay for. There are a few testers on this list that are on the cheaper end, but are very limited in their functions. But if you are looking only for a tester that tests your battery and produces a pass or fail rating, then options like both Amprobe models and the Innova are a great option.

Versatility

Having many different functions on your tester is a huge win. The Ancel model will tell you so many different variables including CCA ,AH ,JIS, IEC, BCI, GB and more. It will also tell you the voltage power and can test your alternator. The Cartman, Clore and Topdon models also have the ability to test your alternator. One product, the Solar model has the ability to print the results out for you. Having the ability to perform a wide range of functions is key when deciding which tester to put your money into.

Safety

Some of these models may be considered to be safer than others, and safety is always a priority, especially when dealing with anything electrical. The Ancel model has an insulated cable, specifically designed and addressed for safety. The Foxwell brand tester has all-metal spray gold on its clamps which are spark-proof and offer short circuit protection and the Schumacher product is said to be built to be shock resistant.

Language

Although this may not apply to all consumers, to some, it is most likely the most important. A few of these testers have the ability to toggle between different languages settings. The models listed above with this feature are the Foxwell and Topdon models.

Conclusion

It’s the best decision that you could have made to invest in a vehicle battery tester. When you are shopping for the best battery tester for your vehicle, many factors are going to come into play when you are making a consumer decision. Deciding which features you require should be your first step. If you decide simplicity is your goal and you really only have one vehicle battery you are testing, then you will be able to go cheaper and chose a simple tester. However, if you have specific batteries that need to be tested, or a wide range of batteries, your choices may become more limited. Maybe you have different systems under your vehicle’s hood that need to be tested.

Keep in mind that price is a huge component in your decision. Remember that you truly do get what you pay for. More basic car battery testers may not perform as well as those specifically designed to meet a specific need. Paying a little extra for the best product will pay off in the long run.

Hopefully you were provided with some great options above that best suit your needs so you are prepared to make your decision. With so many options out there, you are guaranteed to find your winner.
