Guide: Questions you should ask yourself before buying a battery tester
Who is a battery tester suitable for?
Battery testers can tell you exactly what the current condition of your battery is. Just imagine that you have an important appointment and the car won't start. Either you wait for a breakdown service or pay a taxi for a jump start.
This is exactly why it makes a lot of sense for you to get yourself such a battery tester. It can save you a lot of stress, hassle, waiting and money if you regularly check your car battery with a battery tester.
Is a battery tester suitable for a truck, a car or a motorbike?
This is exactly the question we want to help you with in order to find the right device for you and to protect you from unforeseen surprises. So if you have such a device, at least you will no longer be late because of the car battery.
In which version should I buy a battery tester?
First, you should check if your car has 12 V connections. Actually, every car should have them nowadays, but there are always some exceptions, e.g. old cars.
In addition to your navigation device or charging cable, you can also connect a battery tester to the connections.
Both the cigarette lighter socket and the ring lug battery tester reliably show you the status of your battery.
What does a battery tester cost?
We recommend that you do not limit yourself to price when choosing a battery tester.
It is always best to look at the price-performance ratio to find the right device. First of all, you have to decide whether you need a battery tester with a ring lug connection or a cigar lighter connection. Depending on this, the price will vary slightly to greatly.
What are the alternatives to a battery tester?
As you can see, you wouldn't really have an alternative, you would just have your battery tester task done by someone else for a fee.
So we recommend that you get your own battery tester at best, as you can easily save money, time and workshop visits. A battery tester would therefore be a sensible investment.
You should always pay attention to the price-performance ratio and not buy the cheapest battery tester. This way you can use the battery tester for a long time.
Decision: What types of battery testers are there and which is the right one for you?
If you have reached the question of which battery tester is the right one for you, then this part is very important for you.
We will explain the two different types of battery testers and show you the advantages and disadvantages of each.
The following types of battery testers are available:
- Battery tester with cigarette lighter connection
- Battery tester with ring terminal
It is also a factor of suitability for everyday use and the question of cost that will ultimately bring the decision.
Of course, it is essential for you to know which type of connector your car has.
If you have both, you can easily choose between them, if not, your choice will be limited accordingly.
What distinguishes a battery tester with a cigarette lighter plug and what are its advantages and disadvantages?
A battery tester with a cigarette lighter plug can be conveniently connected to the 12 V port. The tester is powered by the current released by the car battery.
With this battery tester, you can easily see how your battery is doing.
However, it is recommended that you leave the car running during the test, as this will optimally protect the battery. Otherwise, the battery cannot be charged at the same time.
What distinguishes a battery tester with a ring lug connection and what are its advantages and disadvantages?
A battery tester with a ring terminal is similar to a jumper cable. It has two cables, which you then connect to the positive and negative terminals.
But you should make sure that you wrap rubber gloves or non-conductive material around your hands when using this battery tester, otherwise there is a risk of electric shock.
Since this type is connected directly to the battery, it is more accurate and you can see the condition of the battery with your own eyes.
If you have ensured your safety, then nothing stands in the way of a battery test and you can then take optimal care of your battery.
Buying criteria: These are the factors you can use to compare and evaluate battery testers
In the following, we will show you which aspects you can use to decide between the many possible battery testers.
The criteria you can use to compare battery testers include:
- Cable length
- Temperature display
In the following paragraphs, we will explain what is important in the individual criteria.
The display is one of the most important aspects of a battery tester. The more data about the battery's condition is shown on the display, the better. It is best to make sure that it is not a mini-screen where you have to read the individual values with a magnifying glass.
So the more accurate and precise a display is, the easier it is for you and also easier on your eyes. With a battery tester, it is essential that the volt display and the temperature display are shown as information. If these values are missing, the device is doing something wrong.
|Cigarette lighter||Very good||Accurate||No cables|
|Ring lugs||Good||Very accurate||Medium length|
With most devices, a long cable is extremely practical to increase or even guarantee your comfort.
If you have a very short cable, you will have to literally stick to the device to be able to read anything at all. However, you must distinguish between the different types of connection.
With the ring lug device, it can make a lot of sense if you tend to use a longer cable. With the cigarette lighter type, it makes less sense.
The display is usually directly on the adapter, so you don't really need a cable for it. All you have to do is insert it into the 12 V plug and turn the keys at least until the battery is switched on.
The temperature indicator is the most important point, next to the volt indicator. As mentioned before, the temperature display should be present at all costs.
Just imagine that your battery generates excessive heat and you don't notice it. This will cause enormous damage to your battery and sooner or later it will give up the ghost.
The excessive heat is also not kept cold by a cooler, such as an intercooler.
If you want to have fun with your car battery for a long time, you should check not only the voltage but also the temperature regularly.
You should pay attention to these evaluation points so that you can find a good battery tester and enjoy it for a long time.
Readability is understood here as screen sharpness or sharpness. If the display is very hard to read, we would advise you not to use this device. It should be sharp and not strain your eyes unnecessarily.
It doesn't have to be an UltraHD resolution screen, but it should at least be readable.
The more accurate the better; that is mostly true. But it is also true that the more accurate the device, the more expensive it is.
So you don't need a specially made high-tech device to check your battery. A conventional device will do. But it should still be accurate, otherwise it will show the correct reference value but the actual value will be wrong.
The usability is determined by the user-friendliness. The easier a device or product is to operate for a customer, the higher the usability.
However, you have to distinguish between the ring eye types and the cigarette connection types.
The operation of the cigarette connection battery testers is relatively simple. All you have to do is plug the adapter into the 12 V connection and you're done.
The ring terminal battery tester is a little more complicated. It is similar to a jumper cable. Connect one end to the positive terminal and the other end to the negative terminal and you're done.
