Typically, the digital displays are much easier and comfortable to read when compared with the analog testers. Sometimes, the digital display includes a back-light, which makes it much easier to read and perfect for nighttime use. However, the digital car battery tester will cost you a little much than the analog one.

Voltage Versatility

Most of the battery testers available in the market are designed to test one specific types of battery. It is okay to buy such tester if you just need to check a specific type of battery. However, you can consider buying a tester which supports voltage alternation on a different scale. It can allow you to check other batteries too rather than your car’s battery. Some of the battery tester model available in the market can check the batteries from 4v to 20v. Such a wide range will be highly beneficial if you are a DIY worker who often deals with electric components.

Ease of Use

Usually, car battery testers are a simple and straightforward device. However, nowadays, there are a lot of models in the market which are equipped with the complex user interface. Moreover, some of them include wide arrays of features which you may not require. You should go for a simpler tester which can only do what it needs to do so that you can use it quickly whenever required without going through the complex procedures.

Construction

You may not want your car battery tester to tear off after using for a while. There are a lot of battery testers available in the market which has cheaper construction to compromise with the price. Such products may break or get damages while using. Try to choose a battery tester that comes with proper construction so that you can use it without any issues for a long-term.

How to Extend Your Car’s Battery Life?

As like as the other batteries such as the smartphone and laptop, the battery of your car also become unusable after a certain period of time. The usual car lead-acid car batteries stay okay around 42 months but depending on various aspects; the battery life can vary on a large scale. Here are some tips which may help to extend the car’s battery life.

01. Keep your battery fastened tightly

Vibration can shorten the lifespan of your car’s battery. So fasten the car’s battery in the right position and keep the clamp properly positioned. It is especially important for you if you often need to ride on the bumpy roads. Such roads can deposition the car battery much often.

02. Avoid short rides

An amount of charge is deducted from the battery every time you start the car’s engine. As a result, if you ride on a short distance frequently, then there is a chance of reducing the car’s battery life. Moreover, it doesn’t allow the battery to be fully charged. So avoid short rides and go for longer rides frequently to keep the battery upright.

03. Keep the lights off when you exist

Car lights are highly powerful, and they require a huge amount of charge. Keeping the lights on without any reason will increase the chance of battery life reduction. Keep the lights off if they are not necessary to reduce the draining of the battery.

04. Keep it clean
