How to Choose the Car Battery Tester?
There are somewhere between oodles and scads of car battery testers in the marketplace. At first glance, most of them look remarkably similar. How do you pick from a field this large?
Here are a few points of differentiation and features to consider in a car battery tester.
1, Compatibility
Not all batteries are manufactured equally. Is yours a Maintenance-free, Gel, Absorbed Glass Mat, etc.? It’s important to know that your battery is a compatible type together with your charger.
Look under your hood and find what you’ve got. Then check the manufacturer’s specifications before you make a buy decision.
2, Type of Tester
Different testers check different aspects of your battery’s performance. Which kind you choose will be dictated by your unique requirements, or how interested you are in DIY under the hood.
3, Load Tester
A charger with a battery load test feature contains a large resistor. By engaging the resistor, the tester takes on a similar electric load as the starter engine would while cranking. The tester can thus determine if the battery can start the car.
Performing a similar test on a moving vehicle can diagnose the condition of the alternator, and inform you if it’s still able to charge the battery.
4, Data Output You Require
Analog battery tester
With an analog display, you won’t get as accurate a reading as with a digital. You will, nevertheless, get yourself a distinct idea of if the battery or system is performing within an acceptable range or not really.
This is because of the conveniently color-coded zones the needle passes through. They aren’t always readable in low light. However, they do provide a large amount of information at a glance.
Digital battery tester
A digital tester offers you a visible and precise result each time you check. You’ll know the exact reading without guessing or estimating, because of very low levels of charge. Also, they are readable under low light circumstances.

Precautions
A car battery is a core component of an automobile as it can power the car and all electrical parts like the lighting and even the engine. It is power in bulk. Keeping in mind that the battery itself is an electrical item and can be dangerous if not handled carefully. Extreme precaution is a must when working with batteries, whether acid ones or any other kind of batteries of high volts.
Even dead batteries can be dangerous, also if they are no longer fully charged. Battery leaks can be fatal. Some batteries release hydrogen when charged, and hydrogen is highly flammable. This is why when a battery is charged with gas, as long as a spark is generated near the terminal, a fire will occur. In the worst case, the battery can even explode, which can be even more dangerous.
It is strongly advised not to smoke near the battery, especially when charging. Remember, explosions while working on a vehicle are quite rare, but battery explosions are still dangerous because batteries contain acidic substances. Acid is undoubtedly not suitable for the skin, so wearing goggles, gloves, and long-sleeved shirts is a wise choice. Acid should be appropriately included, but you must never tip the battery over or let it go up the wrong way, and be very careful if the case breaks.
Conclusion
Car batteries are usually entirely accurate, but with so many different brands of equipment, each has some advantages. Some brands offer more features at higher prices, while others keep elements and prices at a basic level. However, depending on your requirements and budget, buying and carrying a best car battery tester is not a loss. One will be used.
FAQ
How can you tell if a battery is good or not?
1. If you look at the power observation port, you can see three colors. Green indicates sufficient power; black indicates a slight loss of power, and white indicates scrapped and needs to be replaced.
2. The battery voltage is measured by a battery tester. Under normal circumstances, the no-load voltage of the battery is about 13 volts, the full-load voltage will not be lower than 12 volts, and the starting voltage should not be lower than 9.5 volts.
3, Observe whether there is a noticeable expansion or bulging on both sides of the battery and whether there are white or green powder objects around the battery pile head, which means that there is a problem in battery performance.
How does a car battery tester work?
The battery tester works by testing the current from the battery. When something conductive touches both the negative and positive sides of the battery, the current is released. Many adventurous people use this principle to test 9 volt batteries and stick the contacts to their tongues. Anyone who has tried this method knows that a fully charged 9-volt battery will produce a small vibration. The battery tester does the same thing, using a conductive medium to measure the charge (amps) from the battery. Each tester also has a gauge that reflects the charge level.
