Best Car Battery Tester FAQ:
Q: What is a car battery tester?
A car battery tester is an electronic machine that tests electric batteries. They range from simple devices that test present cells and voltage output, to more complex models that analyze the condition of batteries and examine their accumulating charge and possible issues impacting their performance. Battery testers are either simple, or integrated. Simple car battery testers simply indicate the charge rate of the battery. However, more integrated devices are able to also check cranking voltage, and output voltage. They will also often check the CCA levels.
Q: How do I check my car’s battery?
Before you test your car’s battery with your new battery tester, always remember to read the user manual so that you can learn about the exact quirks of your particular device. However, as a general rule the process of checking your car’s battery should include:
ALWAYS turn off your ignition!!!
Taking off your battery’s positive terminal cover (while your ignition is still off!)
Connecting your battery to your battery tester with the provided cables by attaching the positive lead to the positive terminal, and the negative lead to the negative terminal.
Check your battery tester’s analysis and decide whether you need to give your car a jump, or replace the battery.
If you are unsure of what to do, check out some free online tutorials!
How do battery testers work?
A well-functioning automotive battery should be operating at 12.6 volts or more ands this should increase to around 14 volts when your engine is running. Battery testers are able to check the current that comes from the battery by connecting a conductive lead between the battery and the tester. Whether you are running a battery test, a system charging test, or an alternator test you will always connect the cables to your various terminals. The more sophisticated your battery tester model is, the more diverse functionality it will be able to analyze.
