Does the same tester work on all types of batteries?

If it is a universal car battery tester, then it does operate on all types of car batteries. Many of the best car battery testers can test a variety of types of batteries, but check first because not all battery testers are necessarily compatible.  

Some of these will work on “regular”, around-the-house batteries as well.  Check the product description to make sure it meets your needs.

What safety steps should I take when testing my battery?

  • Read the car battery tester manual, especially the safety measures section.
  • Turn off the vehicle’s ignition BEFORE you start, even before you remove the covers over the terminals.
  • Connect both leads to the battery before turning on the charger.
  • Make sure you connect the positive lead of the battery tester to the positive terminal of the battery and negative to negative. You could damage the battery and the charger if you switch the connections.

What exactly IS a car battery tester?

Car battery testers are electronic devices that check the status of the electric battery in vehicles. It is a fast and affordable method to test the status of your battery. The alternative is for a car electrician to check the battery; your car’s electronic system can’t monitor and diagnose the state of the battery.

It may be a simple battery tester that shows the charge rate of the battery, or it may be more sophisticated testing and diagnosing the complete charging system.  

Are battery testers accurate?

The accuracy of an automotive battery tester is easily indicated in the way the readings shown on the screen. Analog meters are easy to read; it merely indicates color-coded good or bad readings with an arrow, but not necessarily the best quality product for accurate readings. It isn’t as accurate as a product like the Motorpower BAT-250 digital battery tester that indicates readings at 0.01V.

The best car battery tester depends on what your needs are. If you want a primary product that you can use to test if the battery is fully charged or not, then an analog meter will give you the battery status quickly. If you are looking for high-quality technology, then the best battery tester for your need will be one that has a digital display.  

How do electronic battery testers work?

A traditional load battery tester requires the battery to be charged at 75% to give a reading. The electronic battery load tester is compact to hold in your hand and doesn’t require much amperage for testing purposes. An electronic battery tester applies a small amp load to the battery when testing it, which means it doesn’t need a fully charged battery for testing purposes.

An electronic battery load tester connects a lead between the battery tester and the battery to measure the current released from the battery. A healthy, fully charged car battery operates at about 12.6V or more; it increases to 13.7-14.7 volts when the engine is running.

Some of the best car battery testers also do conductance testing. It doesn’t drain the battery and can test a battery that is low or discharged without removing the battery from the vehicle.
