Ancel Automotive Load Battery Tester (BA101)

Ancel Automotive Load Battery Tester (BA101)

This small tester complies with important battery standards like JIS, SAE, EN, DIN, and IEC and may be used on a variety of 12-volt batteries. It is made to measure the battery’s actual cold cranking amps capacity as well as the battery’s health simply, fast, and correctly. The battery’s CCA or AH value, charge percentage, voltage, internal resistance, and battery health percentage are all displayed for each reading.

The only feature we wish this battery tester had was the ability to test 24-volt systems as well, but this isn’t a big concern if you don’t drive a car that uses a 24-volt battery. However, we would like to see it for a little bit more adaptability at this price point.

Features

How to Check Your Car’s Battery

It’s time to check the state of your battery after buying a car battery tester. Although most testers will come with comprehensive instructions on how to use the particular gadget, there are some basic guidelines and suggestions to keep in mind.

  • It’s usually advised to put on a pair of rubber gloves and safety goggles before doing any work with your batteries. Your hands and eyes will be shielded from acid by gloves and goggles.
  • Make sure your car’s ignition is off and all of the lights are out before you proceed.
  • Connect your battery tester’s positive lead to the battery’s positive terminal.
  • Connect your battery tester’s negative lead to the battery’s negative terminal.
  • Verify the battery voltage on your car. Your battery is in excellent condition if it displays a voltage that is higher than 12.6, though (100 percent). Your battery is in good condition if the voltage level is around 12.4 volts or around 75 percent. Readings of 12.2 volts and lower signify a faulty battery because 12.2 volts is approximately 50% of the full value.
  • After assessing the condition of your battery, first, remove the negative terminal. You should use a battery terminal puller to remove the clamps if they are difficult to remove otherwise.
