12V BLOW TA-01 Battery Tester

The practical BLOW car battery tester is a small, convenient device designed to quickly check the condition of a 12V battery and the vehicle's charging system. Thanks to its clear LED display and status indicators, it allows you to easily determine whether the battery is charged, requires recharging, or indicates a problem requiring inspection.

The tester is powered directly by the battery being tested, so it requires no additional batteries or external power. Simply connect the alligator clips to the battery terminals and read the result on the device's panel.

Quick 12V Battery Check

This tester allows you to quickly check the battery voltage in your vehicle. Once properly connected, the device automatically powers on and displays the current voltage on the LED display. It's a simple solution for basic battery diagnostics without the need for complex tools.

Clear battery status indicators

The tester's panel features practical LED markings that make it easy to interpret the results. The device provides information about the battery's charge level, including FULL, MEDIUM, LOW, EMPTY, and DEAD status. This lets you know at a glance whether the battery is in good condition or requires recharging or further inspection.

Charging system test

The tester also allows you to check the charging system's operation after starting the engine. GOOD and HIGH indicators indicate whether the alternator voltage is correct or too high. This useful feature helps determine whether the problem is with the battery itself or the vehicle's charging system.

Protection against incorrect connection

The device features a reverse connection indicator. If the terminals are connected incorrectly, the tester activates the REVERSE indicator and an audible alarm. This increases user safety and reduces the risk of errors during testing.

Simple operation without batteries

The tester requires no additional power supply. Power is drawn directly from the battery being tested, ensuring the device is always ready for use. Its compact size allows for convenient storage in a car, garage, or workshop.

Meaning of LED indicators:

• FULL – battery fully charged, normal condition
• MEDIUM – voltage slightly reduced, top-up recommended
• LOW – low energy level, charging required
• EMPTY – battery empty, charging required
