The Battery Tester with LCD screen is a versatile tester for checking 7 different types of batteries, such as AA/C/D/N/AAA/9V. During the battery test, the condition of the battery is displayed on an LCD screen. It measures standard 1.5 V and 9 V batteries, as well as small button-type batteries for watches and other small devices.

It features an LCD screen that shows the voltage indication of the battery:

• Measurement for 1.5 V batteries:
  • Indication on the screen from 1.2 to 1.5 V shows that the battery is good.
  • Indication on the screen from 0.9 to 1.1 V shows that the battery is low on power.
  • Indication on the screen below 0.8 V means the battery needs replacing.
• Measurement for 9 V batteries:
  • Indication on the screen from 6.3 to 9.0 V shows that the battery is good.
  • Indication on the screen from 4.5 to 5.4 V shows that the battery is low on power.
  • Indication on the screen below 3.6 V means the battery needs replacing.

Note: The duration of the battery test should be as short as possible to avoid unnecessary battery discharge.
