The LCD displays the measured voltage in volts and the battery status on an easy-to-understand scale ranging from fully charged to empty.
The tester is designed for AA, AAA, C, D and 9V batteries, as well as button batteries with voltages of 1.2 V, 1.5 V and 3.0 V.
Thanks to the short-term measurement, the tester does not require its own battery or any other power source.
The TFA BatteryCheck battery tester is a practical aid for quickly checking whether batteries are still usable. It is suitable for AA and AAA batteries, as well as C, D and 9V batteries and button batteries with voltages of 1.2 V, 1.5 V and 3.0 V.
The device performs short-term measurements and therefore does not require its own power supply. The LCD displays the current voltage in volts and simultaneously provides a clear assessment of the remaining capacity using a colour-coded scale.
