Test device for many battery and rechargeable battery types

The compact and user-friendly tester checks the energy content of the most common primary batteries and rechargeable batteries within a very short time. This makes it easy to see whether your rechargeable battery still has sufficient power or should be replaced.

LC display

With decimal display of the battery voltage in volts and additional bar display with 22 segments

Simple operation

The voltage of the battery type to be tested is set using the slide switch on the side: 1.2 V NiMH battery/1.5 V battery/3 V lithium battery/3.6 V Li-ion battery
  • Pull out the battery compartment on the side
  • Insert battery with correct polarity.
  • Close the battery compartment.
  • Display appears
A 9 V block can be tested directly on the contacts. The position of the slide switch is not relevant for this. The tester itself does not require its own battery for power supply.
