Testing device for various types of rechargeable batteries and batteries. This compact and user-friendly tester quickly checks the energy content of the most common batteries and rechargeable batteries. It is easy to see whether your battery still has sufficient energy or should be replaced.

The LC display shows the battery or rechargeable battery voltage in volts with a decimal display and an additional bar graph with 22 segments.

Easy operation: The voltage of the battery or rechargeable battery type to be tested is set using the side slide switch: 1.2V NiMH battery, 1.5V battery, 3V lithium battery, or 3.6V Li-Ion battery.

1. Pull out the side battery compartment
2. Insert the battery correctly according to polarity
3. Slide the battery compartment back in
4. Display appears

A 9V block can be tested directly at 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.

The following battery sizes and types can be tested:
1.5V batteries: AAAA (Mini), AAA (Micro), AA (Mignon), C (Baby), D (Mono), N (Lady);
1.2V NiMH/NiCd batteries: AAA (Micro), AA (Mignon), C (Baby), D (Mono);
9V battery: 9V block (E);
9V NiMH battery: 9V (8.4V) block (E);
3.6V/3.7V Li-Ion batteries: 14500, 14650, 16340, 17500, 18500, 18650, 22650, 26650;
3V lithium button cells: CR2025, CR2032, CR2320, CR2330, CR2354, CR2430, CR2450, CR2477, CR3032;
