Battery tester Varta 00893 101 111 LCD digital handheld for AA AAA 9V button cells

Handheld digital battery tester Varta 00893 101 111 with an LCD display provides quick voltage-based checks of common consumer cells. The compact device measures AA and AAA cylindrical cells, 9V rectangular batteries and various button cells, indicating remaining charge level on the screen. It is designed for simple, on-demand verification of batteries used in household electronics, toys, remotes and small tools, enabling identification of weak or depleted cells before installation.

Advantages

The tester offers a clear LCD readout that shows voltage and an interpreted charge level, allowing fast assessment without load testing. Its handheld form factor and straightforward contact points make measurement convenient for single batteries or batteries in small devices. Low weight and compact size support storage in a drawer or toolbox for occasional checks. The device operates on standard internal power and presents results instantly, reducing the need to rely on device performance as the only indicator of battery state.

Suitable for

• Checking AA and AAA rechargeable and alkaline cells before use
• Testing 9V batteries in smoke detectors, multimeters and other equipment
• Verifying button cells used in watches, calculators and small remotes
• Quick diagnostics during troubleshooting of toys, remotes, clocks and handheld devices

Key specifications

• Measurement method: voltage-based digital measurement with LCD readout
• Supported cell types: AA, AAA, 9V and common button cells
• Display: backlit LCD indicating voltage and charge level
• Form factor: handheld, lightweight enclosure for manual operation
• Contacts: contact probes suitable for cylindrical, rectangular and coin/button cells

How to use

Place the battery tester on a stable surface and power it on if required. Align the battery with the corresponding contact points: position cylindrical cells so both ends touch the probes, place 9V batteries against the rectangular contact area, and hold button cells on the coin contacts. Read the voltage and charge level on the LCD display. For consistent results, ensure contacts are clean and that the battery terminals are not corroded. Repeat the measurement after a short rest if readings appear inconsistent.

Recommendations

Use the tester in room-temperature conditions for best accuracy and avoid applying excessive force to contact probes. Do not attempt to test batteries that are visibly damaged, swollen or leaking. Store the tester in a dry place and periodically clean contact points with a dry cloth to maintain reliable measurements.
