Ansmann 1900-0035 Button Cell Battery Tester – A Compact and Reliable Solution for Coin Cell Testing

When it comes to checking the health of button cell batteries, having a reliable tester is essential. The Ansmann 1900-0035 Button Cell Battery Tester is a compact, easy-to-use device designed to test both alkaline and lithium coin cells efficiently. With its LED display and automatic voltage recognition, it provides a quick and accurate assessment of battery capacity, making it a must-have tool for anyone who frequently uses small electronic devices.

Key Features

  1. LED Capacity Indicator – The tester features a clear LED display with five lights (red, orange, and green) that indicate the remaining capacity of the battery. This visual feedback makes it easy to determine whether a battery is still usable or needs replacement.

  2. Automatic Voltage Recognition – The device intelligently detects whether the inserted battery is alkaline (1.5V) or lithium (3V), eliminating the need for manual adjustments.

  3. Compact and Portable – Measuring just 55 x 45 x 13.5 mm and weighing only 17 grams, this tester is small enough to fit in a pocket or toolkit, making it ideal for on-the-go use.

  4. Includes CR1620 Battery – The tester comes with its own CR1620 button cell for operation, ensuring it’s ready to use right out of the box.

  5. Simple Operation – Just place the battery in the designated slot, press down, and the LEDs will instantly display the battery’s condition.

Why This Tester Stands Out

Unlike generic battery testers that require guesswork, the Ansmann 1900-0035 provides a straightforward, no-nonsense approach to checking coin cell health. Its ability to test both alkaline and lithium batteries makes it versatile, while the LED indicators offer a clear, intuitive readout.

One satisfied customer noted:
“This little gadget is brilliant—saves me from guessing whether a battery is dead or just weak. The LED lights make it super easy to understand, and it’s small enough to keep in my toolbox.”

Another user praised its efficiency:
“I use this for checking hearing aid batteries, and it works perfectly. No more wasting time with questionable batteries—just a quick test and I know if it’s good to go.”

Final Verdict

The Ansmann 1900-0035 Button Cell Battery Tester is a reliable, user-friendly tool that takes the guesswork out of battery testing. Whether you’re maintaining small electronics, medical devices, or key fobs, this tester ensures you always know the true state of your coin cells.
