Battery Tester TFA-Dostmann 98.1126.01 LED Display 89mm Width

The TFA-Dostmann 98.1126.01 Battery Tester is a compact, robust device for quickly checking the charge state of common batteries and accumulators. It supports cylindrical cells (AAA, AA, C, D), button cells with nominal voltages of 1.2 V, 1.5 V or 3.0 V, and 9 V block batteries. The tester draws only the short measurement current from the battery under test, so it requires no separate power supply and is always ready to use.

Advantages

The LED display provides a clear readout of the battery voltage and charge condition in volts, enabling fast assessment of whether a battery still has sufficient capacity for devices such as remote controls or flashlights. Its small size (89 mm width) and sturdy build make it portable and suitable for both household and professional use. The tester’s simple operation allows quick checks without technical setup.
