BT88 Battery Tester – Quick Check for 1.5V and 9V Batteries with Analog Display

Versatile Analog Tester for AAA, AA, C, D and 9V Batteries

This analog battery tester is a simple, reliable, and easy-to-use tool for quickly checking the status of the most common battery types. With the help of an easy-to-read analog needle display, it instantly shows the remaining capacity of the battery, classifying it into zones such as "Fresh", "Usable", or "Depleted". The tester is specifically designed for 1.5V batteries (AAA, AA, C, D) and 9V batteries (6F22/PP3).

The working principle is intelligent: the tester does not simply measure the no-load voltage, but places a controlled load on the battery (4Ω for 1.5V and 215Ω for 9V), simulating real usage. This gives a much more accurate idea of the actual remaining capacity and the battery's ability to deliver current. Mounting the battery is intuitive via marked contacts. This tester is an essential accessory for any household, offices, shops, service centers, and educational institutions, saving money by preventing the premature disposal of still usable batteries and increasing the efficiency of battery-powered devices.

Note: The BT168 pointer type can only measure 1.5V and 9V batteries!
