Universal Battery Checker

The BT-168 is a compact, self-powered tester that reads AA, AAA, C, D, 9V and 1.5V button cells without needing its own battery. Two units are included, each weighing 48g and measuring 109×59×25mm. An analog needle moves across green, yellow and red zones to show Good, Low or Replace status in seconds.

Home Users Not Lab Technicians

Suits anyone who wants a quick, portable way to sort household cells before use or storage. The simple voltage check is not a professional analyser, so buyers who need precise capacity readings, internal-resistance data or logarithmic discharge curves should look at dedicated test equipment instead.

Self-Powered Analog Display

The decisive spec is that the tester draws operating power directly from the cell under test, so it never needs a separate battery and is ready instantly. This keeps the tool light at 48g and eliminates the frustration of a dead tester battery when you need to check a spare.

The analog needle moves across green, yellow and red zones within three seconds, giving an instant Good, Low or Replace indication.

Two BT-168 testers are included; no separate battery is required because each unit draws power from the cell under test.
