Circular Type Watch Battery Tester 1.5V 3V Button Cell Battery Analyzer

This professional battery testing instrument serves as both a pulse tester for watch batteries and an analyzer for 1.5V and 3V button cell batteries. The device provides non-contact testing capability, allowing you to assess battery power levels before opening watch cases. When a battery is low, the tester emits an audible alert with visual lighting indicators, providing clear warnings that a watch requires battery replacement.

Ideal for watch repair professionals and jewelers, this tester helps identify whether a quartz watch needs a new battery or requires mechanical repair before case opening. The device effectively detects mechanical defects and voltage level deficiencies, saving time and preventing unnecessary disassembly.

The BT-3A tester is effective for analyzing 1.55V silver oxide batteries, 3V lithium batteries, as well as mercury and alkaline button cell batteries commonly used in watches and small electronic devices.
