CE Custom 1.5V 3V Button Cell Phone Digital Watch Battery Tester

This professional battery tester provides comprehensive testing for 1.5V and 3V button cell batteries used in watches and small electronic devices. The non-contact testing method allows you to check battery power without opening watch cases. When a battery is low, the tester provides both audible sounds and visual lighting alerts, warning customers in advance that their watch requires a new battery. This efficient tool helps identify whether a quartz watch needs battery replacement or repair before case opening, saving time and preventing unnecessary damage.

The tester effectively evaluates 1.55V silver oxide batteries, 3V lithium batteries, as well as mercury and alkaline button cell batteries. Its compact design (56×56×24mm) makes it highly portable for professional use in watch repair shops, electronics stores, and manufacturing facilities.
