Renata Battery Tester - TS-BWT94

The Renata BWT94 Watch & Battery Tester lets you quickly determine whether a quartz watch needs a battery replacement or professional repair. It features two testing positions: Silver 1.55V for low- and high-drain silver oxide, multi-drain, and alkaline button cells, and Lithium 3.0V for CR and BR lithium batteries. The tester checks both battery voltage and potential mechanical faults, is powered by a replaceable CR2430 lithium battery, and includes an automatic two-minute shut-off. Swiss-made.
