Battery Tester BT169, Digital Household Voltage Check
✅ Sort the drawer. A measured voltage reading separates the cells worth keeping from the ones to replace.
✅ Skip the extra battery. The tester runs without a separate power cell, so there is nothing else to fit first.
✅ Check before you fit. Test a supported cell before putting it into a remote, clock or other household device.
✅ Know the limits. A voltage figure is a check, not a statement of remaining capacity or guaranteed runtime.

A BT169 tester that shows a digital voltage reading for specified 1.2 to 4.8 V cells and 9 V batteries. It needs no separate power battery, so the check happens with the tester alone. Treat the figure as a voltage check rather than a measure of remaining capacity or runtime.
