BT169 Digital Household Battery Tester

Check the voltage of a supported household battery before deciding whether to keep it in use. The BT169 displays a digital reading without needing a separate power supply.

✅ Sort batteries by a measured reading - A voltage display gives you a reference beyond guessing which loose battery has been used.

✅ Test without fitting a power battery - The tester's no-external-power format avoids a separate battery for the tester itself.

A Quick Voltage Check for the Battery Drawer

Use the tester only with the battery formats and voltages supported by its actual contacts. The specified measuring use covers 1.2 to 4.8 V batteries and a separate 9 V battery test.

A voltage reading is a useful check rather than a measurement of remaining capacity or guaranteed runtime. Match the result to the battery type and the equipment you intend to power.
