BT173 Household Battery Voltage Tester
Sort supported household cells with a quick voltage and bar-display check. The BT173 uses the tested battery for power and needs no separate supply. It is for users checking a cell before deciding where to use it.
- ✅ Check a cell without another battery — The tested cell powers the instrument.
- ✅ Read two visual references — A value and bar display show the described condition indication.
- ✅ Test different supported shapes — The tool names cylindrical, button and rectangular battery formats.
- ✅ Keep it in the battery drawer — A small body fits a household checking kit.
Use the correct contact and supported range
The stated ranges are 1.5–4.8V and 9–12V, with specific supported formats including AA, AAA, selected button cells and cylindrical lithium-ion cells. This is not a continuous 1.5–12V range or an all-battery guarantee.
A bar indication does not directly measure usable capacity or expected device runtime. Keep tests brief and confirm contact before interpreting a blank screen. Do not use it on vehicle starter batteries or other high-energy packs based only on voltage.
