Universal Battery Tester

The BT-168for checks voltage on AA, AAA, C, D, 9V and 1.5V button cells. It draws operating power directly from the cell under test, so no internal battery is needed. A moving needle on an analog scale shows good, low or replace status in seconds.

Household users checking mixed cells

Suits anyone who keeps a drawer of common alkaline or rechargeable sizes and wants a quick pass-or-fail reading. Not for technicians who need precise capacity measurements, lithium-ion cell support or a digital display with exact voltage values.

Voltage-based status zones

Green indicates 1.5 V cells above 1.28 V and 9 V cells above 7.8 V. Yellow covers 1.27 V down to 1.15 V for 1.5 V types and 7.7 V down to 6 V for 9 V types. Red means replace below 1.15 V or 6 V respectively.

Questions about this item

How long can I keep the BT-168for connected before the tested battery drains noticeably?

Keep test times as short as possible; the unit draws its operating power directly from the battery under test, so prolonged contact will reduce that battery's charge.

Does the analog needle movement generate any audible noise or heat during continuous testing?

The tester has no internal power source, fan or electronic circuitry, so it produces no noise and no measurable heat while in use.

Which battery types can I check immediately without buying extra adapters or contacts?

The built-in contacts accept AA, AAA, C, D, 9V PP3 and 1.5V button cells directly; no separate holders or leads are required.
