Universal battery tester

The BT-168 checks voltage on AAA, AA, C, D, 9V and 1.5 V button cells. It fits rechargeable and standard chemistries in one compact unit. No internal power source is needed; the device draws energy from the cell under test.

Home users with mixed battery types

Households that keep several sizes on hand can verify each one quickly. Technicians who need precise capacity readings or data logging should look elsewhere. Builders requiring automotive or high-voltage testing will not be served by this tool.

Color-coded analog scale

A moving needle shows green for good, yellow for low and red for replace or recharge. The scale is calibrated for 1.5 V and 9 V cells and gives an immediate visual verdict without buttons or menus.

Questions about this item

How much space does the BT-168 need on a workbench?

The unit measures 17 cm long, 10 cm wide and 3.5 cm high, so it fits in a small drawer or tool tray.

How do I start a test and what mistake should I avoid?

Place the battery against the correct contacts for its size — 9 V on the top posts, cylindrical cells in the side slots — the needle moves instantly without any power switch; the common error is reversing polarity on button cells.

What part of the BT-168 will need attention over time?

The spring-loaded contact arms and sliding selector can accumulate oxide or loosen with repeated use; clean the contacts occasionally and check that the selector clicks firmly into each position.
