Universal Battery Tester
The ZUFECY BT-189 checks remaining capacity for AA, AAA, C, D, 9V, and 1.5V button cells using a clear digital display. It measures 3.64" x 2.44" x .55" and is built from ABS plastic for durability. Operation is immediate: simply insert a battery to see its health status on the DT168 Pro screen.
Household and travel use
This tester suits anyone needing quick voltage checks on common cylindrical and button cells at home or on the move. It is not for users who require load testing, internal resistance readings, or support for rechargeable pack voltages beyond the listed types.
Digital voltage readout
The defining specification is the DT168 Pro digital display that shows remaining life instantly upon battery insertion. This single feature determines whether the tool matches the buyer's need for simple, portable voltage verification without leads or settings.

Questions about this item
Does the DT168 Pro display module need calibration or replacement after long-term use?
The DT168 Pro digital display is built into the BT-189 housing and has no user-replaceable parts or calibration procedure mentioned.
What stops the BT-189 from testing a 1.5V button cell continuously for hours?
The tester draws its operating power from the battery under test, so the cell itself depletes long before the unit reaches any thermal or time limit.
Does the ABS plastic case get warm or make noise when the BT-189 runs all day?
The BT-189 has no fan or active circuitry beyond the display, so it stays silent and at ambient temperature during extended use.
