AliExpress alternative to the Aneng Battery Tester with LCD Display

The verifier returned a 'same_product' verdict, but with meaningful caveats. The AliExpress listing specifies model BT158 while the reviewed product carries no model number, so an exact model-level match cannot be confirmed. Additionally, the display on the AliExpress unit is a color-coded analog LCD bar graph rather than a numeric digital readout, which may represent a functional difference from the reviewed unit.

According to the stored listing data, the tester is designed to check C, AA, AAA, D, N, 9V, 1.55V, and universal button cell batteries. This wide compatibility makes it practical for households with mixed device ecosystems, though you should confirm the physical slots can accept the specific button-cell diameter you need before purchasing.

The bar graph display provides a visual 'good/low/replace' zone reading rather than a numeric voltage or milliamp-hour figure, which is sufficient for quick capacity sorting but not for precision measurement work. If you need an exact voltage readout, the analog bar format on this BT158 listing may not match what you saw in the written review, so weigh that display difference carefully.

The AliExpress price of $3.23 puts this firmly in the budget-tool tier, where the plastic housing and contact springs are functional but unlikely to match the tactile quality of a higher-priced tester. The 960 orders and 4.90 rating suggest buyers find it reliable at this price point, but the unconfirmed model number means you cannot rule out minor internal component variations versus the reviewed product.

The listing title includes the term 'Capacitance Detector,' but the stored facts describe it as a battery voltage and capacity checker across standard consumer cell formats. There is no stored specification confirming it measures capacitance in the electronics sense (Farads); the word likely refers to remaining battery capacity rather than component capacitance testing.

Yes, the supported voltage range explicitly includes 1.55V, which is the nominal voltage of SR-series silver-oxide button cells commonly found in watches, calculators, and hearing aids. Confirm that the physical slot dimensions match your specific button-cell diameter, as the listing does not itemize which SR sizes the contacts accommodate.
