Versatile Battery Tester for Household Cells

The ANENG BT189 checks voltage on AA, AAA, C, D, N, 9V, and 1.5V or 3.7V lithium cells, plus CR2032, LR44, and L736 button types. It suits anyone who keeps a drawer of mixed batteries and wants a quick health check before use. The digital LCD shows poor, weak, or good status at a glance. No internal power source is needed; the unit draws energy from the cell under test.

Replaces Guesswork and Single-Type Checkers

It removes the need to guess remaining charge or to own separate testers for cylindrical and button cells. The jump is worth it when you regularly sort rechargeable and disposable packs and want to avoid tossing cells that still hold useful voltage. Note that the device must not be powered by rechargeable batteries and should not be used to test them.

Simple Insert-and-Read Operation

Insert a battery into the matching contacts and the LCD reads voltage immediately. The tester weighs 0.04 kilograms and fits in a tool pouch or drawer. Common issues include inserting a cell backwards or trying an unsupported chemistry, which yields no reading. Ensure firm contact on the sliding rails for button cells to avoid false low-voltage indications.
