Versatile Battery Tester

The KKEANIC tester checks AA, AAA, AAAA, C, D, N, 9V and common button cells such as CR2032 and LR44. It also handles 1.2V rechargeable AA, AAA and AAAA types. A smart detection system prevents incorrect testing. The package includes the tester and a user manual.

Real-Load Voltage Measurement

Built-in precision resistors apply specific discharge loads for each chemistry: 2075 ohms for alkaline AA through D, 3040 ohms for 1.2V rechargeables, 30100 ohms for CR2 or CR123A, 1K1.5 ohms for LR44, 1K3 ohms for CR2032 and 1K9 ohms for 9V cells. The LCD shows exact voltage plus a coloured Good, Weak or Poor bar. This simulates real-world demand better than open-circuit checks.

Replaces Guesswork And Basic Checkers

It upgrades from simple voltage-only probes that cannot reveal capacity under load. The jump is worth it when you need to know whether a cell will actually run a device, not just show a surface voltage. It does not test automotive or high-capacity lithium packs.
