Mercury Universal Analogue Battery Tester 600.098UK

Stop guessing whether your household batteries are depleted or still packed with life. The Mercury Universal Analogue Battery Tester (600.098UK) delivers fast, clear, and dependable diagnostic results for a wide variety of everyday cylindrical batteries and micro button cells.

Accurate Testing Under Real Load

Unlike basic voltage meters that test without resistance, the Mercury 600.098UK tests batteries under an active simulated load. This provides an accurate reflection of the cell's true operational capacity, preventing false "good" readings on exhausted cells.

Universal Household Compatibility

With an adjustable slider and dedicated 9V contacts, this versatile unit quickly tests:

• Standard Cylindrical Batteries: AA, AAA, C, and D sizes
• Block Batteries: 9V (PP3) square terminals
• Miniature Cells: 1.5V button and coin cells

Intuitive Tricolour Analogue Meter

The colour-coded gauge displays battery status at a glance with clear "Good" (Green), "Low" (Yellow), and "Replace" (Red) indicators, eliminating any confusion. Because the tester draws a minute amount of operating power directly from the cell being tested, it requires no internal batteries to function.
