Portable Battery Tester

The Dlyfull B1L is a compact voltmeter that checks the remaining charge in common household cells. It works with 1.5V AAA, AA, C and D alkaline batteries, 9V blocks and button-cell types. The unit weighs 70g and fits in a tool pouch or drawer for quick access.

Compatibility Check

Verify that the cells you want to test fall within the supported voltage range of 1.2V, 1.5V, 3.0V or 3.7V for button and disposable chemistries. The tester does not analyse rechargeable packs or measure internal resistance. Ensure you can make firm contact with both terminals on each battery.

Sustained Use Behaviour

The device draws operating power directly from the battery under test, so it requires no separate supply during repeated checks. Its three-colour LED bar shows Good, Low or Replace status instantly. Continuous testing of large quantities will not heat the unit or degrade its reading consistency.
