Magnetic Battery Tester for Household Cells
The Dlyfull B1T checks AA, AAA, C, D, 9 V and 1.5 V button cells without a built-in power source. Its magnetic hold keeps cylindrical batteries steady during testing, though the 9 V terminal has no magnet. Home users and hobbyists get an instant health reading without fiddly contacts.
Passive Testing with Colour-Coded Readout
The tester draws its operating power from the cell under test, so no external supply or battery is needed. A three-colour LED shows Good in green, Low in yellow and Replace in red. Current draw stays minimal because the circuit only activates while a battery is seated.
Manual and 18-Month Warranty Included
The package supplies a welcome guide that explains the three LED states and proper terminal alignment. An 18-month warranty and 24/7 customer support cover defects, but the tester itself has no internal battery to replace. Buyers needing rechargeable-cell cycling or data logging will need a different instrument.

Questions about this item
How do I position a AA battery so the magnetic hold keeps it steady during testing?
Align the positive and negative terminals with the tester contacts; the magnetic hold secures AA, AAA, C and D cells automatically, but the 9 V terminal has no magnet so you must hold that battery in place manually.
What part of the Dlyfull B1T will need replacement after the 18-month warranty period?
The tester itself has no user-replaceable components; only the batteries you are checking will need replacement when the display shows "Replace" (red).
How many consecutive tests can I run before the "Low" (yellow) indicator becomes unreliable?
The tester draws no built-in power supply, so sustained use does not degrade its readings; each test gives an immediate Good, Low or Replace result regardless of how many you perform in a row.
