Universal Battery Tester for Household Cells

The DLYFULL B2 checks voltage on AA, AAA, C, D, 9V and button cells using a built-in LCD. It fits home users and technicians who need a quick way to sort good cells from dead ones without a multimeter. The tester includes one AAA alkaline cell for immediate operation. It is not designed for rechargeable chemistries.

Pocket-Sized Passive Operation

The unit measures 5.2 by 3.46 by .94 inches and weighs 115 grams, drawing power only from the battery under test. No external supply or internal rechargeable cell is used, so there is no fan noise or standby drain. The anti-slip finish gives a secure grip during rapid checks.

Replaces Trial-and-Error Device Testing

It removes the need to insert batteries into radios or toys to gauge remaining life. The LCD shows poor, weak or good status at a glance, helping users avoid unnecessary recharges of primary cells. Buyers who need to test rechargeable NiMH or Li-ion packs should choose a different instrument.

Questions about this item

How do I install the included AAA battery and what step do people often miss?

Open the battery compartment, insert the supplied AAA alkaline cell with correct polarity, then close the cover; the common mistake is forgetting to remove the plastic insulator tab before first use.

What maintenance or replacement will the tester need later?

The only replaceable part is the internal AAA alkaline battery; when the LCD dims or readings become erratic, swap it for a fresh AAA cell.

What limit appears first during sustained use?

The tester is not powered by rechargeable batteries and must not be used to test rechargeable cells; attempting to do so will give incorrect readings and can damage the unit.
