Universal Battery Tester for Home Use

The EastyGold Bioamy voltmeter checks 1.5V and 9V cells including AA, AAA, C, D, 9V and button types such as 18650 16340 14500 10440 lithium cells. A three-colour pointer shows green for good, yellow for low power and red for replace. It suits households wanting a quick way to sort usable cells from dead ones.

Sustained Testing Behaviour

The analog needle responds instantly when a cell contacts both points and holds its position while the battery remains in place. No internal power source is required so the tool does not drift or shut down during extended checking sessions. Readings stay consistent as long as the contact pressure is maintained.

Installation and Common Issues

Place the battery between the two contact points; the 11 cm x 6 cm x 2.5 cm body fits easily in a drawer or tool pouch. If the needle does not move, verify that both terminals touch the contacts before deciding the cell is dead. The unit weighs 51 g and requires no setup beyond correct battery orientation.

Questions about this item

Does the tester itself need a battery to operate all day?

The unit is not battery powered, so it draws no power of its own while you check cells continuously.

What battery types must I already have on hand for the tester to be useful?

It reads 1.5 V cells — AAA, AA, C, D — plus 9 V PP3 types and lithium sizes 10440, 14500, 16340, 18650.

Will it still give a clear reading on the older zinc-carbon AA and C cells I keep in a drawer?

Yes, the analog needle shows red, yellow or green for those standard 1.5 V sizes just as it does for alkaline cells.
