UBANU BT-860 battery tester for household cells

The UBANU BT-860 is a compact, battery-powered voltmeter designed to check the remaining charge in common household cells. It accepts AA, AAA, C, D, 9V and 1.5V batteries using a spring-loaded testing arm. The analog pointer moves across a colour-coded scale to show capacity at a glance. No external power source is required because the unit draws energy from the battery under test.

Ideal for quick home checks.

This tester suits anyone who wants a fast, portable way to sort good cells from depleted ones in drawers or devices. It is not aimed at users who need calibrated digital readouts, data logging or the ability to test rechargeable chemistries under load. Buyers who require internal-resistance measurement or automated pass/fail limits should look at a different class of instrument.

Simple arm insertion; watch for contact pressure

Operation is straightforward: open the top arm, insert the cell so both terminals touch the contacts, and read the pointer. The most common issue is insufficient pressure on the negative end, especially with shorter AAA or 1.5V cells, which can give a false low reading. Ensuring the battery sits flat against the base and the arm closes firmly usually resolves the problem.

Questions about this item

Does the BT-860 tester need its own battery to operate?

No, the unit is powered and activated by the battery being checked, so no separate power source is required.

Will the analog pointer work correctly when I test older 1.5 V cells?

Yes, the color-coded calibration scale covers 1.5 V batteries and the pointer moves to show remaining charge.

How do I know the BT-860 is giving a reliable reading after I insert a battery?

The analog display pointer moves across the color-coded scale immediately, letting you verify the charge level at a glance.
