Rongon Button Cell Tester

The Rongon Button Cell Battery Tester is a portable voltmeter designed for 1.55V and 3V button cells. It suits watchmakers, repair technicians and hobbyists who need a quick health check on coin-type batteries. The pocket-sized plastic body makes it a convenient addition to a tool kit or workbench.

Simple Press Operation

Place the battery with its positive pole facing up and press down firmly to engage the contacts and display the charge state. The tester indicates whether the cell is good, weak or poor without any leads or settings to configure. Poor contact pressure is the most common reason for a false low reading.

Consistent Readings Under Repeated Use

The analogue pointer mechanism delivers the same voltage indication each time a cell is tested, so results remain stable across multiple checks in a session. No internal battery is required, so the tool does not drift as its own power source ages. It is not suited for cylindrical cells such as AA or AAA, nor for loads that demand a sustained current draw test.

Questions about this item

How can I confirm the tester is reading correctly after I press a battery into it?

The pointer or LCD rating bar will move to show poor, weak, or good voltage for the 1.55 V or 3 V cell you are testing.

What comes in the box and do I need any extra parts to start testing?

One handheld tester is included; it is battery powered and needs no separate leads or adapters for button cells.

Which version should I choose if I only test 1.55 V and 3 V watch batteries?

This model is built specifically for 1.55 V and 3 V button cells, so it covers those two voltages without needing a multi-size unit.
