Colour/Type: Digital cell battery tester
🔧 What it does & how to use
This handy digital tester is built for watchmakers and hobbyists who need a fast, reliable way to check button-cell (coin cell) batteries before fitting them into a watch or small device. Rather than guessing whether a battery is good, dead, or on its way out, the digital display gives you an instant voltage reading so you can test stock before use or diagnose a watch that's stopped running.
- Charge it: plug in the supplied Micro USB cable to power up the tester's digital display.
- Position the battery: place the button cell between the two probes, matching positive and negative terminals.
- Read the display: the screen shows the battery's voltage, letting you judge at a glance whether it's fresh, weak, or flat.
- Test before fitting: use it to check new stock batteries or to rule out a bad battery when troubleshooting a watch repair.
