🔧 What it does & how to use

This little tester is designed for watchmakers, repairers and hobbyists who need a fast way to check whether a button cell battery is still good before fitting it, or to confirm a customer's dead battery needs replacing. No setup or calibration required — just place the cell on the contacts and read the needle.

• Position the battery: Sit the button cell onto the tester's contact points, matching polarity.
• Read the needle: Watch the gauge swing across the dial.
• Green: Needle rests in the green zone — the cell has good charge and is fine to use.
• Replace zone: Needle swings towards the replace marking — little to no charge left, fit a new battery.
• Repeat: Test as many cells as needed, one at a time, for quick sorting during repairs.
