The cells are engineered for compatibility with a variety of coin-cell slots and for ease of installation in compact housings.

Suitable for

• Watches and timers
• Calculators and small electronic instruments
• Remote controls and key fobs
• Medical sensors and low-power monitoring devices

Key specifications

• Form factor: button/coin (flat) cell with 40 mm diameter
• Quantity: set of 4 cells (mixed)
• Intended use: low-drain and intermittent-use electronic devices
• Expected characteristics: compact size and stable voltage output suitable for small devices

How to use

Turn off the device before replacing the battery. Remove the old cell carefully using a non-conductive tool if possible, taking note of polarity markings. Insert the new 40 mm button cell matching the device's polarity orientation and secure any compartments or covers. After replacement, check device operation to confirm proper seating and electrical contact.

Usage recommendations

Store unused cells in a cool, dry place away from metal objects to prevent shorting. Dispose of used cells according to local regulations for battery recycling. Keep out of reach of children and do not attempt to recharge non-rechargeable button cells.
