How to use

To replace the battery, open the device's battery compartment following the manufacturer's instructions, taking care to avoid shorting the terminals. Note the correct polarity before removing the old cell and insert the new Varta SR44 with the correct orientation. Ensure the compartment is clean and free of corrosion before closing. Dispose of the spent battery according to local regulations for household batteries; do not attempt to recharge this primary cell.

Usage recommendations

Use the Varta SR44 in devices that specify SR44 / 303-sized alkaline button cells and observe polarity when installing. Store unused cells in a cool, dry place away from metal objects to prevent accidental short circuits. Replace batteries promptly when device performance degrades to avoid leakage-related damage.
