How to use

Identify the battery compartment and confirm the device specifies the CR1620 size and 3V nominal voltage before installation. Remove the depleted cell following the device manufacturer’s instructions, taking care to note polarity markings. Insert the new Hedo CR1620 cell with correct polarity, ensuring the cell seats properly in the holder, then close the compartment and test the device. Dispose of used lithium cells according to local regulations for battery recycling or hazardous waste.

Usage recommendations

Store unused cells in a cool, dry place away from direct sunlight and heat sources. Avoid short-circuiting cells by keeping them in original packaging until use. For devices with continuous monitoring or medical functions, replace batteries proactively according to the device manufacturer's guidance to ensure uninterrupted operation.
