How to use

Before installation, verify device compatibility with the CR2016 cell size and 3V nominal voltage. Remove the discharged cell from the device following the manufacturer’s instructions, noting polarity orientation. Insert the Duracell DL2016 with the positive (+) side facing the indicated direction and ensure it is seated securely in the battery compartment or contact clip. After replacement, test the device to confirm correct operation and dispose of the old battery according to local regulations for lithium cells.

Usage recommendations

Store unused batteries in a cool, dry place at moderate room temperature and avoid prolonged exposure to heat or direct sunlight. Do not attempt to recharge, open, heat above specified temperatures, or incinerate the cell. Keep out of reach of children and follow device manufacturer guidance for battery replacement and disposal.
