• Memory backup modules and CMOS batteries in small devices
• Small sensors, LED indicators, and medical measuring devices with low current consumption

Key specifications

• Nominal voltage: 3 V
• Chemistry: Lithium manganese dioxide (Li-MnO2) coin cell
• Diameter and height: standard 24.5 mm diameter / 3.0 mm height form factor
• Typical capacity: suitable for low-drain applications (capacity varies with load and temperature)
• Operating temperature range: suitable for typical consumer device environments

How to use

Install the Panasonic CR2430 with correct polarity, ensuring the positive (+) side faces the contact indicated in the device battery compartment. Handle the cell carefully to avoid shorting the terminals and use appropriate tools or non-metallic tweezers if needed. Replace only with the same size and voltage coin cell to maintain proper device operation. Dispose of used lithium coin cells according to local battery recycling and hazardous-waste regulations.

Usage recommendations

Store unused batteries in a cool, dry place away from direct heat and sunlight. Avoid mixing new and used batteries or different chemistries in the same device. Check device manufacturer guidance for recommended replacement intervals and follow local disposal rules for lithium batteries.
