Advantages of Li-ion Rechargeable vs CR Primary

• Rechargeable: Can be recharged 300-500 times vs single-use CR batteries
• Cost-Effective: Saves money over time despite higher initial cost
• Environmentally Friendly: Reduces battery waste
• Higher Voltage: 3.6V nominal vs 3.0V for CR batteries
• Stable Voltage: Maintains voltage better throughout discharge
• No Memory Effect: Can be recharged at any time

Important Voltage Compatibility Note

⚠️ VOLTAGE DIFFERENCE: LIR batteries are 3.6V nominal (4.2V fully charged) while CR batteries are 3.0V. Ensure your device can handle the higher voltage before replacing CR batteries with LIR batteries. Most modern devices are compatible, but always check device specifications first.

Choosing the Right Model

Choose LIR2430 if you need:

• Thinnest profile (3.0mm height)
• Replacement for CR2430
• Compact devices with limited space
• Lower capacity needs (~60mAh)

Choose LIR2450 if you need:

• Medium capacity (~120mAh)
• Replacement for CR2450
• Good balance of size and capacity
• Most common rechargeable coin cell size

Choose LIR2477 if you need:

• Maximum capacity (~180mAh)
• Replacement for CR2477
• Longest runtime between charges
• Higher power consumption devices

Configuration Selection:

• Naked: Choose for battery holders, sockets, or direct replacement in devices
• With 3P Tabs: Choose for PCB soldering, permanent installation, or enhanced stability

Installation Guidelines

For Naked Batteries:

• Use appropriate battery holder or socket
• Ensure correct polarity orientation (+ side is larger, flat surface)
• Verify device can handle 3.6V voltage
• Test device operation after installation

For 3P Tab Batteries (Soldering):

• Use low-temperature soldering (max 260°C)
• Solder quickly (less than 3 seconds per joint)
• Avoid overheating the battery
• Ensure proper polarity
• Third tab typically for mechanical stability
• Inspect solder joints for quality

Charging:

• Use Li-ion compatible charger (4.2V charge voltage)
• Do not use standard CR battery chargers
• Charge at 0.5C rate or lower for best life
• Do not overcharge beyond 4.2V
