VOLTCRAFT LIR2450 Rechargeable Lithium-Ion Button Cell Battery, 3.6 V, 120 mAh, 100-Pack VC-18689120

Imagine a busy watchmaker's workshop, where dozens of timepieces await fresh power. Instead of reaching for disposable CR2450 cells, the technician pops a VOLTCRAFT LIR2450 rechargeable button cell into each watch, knowing it can be recharged up to 500 times. This 100-pack ensures the workshop stays stocked for months, reducing waste and cutting costs.

Why choose it

These LIR2450 cells are direct replacements for CR2450 non-rechargeable batteries, but with the added benefit of reusability. With up to 500 charge/discharge cycles, you save money and reduce environmental impact. The lithium-ion chemistry provides a stable 3.6 V output, ideal for devices that need consistent power. The flat top design ensures compatibility with a wide range of battery holders.

Ideal use cases

• Watches and clocks
• Calculators and small electronics
• Remote controls
• Medical devices (e.g., glucose meters, thermometers)
• IoT sensors and smart home devices
• Backup power for memory and RTC modules

Good to know

While these batteries are rechargeable, they require a compatible Li-ion charger designed for 3.6 V button cells. Do not attempt to charge them in a standard NiMH or NiCd charger. For best longevity, avoid deep discharges and store in a cool, dry place when not in use. Always verify device compatibility before use, as the higher voltage (3.6 V vs 3.0 V for CR2450) may not be suitable for all applications.
