LIR2032H Rechargeable Li-ion Battery 3.7 V

LIR2032 Rechargeable Li-ion Battery 3.7V

Technical Specifications:

Type: Rechargeable Lithium-ion (Li-ion) coin cell.

Model: LIR2032H.

Nominal Voltage: 3.7 V (reaches 4.2 V when fully charged).

Capacity: Typically 70 mAh

Discharge Current (H-version): Features lower internal resistance, allowing it to deliver higher current than standard LIR2032 without overheating or capacity loss.

Cycle Life: Up to 500+ cycles (with proper maintenance).

Dimensions: Diameter 20 mm, Height 3.2 mm.

Weight: Approx. 3 g.

Key Advantages:

High Discharge Power: Ideal for wireless communication modules (Bluetooth, Zigbee) that consume short but strong current pulses during transmission.

Cost-Effective: Replaces disposable CR2032 batteries in devices with a charging circuit, reducing environmental waste.

Voltage Stability: The "H" series maintains voltage better under heavy loads, ensuring electronics do not shut down prematurely.

Applications:

Smart Devices: Wearable sensors, active RFID tags.

Security Systems: Alarm fobs, smart locks.

Medical Equipment: Compact diagnostic devices.

LED Lighting: Powerful mini flashlights or decorative lighting.
