Description
This 18650 Lithium-Ion Rechargeable Battery offers a nominal capacity of 2000mAh and operates at a nominal voltage of 3.7V, making it suitable for a wide range of portable electronic devices and DIY power projects. It supports a maximum continuous discharge current of 2C and features built-in safety mechanisms including CID (Current Interrupt Device) and PTC (Positive Temperature Coefficient) protection for enhanced reliability and safe operation under various conditions
Key Features
- Nominal Capacity: 2000mAh; suitable for moderate to high-drain applications
- Nominal Voltage: 3.7V; compatible with standard 18650 applications
- Maximum Discharge Current: 2C (up to 4A); supports moderate to high current draw
- Safety Protection: Equipped with CID (Current Interrupt Device) and PTC (Positive Temperature Coefficient); the PTC acts as a resettable fuse under overcurrent or overheating conditions, while the CID permanently disconnects the cell under overpressure conditions to prevent catastrophic failure
- Terminal Configuration: Available with button top (5-in-1 combined terminals) as specified
- Low Internal Resistance: Range of 25–48mΩ depending on variant, ensuring efficient power delivery
- International Safety Certifications: Compliant with CB, ROHS, BIS, IEC, KC, TUV, UN38.3, ISO, and CQC standards
- Long Cycle Life: Delivers 300–500 cycles at 0.5C charge/discharge with ≥80% capacity retention (depending on specific model variant)
