SC Size 1.2V Cylindrical Nicd Battery Packs 2000mAh for R/C Hobbies

Features

1. High-Rate Discharge Performance: Excellent high-current discharge capability, supporting up to 10C continuous discharge (20A) , making it ideal for high-drain applications like R/C hobbies.

2. Long Cycle Life: Can withstand over 500 charge-discharge cycles  while maintaining more than 80% of its initial capacity, offering good durability.

3. Rapid Charging: Supports fast charging at rates up to 0.5C (1000mA) with appropriate chargers featuring proper termination methods (-ΔV) .

4. Wide Operating Temperature Range: Can operate effectively in a broad range of environments, from -20°C to +60°C , performing well where other battery types might fail.

5. Robust and Durable: Built with a metal container, making it mechanically sturdy and sealed to prevent electrolyte leakage.

6. Overcharge and Overdischarge Tolerance: More resistant to damage from overcharging and deep discharging compared to some other chemistries.

Specification

 Applications

• R/C Hobbies: High-performance remote-control (RC) cars, boats, aircraft, and drones .

• Power Tools: Drills, saws, and other cordless tools requiring high burst currents .

• Toys and Hobbies: Electric toys .

• Backup Power: Uninterruptible Power Supplies (UPS) .

Warnings & Precautions

Charging

• Use a NiCd-Specific Charger: Always use a charger designed for NiCd chemistry. Using an incompatible charger (e.g., for Li-ion or NiMH) is dangerous and may not terminate charging correctly .

• Avoid Overcharging: While tolerant, excessive overcharging can damage the battery. Use smart chargers with negative delta voltage (-ΔV) detection for rapid charging to terminate charge automatically .

• Temperature Monitoring: Charge only within the specified temperature range (0°C to +45°C) . Charging outside this range can lead to reduced capacity and potential damage.

• Charge in a Well-Ventilated Area: Provide adequate space around the charger and battery during charging.

Discharging

• Avoid Excessive Deep Discharge: While periodic full discharge helps with memory effect, repeatedly discharging far below 1.0V per cell can be harmful.

• Temperature Management: Avoid discharging outside the recommended temperature range (-20°C to +60°C). Extreme cold reduces performance; extreme heat accelerates aging.

• Prevent Short Circuits: Never allow the positive (+) and negative (-) terminals to connect directly. Short circuits can cause very high currents, leading to extreme overheating, terminal damage, leakage, or fire .

Storage

• Storage State: For long-term storage (longer than a few months), it is often recommended to store the battery in a discharged state.

• Cool and Dry Environment: Store in a cool, dry place away from direct sunlight, moisture, and heat sources. The ideal storage temperature is between -20°C to +35°C .

• Recovery after Storage: After prolonged storage, the battery may require a few charge/discharge cycles to regain its full capacity.
