SubC cell battery 1.2V 3000mAh vacumme cleaner power tools battery

Features

1. High Discharge Rate Capability: Designed to deliver high continuous (15C) and peak pulse (20C) discharge currents, making it suitable for demanding applications like power tools.

2. Robust Cycle Life: Can withstand over 500 charge-discharge cycles while maintaining more than 80% of its initial capacity, ensuring longevity and value.

3. Low Internal Resistance: Very low internal resistance (<8mΩ) enables high current delivery with minimal voltage drop and heat generation.

4. Wide Operating Temperature Range: Can operate effectively in a broad range of environments, from -20°C to +50°C.

5. Environmentally Friendly: Contains no heavy metals like cadmium or lead, making it a more environmentally conscious choice.

Applications

• Power Tools: Drills, saws, impact wrenches, and other cordless tools.

• Remote Control (RC) Hobbies: High-performance RC cars, boats, and aircraft.

• Professional Lighting: Portable spotlights and emergency lighting.

• Medical Devices: Certain portable medical equipment.

• Backup Power: Uninterruptible power supplies (UPS) for specific applications.

Warnings & Precautions

Charging

• Use a NiMH-Specific Charger: Always use a charger designed for NiMH chemistry.

• Avoid Overcharging: Do not exceed the recommended charge times (e.g., 15 hours for 0.1C charge). Modern smart chargers with negative delta voltage (-ΔV) detection are preferred to terminate charge automatically.

• Temperature Monitoring: Charge only within the specified temperature range (0°C to +45°C). Charging outside this range, especially below 0°C, 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 Deep Discharge: While more tolerant than some chemistries, repeatedly discharging the battery to very low voltages (below 1.0V per cell) can shorten its lifespan.

• Temperature Management: Avoid discharging outside the recommended temperature range (-20°C to +50°C). Extreme cold reduces performance; extreme heat accelerates aging.

• Prevent Short Circuits: Short circuits can cause very high currents, leading to extreme overheating, terminal damage, or fire. Insulate terminals when not in use or during transport.

Storage

• Partial Charge Storage: For long-term storage, it is recommended to store the battery at a partial state of charge (around 40-60%). Storing the battery for extended periods while fully charged or fully discharged can lead to capacity degradation.

• Cool and Dry Environment: Store in a cool, dry place away from direct sunlight and heat sources. The ideal long-term (1 year) storage temperature is between -20°C to +25°C.

• Regular Checks: If stored for very long periods, check the voltage periodically and recharge if it drops significantly to prevent over-discharge.
