High Voltage Nimh Battery Packs 12V SC3300mAh Nimh Battery Packs plastic housing for sweeper

Features

1. High Energy Density: Offers a capacity of 3300mAh, providing substantial runtime for powered devices like sweepers.

2. High Discharge Capability: Supports high continuous discharge currents (up to 10C or 33A), making it suitable for demanding applications like motor-driven sweepers.

3. Plastic Housing (PVC): The PVC outer shell provides insulation, protection against minor impacts, and helps contain potential leakage, enhancing safety and durability.

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

5. Wide Operating Temperature Range: Can operate effectively in a range of environments, from -10°C to +60°C during discharge.

6. Environmentally Friendly: NiMH chemistry contains no toxic heavy metals like cadmium or lead, making it a more environmentally conscious choice compared to NiCd batteries.

Specifications

Applications

• Sweepers/Cleaners: Primary power source for electric sweepers, scrubbers, and other cleaning machines.

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

• Toys and Hobbies: High-performance remote-control (RC) toys, electric toys.

• Emergency Lighting: Exit signs, emergency luminaires.

• Medical Devices: Portable medical equipment.

• Backup Power: Uninterruptible Power Supplies (UPS).

Warnings & Precautions

Charging

• Use a NiMH-Specific Charger: Always use a charger designed for NiMH chemistry and configured for this battery's voltage (15V) and current limits.

• Avoid Overcharging: Do not exceed the recommended charge times. While NiMH batteries are somewhat tolerant, excessive overcharging can damage them.

• 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 Deep Discharge: Stop using the battery before reaching the cut-off voltage (10.0V for the pack). Over-discharging can cause irreversible internal damage and shorten its lifespan.

• Temperature Management: Avoid discharging outside the recommended temperature range (-10°C to +60°C). Extreme cold reduces performance and capacity; 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

• Partial Charge Storage: For long-term storage (longer than a few months), it is recommended to store the battery at a partial state of charge (around 40-60%).

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

• Regular Checks: If stored for extended periods, check the voltage periodically (every 2-3 months) and recharge if it drops significantly to prevent over-discharge.
