Product Description
D5500mAh 1.2V rechargeable Nicd Nickle Cadmium Battery For Power Tools Lighting
Features
- High Capacity & Energy: Offers a high capacity of 5500mAh (5.5Ah) for extended runtime in demanding applications.
-
Excellent High-Rate Discharge Performance: Very low internal resistance allows for high discharge currents, making it ideal for power tools and other high-drain devices.
-
Long Cycle Life: Can withstand over 500 charge-discharge cycles and can exceed 1000 cycles with proper maintenance, offering good economic value.
-
Robust and Durable: Built with a metal container, making it mechanically sturdy and sealed to prevent electrolyte leakage.
-
Wide Operating Temperature Range: Can operate effectively in a broad range of environments, from -20°C to +60°C or even -30°C to +50°C.
-
Overcharge and Overdischarge Tolerance: More resistant to damage from overcharging and deep discharging compared to some other chemistries .
- Good Shelf Life: Low self-discharge compared to some alternatives (10-20% per month ), and can be stored for long periods without significant performance degradation if stored properly .

Warnings & Precautions
- Use a NiCd-Specific Charger: Always use a charger designed for NiCd chemistry. Using an incompatible charger can be dangerous .
- Avoid Overcharging: While tolerant, excessive overcharging can damage the battery.
- Temperature Monitoring: Charge only within the specified temperature range (0°C to +45°C is common ; 10°C-30°C is ideal ).
- Charge in a Well-Ventilated Area: Provide adequate space around the charger and battery during charging.
Discharging
- Mitigating Memory Effect: To minimize memory effect:
-
- For devices with deep cycles: Ideally, fully discharge the battery (to ~1.0V per cell) before each recharge .
-
- For applications with partial cycles: Every 10-15 cycles, perform a full discharge followed by a full charge .
- Avoid Excessive Deep Discharge: While periodic full discharge helps with memory effect, repeatedly discharging far below 1.0V per cell can be harmful. Avoid leaving tools or devices with dead batteries switched on for extended periods.
- Temperature Management: Avoid discharging outside the recommended temperature range (-20°C to +60°C ). Extreme cold reduces performance; extreme heat accelerates aging.
- Partial Charge Storage: For long-term storage (longer than a few months), it is often recommended to store the battery in a fully discharged state (or near 0V) as this can allow for easier capacity recovery later .
- 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 or below 35°C for long periods .
- Recovery after Storage: After prolonged storage, the battery may require a few charge/discharge cycles to regain its full capacity.
