9.6V AA Nicd Energizer Rechargeable Batteries 700mAh For Hotel Phone , Dect Phone

Features

1. High Reliability: Ideal for critical communication devices like hotel/DECT phones, offering stable performance over 500+ cycles.

2. Wide Temperature Tolerance: Operates from -20°C to +60°C, ensuring functionality in varied environments.

3. Memory Effect Management: Requires periodic full discharges to mitigate memory effect (e.g., discharge every 10 cycles).

4. Overcharge/Overdischarge Tolerance: More resilient to abuse compared to other chemistries.

5. Low Internal Resistance: Supports moderate discharge currents for phone applications.

6. Long Shelf Life: Retains charge for months, suitable for backup use.

Specification

Applications

• Hotel Phones: Cordless desk phones and base units.

• DECT Phones: Digital Enhanced Cordless Telecommunications devices.

• Emergency Communication Devices: Backup power for critical systems.

• Consumer Electronics: Toys, solar lights, emergency lights.

Warnings & Precautions

Charging

• Use NiCd-Specific Chargers: Only use chargers designed for NiCd chemistry with voltage/current limits matching 9.6V/700mAh specs. Avoid Li-ion/NiMH chargers.

• Avoid Overcharging: While tolerant, prolonged overcharging reduces lifespan. Use smart chargers with -ΔV or temperature cutoff.

• Temperature Limits: Charge only between 0°C to +45°C. High temperatures cause leakage; low temperatures lead to incomplete charging.

Discharging

• Prevent Deep Discharge: Do not discharge below 8.0V (1.0V per cell) to avoid cell reversal and capacity loss.

• Memory Effect Mitigation: Perform full discharges (to 8.0V) every 10 cycles to minimize memory effect.

Storage & Handling

• Storage State: Store partially discharged (≈40-50% SOC) in a cool, dry place.

• Cadmium Toxicity: Do not disassemble—cadmium is toxic. Recycle at designated facilities.

• Physical Damage: Avoid crushing/puncturing cells to prevent leakage.

Safety

• Ventilation: Ensure adequate airflow during charging to dissipate gases.

• Child Safety: Keep away from children due to choking hazard and toxic materials.

• No Incineration: Cadmium vapor is toxic if burned.

Maintenance

• Cleaning: Clean terminals with isopropyl alcohol to prevent corrosion.

• Replacement: Replace pack when capacity drops below 80% (≈560mAh).

Disposal

• Recycle Only: NiCd batteries must be recycled due to toxic cadmium. Do not dispose in household waste.
