AAA800mAh Nimh Battery Packs 4.8V For Medical Device

Features

1. Medical Device Compatibility: Designed for use in medical equipment such as portable electronic thermometers, blood glucose meters, and other devices requiring reliable and stable power. Often designed with medical-grade reliability and safety in mind.

2. High Energy Density: Offers a balance of capacity (800mAh) and compact size (43.5*45.5mm), suitable for space-constrained medical devices.

3. Stable Voltage Output: Provides a relatively stable discharge voltage curve, crucial for the accurate operation of sensitive medical electronics.

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

5. Environmentally Friendly: NiMH chemistry contains no toxic heavy metals like cadmium or mercury, making it a more environmentally conscious choice and often compliant with RoHS directives.

6. Low Self-Discharge Options: NiMH variants are available, which retain charge for much longer periods during storage, ensuring the device is ready for use when needed.

7. Reliability: Designed for reliable performance, which is critical in medical applications.

Warnings & Precautions

Charging

• Use a NiMH-Specific Charger: Always use a charger designed for NiMH chemistry and configured for this battery's voltage (4.8V) and current limits.

• Avoid Overcharging: Do not exceed the recommended charge times or currents. While NiMH batteries are somewhat tolerant, excessive overcharging can damage them and lead to reduced lifespan, performance degradation, or leakage.

• Temperature Monitoring: Charge only within the specified temperature range (0°C to +45°C). Charging below 0°C can cause permanent damage; charging above 45°C increases the risk of leakage and damage.

• Avoid Trickle Charging Overuse: While trickle charging (e.g., 0.05C) can be used for maintenance after full charge, avoid prolonged trickle charging as it can harm the battery.

Discharging

• Avoid Deep Discharge: Stop using the battery before reaching the cut-off voltage (4.0V for the pack, or 1.0V per cell).

• Temperature Management: Avoid discharging outside the recommended temperature range (-20°C to +60°C).

• 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%). Storing the battery fully discharged for extended periods is detrimental.

• 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.

• Regular Refreshing: For standard NiMH batteries, consider giving them a full charge cycle every 3 to 6 months during storage to compensate for self-discharge and prevent over-discharge.
