AA2000 Nimh Battery Packs 7.2V For Alarm System

Features

1. High Reliability: Designed for continuous, long-term service in critical applications like alarm systems, offering stable performance.

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

3. Wide Operating Temperature Range: Functions effectively in a range of -20°C to +60°C, making it suitable for various environmental conditions where alarm systems might be installed.

4. Low Self-Discharge: Retains charge for extended periods, crucial for standby applications where the battery may need to hold a charge for weeks or months before being called upon.

5. Maintenance-Free Operation: NiMH chemistry requires minimal maintenance compared to vented lead-acid or NiCd batteries, ideal for sealed alarm system units.

6. Environmentally Friendly: Contains no toxic heavy metals like cadmium or lead, making it a more environmentally conscious choice and often compliant with RoHS directives.

7. Good High-Rate Discharge Capability: Supports moderate discharge currents suitable for powering alarm sirens, sensors, and communication modules.

Specifications

Applications

• Alarm Systems: Intrusion alarms, fire alarm systems, emergency lighting in alarm panels.

• Security Devices: Access control systems, security sensors and cameras, electronic locks.

• Emergency Backup: Uninterruptible Power Supplies (UPS) for low-power critical devices, emergency communication systems.

• Other Low-Power Standby Applications: Various devices requiring reliable backup power.

Warnings & Precautions

Charging

• Use a NiMH-Specific Charger: Always use a charger designed for NiMH chemistry and configured for this battery's voltage (7.2V-9V) 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.

• 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.

Discharging

• Avoid Deep Discharge: Stop using the battery before reaching the cut-off voltage (6.0V for the pack). Over-discharging can cause irreversible internal damage and shorten its lifespan.

• Temperature Management: Avoid discharging outside the recommended temperature range (-20°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 storage temperature is between -20°C to +35°C.

• Regular Checks (for Standby): Even though self-discharge is low, for critical alarm applications, consider implementing periodic (e.g., annual) capacity checks or refresher cycles as part of system maintenance to ensure reliability.
