• Capacity: 600 VAh (equivalent to 5 years of standby life under typical load conditions).
• Dimensions: Height 76 mm, Width 203 mm, Depth 584 mm; packaged as 228 × 393 × 761 mm.
• Weight: 22.3 kg (cartridge), 25.2 kg including packaging.
• Operating Temperature: 0 °C to 40 °C – suitable for most indoor environments.
• Storage Temperature: –15 °C to 45 °C – ensures longevity when not in use.
• Humidity Range: 0 %–95 % RH (both storage and operation) – robust against moisture variations.
• Altitude: Operable up to 3,000 m; non‑operational up to 15,000 m – ideal for high‑altitude installations.
• RoHS Compliant: Yes – free from hazardous substances such as lead, mercury, cadmium, and hexavalent chromium.

Design Features & Advantages

The cartridge’s sealed construction prevents leakage of acid or electrolyte, making it safe for use in any environment. Its hot‑swap capability allows technicians to replace the battery without shutting down the UPS, ensuring continuous protection for servers, networking gear, and other mission‑critical equipment.

• Maintenance‑Free: No need for periodic electrolyte checks or water additions.
• Leak‑Proof Packaging: Reduces risk of corrosion to surrounding components.
• Compact Footprint: Fits seamlessly into the rear compartment of APC UPS units, maximizing rack space.
• Long Shelf Life: Designed for up to five years of standby performance when stored within specified conditions.
• Environmental Responsibility: RoHS certification ensures compliance with global environmental regulations.

Compatibility & Installation

This cartridge is engineered specifically for APC Smart‑UPS models that support the #118 battery size. It can be installed in both rack and tower configurations, providing flexibility across data centers, server rooms, and office environments.

1. Power Off: Shut down the UPS following manufacturer guidelines to avoid electrical shock.
2. Access Battery Compartment: Open the rear panel; remove any existing battery if present.
3. Insert Cartridge: Align the contacts and slide the cartridge into place until it clicks securely.
4. Reconnect Power: Restore UPS power and allow the unit to perform its self‑diagnosis routine.
5. Verify Status: Check the UPS interface or management software for a healthy battery indicator.

Operational Considerations

For optimal performance, keep the UPS in an environment that stays within the specified temperature and humidity ranges. Avoid exposing the unit to extreme temperatures or direct sunlight for prolonged periods. Regularly monitor the UPS status via its management interface; most APC models provide battery health metrics such as charge level, cycle count, and estimated runtime.

Environmental & Sustainability Highlights

The cartridge’s RoHS compliance means it contains no restricted hazardous substances, reducing environmental impact during disposal. Additionally, the sealed lead‑acid chemistry offers a high energy density while maintaining safety standards, making it an eco‑friendly choice for long‑term backup solutions.

Applications & Use Cases

• Data Centers: Provides uninterrupted power to servers and storage arrays during grid failures.
• Telecommunications: Keeps switching equipment operational, preventing call drops.
• Medical Facilities: Ensures life‑supporting devices remain powered during emergencies.
• Industrial Control Systems: Maintains PLCs and SCADA systems in critical manufacturing processes.

Maintenance & Lifecycle Management

While the cartridge is designed for minimal upkeep, periodic checks are recommended to confirm that contacts remain clean and free of corrosion. Replace the battery after five years or when performance metrics indicate a significant drop in capacity. Proper disposal should follow local regulations for lead‑acid batteries.

Conclusion

The APC Sealed Lead Acid UPS Battery Cartridge 118 delivers dependable, maintenance‑free backup power with a robust design that supports hot swapping and long shelf life. Its compliance with RoHS standards and suitability for high‑altitude environments make it an ideal choice for any organization seeking reliable protection against power interruptions.
