• Purpose: Extends UPS backup runtime during power outages

• Rackmount Design: Fits standard 19‑inch rack enclosure, making it easy to install alongside the UPS

• Safety Features: Includes protection against:

  • Overcharge

  • Short circuit

  • Deep discharge

• Scalability: Multiple battery banks can be connected (where supported) to increase backup duration

• Typical Applications: Data centers, network/server rooms, telecom equipment, critical infrastructure where extended runtime is needed

⚠️ Exact values for battery voltage (VDC), capacity (Ah), runtime at given load, physical dimensions, and weight are not publicly listed on the main product page I could find. If you can provide those details (e.g., load size or required runtime), I can help estimate backup duration or locate a detailed spec sheet/manual that includes numeric figures.

Features

1. Model‑Specific Design

This battery bank is specifically engineered to work with the K‑Star UDC9110‑RT UPS, meaning its electrical characteristics (voltage, connectors, and charging profile) match that UPS model. Because it’s purpose‑built rather than generic, you get reliable performance, proper communication between the UPS and battery bank, and reduced risk of damage.

2. Extended Backup Time

The primary function of this battery bank is to provide additional runtime during power outages. Without it, the UPS uses only its internal batteries and might keep your equipment running for a short time. With the external bank connected, your UPS gains a much larger reserve of stored energy — ideal for longer outages or higher power loads.

3. Rackmountable Unit

The unit is designed to fit into a standard 19‑inch server rack, just like your UPS. This rackmount form factor keeps your setup neat, secure, and easy to integrate with existing IT infrastructure. Proper rack mounting also improves cooling and space efficiency.

4. Sealed Lead‑Acid Battery Technology

Inside the battery bank are sealed lead‑acid (VRLA) batteries — a mature, reliable battery technology used widely in UPS systems. They are maintenance‑free (you don’t need to add water), safe for indoor environments, and can provide consistent backup power. These batteries also perform well over many charge/discharge cycles when properly maintained.

5. Built‑In Safety Protections

The battery bank includes essential safety features such as:

• Overcharge protection — prevents damage from excessive charging.

• Short‑circuit protection — stops dangerous current spikes.

• Deep‑discharge protection — preserves battery health by avoiding excessive drain.

These protections help ensure the battery bank operates safely and lasts as long as possible.

6. Scalability

If your power backup needs grow over time, you can connect multiple external battery banks in sequence (as supported by the UPS) to increase backup time even further. This makes the system flexible and expandable — ideal for evolving IT environments.

7. Seamless Integration

Unlike generic battery packs, this external bank is designed to integrate smoothly with the UPS system. That means setup is simpler, communications between UPS and batteries are correct, and the UPS can manage charging and discharge more effectively.

8. Ideal for Critical Applications

While not a “feature” in the strictest sense, this external battery bank is specifically targeted at data centers, corporate IT departments, network operations, and telecom systems where continuous uptime is critical. Its design reflects the reliability, space efficiency, and scalability required in these environments.

Benefits

• 📈 Longer Power Backup: Ensures critical systems such as servers, networking gear, and communications equipment stay powered during extended outages.

• 💾 Data & Operations Protection: Reduces risk of data corruption, interruptions, and costly downtime in business environments.

• 🎯 Cost‑Effective Power Expansion: Offers an economical way to extend UPS runtime without needing a larger UPS unit.

• 🔄 Seamless Integration: Designed to work directly with your existing UPS setup without the need for complicated adapters or third‑party modifications.

Ideal Use Cases

This external battery bank is best suited for:

• Enterprise IT departments and data centers

• Telecommunications hubs

• Corporate server rooms and network operations

• Any environment where uninterrupted power is critical for business continuity

Tips for Best Performance

• Pair the battery bank only with your compatible UPS (UDC9110‑RT) for reliable operation.

• Ensure good rack airflow and cooling to maximize battery life and performance.

• Conduct regular battery health checks to maintain consistent backup performance.

• Expand with extra battery banks if your setup demands longer run times.
