C&D Technologies LIBERTY® 1000 Series (LS): Reliable Power for Critical Applications
The LIBERTY® 1000 Series (LS) from C&D Technologies is a robust line of valve-regulated lead-acid (VRLA) batteries engineered for high performance and reliability in a variety of standby power applications. These batteries are a popular choice for industries that demand uninterrupted power to protect critical infrastructure.
Core Technology and Design
At the heart of the LIBERTY® 1000 Series is the use of Absorbent Glass Mat (AGM) technology. This design immobilizes the battery's electrolyte within a specialized glass mat separator, creating a spill-proof and maintenance-free battery. This construction allows for flexible installation, as the batteries can be operated in any orientation without the risk of leakage.
A key feature of the series is its 10-year design life in full float service at a controlled temperature of 25°C (77°F). This longevity is achieved through a combination of a thick radial grid design, high-purity lead-calcium alloys, and a high-impact, flame-retardant PVC container that prevents moisture loss and oxygen ingress.
Key Specifications and Features
The LIBERTY® 1000 Series is available in a range of models with varying voltage and capacity ratings to suit different load requirements. Common models include:
- LS 12-100: 12-volt, 100 Ampere-hour (Ah) at the 8-hour rate
- LS 6-200: 6-volt, 200 Ah at the 8-hour rate
- LS 4-300: 4-volt, 300 Ah at the 8-hour rate
- LS 2-600: 2-volt, 600 Ah at the 8-hour rate
Notable features across the series include:
- High-Rate Discharge: Optimized for applications requiring significant power for short durations, such as in UPS systems.
