Special front access design for telecom cabinets
Valve regulated lead acid (VRLA) technology
High-compression Absorbed Glass Mat (AGM) materials
Proprietary Fixed Orifice Plate Pasting technology
Triple stage unique terminal sealing design
Heavy-duty copper plated terminals
Flame-retardant reinforced ABS case option
Flame arresting, low-pressure safety release venting system

Standards and Compliance
The batteries comply with ISO 9001, ISO 14001, IEC 60896-21/22, BS 6290 PART 4, NEBS Compliant, and Bellcore TR-NWT-000766.

Construction and Safety
Constructed with lead-calcium-tin alloy plates and high purity lead, the batteries minimize impurities and feature a microporous glass fiber separator and a safety release valve for pressure management, ensuring maintenance-free operation.

Transport and Handling
Classified as non-hazardous for surface, marine, and air transport, complying with relevant regulations.

Electrical Specifications
Includes detailed tables of electrical specifications such as nominal voltage, capacity, short circuit current, internal resistance, and dimensions for various battery models.

Performance Data
Discharge ampere hours data is provided for different battery models, showing performance at various discharge times and voltages.

Discharge Data
Presented in Amps and Watts per Cell (WPC), with specific discharge values at different VPC levels for each battery model.

Charging Recommendations
Recommended float voltage is 2.27 VPC at 20°C, with a range of 2.25 VPC to 2.30 VPC. An equalize voltage of 2.35 VPC is suggested for 12 hours. Temperature compensation requires adjustments of 3 mV/°C/cell above and below 25°C.

Temperature and Capacity
Graphs show the relationship between extracted capacity and temperature, as well as self-discharge rates in relation to storage temperature, aiding in understanding temperature effects on performance and longevity.

Cycle Life
Depicts the number of cycles at different levels of capacity withdrawal (e.g., 80%, 50%, 25%, 10%), vital for estimating lifespan under various usage conditions.

Conclusion
The document serves as a comprehensive guide for understanding the performance, charging, and maintenance of the Front Access FT AGM Range VRLA batteries, emphasizing adherence to specified charging voltages and temperature compensations for optimal performance and longevity.
