INDUSTRIAL BATTERY SEBL SERIES

Product catalog summary

Overview
This document outlines the technical specifications and operational guidelines for the SEBL Pocket Plate Range of sealed Nickel-Cadmium (NiCd) batteries. These batteries are designed for low maintenance and high reliability, suitable for applications in electric power, telecommunications, and transportation.

Key Features

Low Maintenance: Features valve-regulated vent plug technology, reducing water consumption and allowing a top-up interval of 3-5 years.
High Reliability: Incorporates pocket type plates and high-strength pasted plates within a semi-transparent, impact-resistant container.
High Performance: Operates efficiently in temperatures from -50°C to 70°C, with a service life exceeding 20 years under recommended conditions.

Applications
These batteries are ideal for standby power supplies, starting power supplies for diesel engines, and direct power supplies for transportation tools. They include a valve-regulated vent plug for pressure regulation and fire prevention.

Charging Recommendations

Constant Voltage Mode: Suitable for continuous parallel operation with specific float and boost voltage ranges for different battery types (SEBL, SEBM, SEBH).
Constant Current Mode: Normal charging at 0.2 C5 A for 8 hours, with quick charging options available.

Electrical Specifications & Dimensions
Detailed tables provide information on nominal voltage, capacity, dimensions, weight, and terminal specifications for various SEBL models, ranging from 10Ah to 1200Ah.

Discharge Data
Discharge performance data is provided for various SEBL models, detailing available amperes at different temperatures and final voltages, in accordance with IEC60623 standards.

Specifications
Detailed discharge performance data is presented for SEBL series batteries, with capacities ranging from 700 to 1200 Ah. Data is provided for different time intervals at a final voltage of 1.00 V/cell and a temperature of +20°C ±5°C.

Procedures
The document outlines methods for calculating battery capacity, considering parameters like nominal voltage, load current, backup time, and temperature range. An example calculation is provided for an inverter load of 50KVA with a backup time of 30 minutes, selecting SEBL300 cells.

Standards
The discharge performance data adheres to the IEC60623 standard, ensuring consistent and reliable battery performance.

Recommendations
For float voltage operation, a float voltage between 1.40-1.48 volts per cell is recommended, with an example suggesting 1.44 VPC for optimal performance.

Data Interpretation
Tables and graphs illustrate discharge curves and temperature effects on the SEBL series, aiding in understanding battery performance under various conditions.

Critical Information
- The number of cells required is calculated based on the system's nominal voltage divided by the nominal voltage of a cell (1.2 Volts).
- Selecting a battery with a capacity equal to or above the calculated maximum battery current is crucial to meet backup time requirements.

Conclusion
This document serves as a comprehensive guide for selecting and calculating the appropriate NiCd battery capacity for specific applications, ensuring reliable performance and adherence to industry standards.
