Ni-Cd battery SEBH series

Ni-Cd battery SEBH series

Product catalog summary

Overview: The SEBH Pocket Plate Range by EverExceed Corporation features sealed Nickel-Cadmium (NiCd) batteries with capacities from 10 to 500Ah, designed for reliability and low maintenance in industrial applications.

Specifications: These batteries operate efficiently between -40°C and +60°C, with short-term tolerance from -50°C to +70°C, and are designed to last over 20 years with minimal maintenance due to robust construction and a large electrolyte reserve.

Performance: NiCd batteries in this range can withstand deep discharges, recharge quickly, and are cost-efficient with no downtime or replacement costs. They are easy to install and store.

Reliability: The batteries are reliable in both controlled and harsh environments, resistant to electrical abuse and mechanical stress, with an electrolyte solution that maintains optimal performance.

Standards and Certifications: Manufactured to ISO 9001 standards, these batteries comply with EN-50272-2 safety requirements and support full recycling services.

Applications: Ideal for high discharge rate applications such as switchgear tripping, diesel engine starting, and UPS systems, these batteries tolerate electrical and mechanical abuse well.

Charging Recommendations: Constant voltage charging is recommended, with specific voltage ranges for different battery types (SEBL, SEBM, SEBH), and they can also be charged in constant current mode.

Dimensions and Weights: Detailed specifications for each battery type include dimensions, weight, and terminal types.

Discharge Data: Discharge performance data is provided for various capacities and conditions, ensuring users can select the appropriate battery for their needs.

Calculation Methods: Battery capacity calculations require nominal voltage, load current, backup time, voltage range, temperature, layout, and physical condition. Float voltage operation is crucial, with common float voltages from 1.40 to 1.48 volts per cell.

Example Calculation: An example calculation for maintaining an inverter load of 50KVA at 0.8 power factor for 30 minutes at 20~25°C results in selecting the SEBH300 cell type.

System Voltage and Number of Cells: The number of cells is determined by dividing the nominal system voltage by the nominal cell voltage (1.2 Volts), with a table showing configurations.

Temperature Effect Curves: Graphs illustrate how temperature affects voltage and capacity percentage, showing performance variations with temperature changes.
