XHP Range

Product catalog summary

Overview: The document discusses XHP Ni-Cd batteries, emphasizing their low maintenance, high performance, and suitability for critical applications like UPS, engine starting, and emergency backup. These batteries are designed for long-term reliability and cost-effectiveness, with a lifespan exceeding 20 years and minimal maintenance needs.

Specifications: XHP batteries are constructed with a steel superstructure and polypropylene casing, containing sintered and plastic-bonded electrodes with an alkaline electrolyte. They surpass lead-acid batteries in longevity, requiring topping-up only every 10 years. They operate efficiently between -20°C and +50°C and can endure extremes from -50°C to +70°C for short durations.

Performance and Reliability: XHP batteries are dependable in various conditions, suitable for both onshore and offshore use. They resist electrical abuses such as AC ripple and overcharging, making them ideal for UPS systems. They deliver high power within a narrow voltage window and provide high currents even when partially discharged.

Charging and Maintenance: XHP batteries support various charging methods, including taper, constant current, constant voltage, and pulse. They perform satisfactorily in any state of charge. The maintenance float voltage is 1.40 ± 0.01 V, with a boost voltage range of 1.45 V ± 0.01 V.

Battery Sizing and Standards: The document provides detailed sizing information for different XHP battery types, including capacity, dimensions, and weight. XHP batteries comply with major electrical industry standards and are approved for use on ships and offshore installations. Alcad, the manufacturer, also offers recycling services for old batteries.

Data Tables: Extensive tables in the document detail the performance of various XHP battery types across different discharge rates and conditions, offering critical data for engineers to select the appropriate battery for specific applications.
