VRLA battery HR series

Product catalog summary

Overview: The document outlines the technical specifications and features of EverExceed's High Rate Range VRLA AGM batteries, which are designed for high-performance applications such as UPS, emergency lighting, and telecom systems. These batteries are noted for their high energy density, reliability, and long lifespan.

Specifications: The batteries have capacities ranging from 26Ah to 250Ah with a voltage per cell (VPC) of 1.80 at C10. They function effectively in temperatures from -40°C to +70°C, with an optimal range of +20°C to +28°C. The storage time from a fully charged state is 12 months at 20°C-25°C, with storage time halving for every 9°C increase.

Applications: Suitable for use in UPS systems, data centers, banks, hospitals, emergency response centers, and power generation plants.

Innovative Features: The batteries boast a 12-year design life at 25°C, high compression AGM technology for over 99% recombination efficiency, and proprietary fixed orifice plate pasting technology for consistent performance. They also include heavy-duty terminals, advanced lead alloy for corrosion resistance, and a flame-arresting safety venting system.

Standards and Compliance: Compliance with IEC60896-21/22, NEBS, BS 6290 PART 4, and EUROBAT standards. Classified as non-hazardous for transport by surface, marine, and air.

Construction: Utilizes a calcium/tin lead alloy for grids to reduce corrosion and grid growth. The separator is made of acid-resistant glass fibers to maintain electrolyte contact and prevent short circuits.

Safety Features: The safety release valve operates under normal pressure conditions, opening at pressures above 2 psi and resealing at 1.2 psi to prevent overpressure.

Performance Data: Includes detailed tables of battery models, capacities, dimensions, and discharge data, highlighting performance under various conditions and discharge times.

Cycle Life: Depicts cycle life in relation to Depth of Discharge (D.O.D) at +20°C, showing 100% D.O.D results in 700 cycles, while 10% D.O.D allows for up to 4200 cycles.

Recharge Characterization: Recommended charging voltage is 2.27 V/cell at 25°C, with guidance on recharging times based on charging current and capacity levels (50%, 70%, 90%).

Temperature Compensation: For temperatures above 25°C, subtract 3 mV/°C/cell; for temperatures below 25°C, add 3 mV/°C/cell to ensure optimal battery performance across different ambient temperatures.

Storage and Self-Discharge: Includes a graph showing self-discharge rates in relation to storage temperature, indicating capacity retention over time.

Conclusion: EverExceed's VRLA batteries are designed for high-rate discharge applications, with detailed specifications ensuring users can optimize performance based on environmental conditions and usage requirements.

High Rate Range VRLA CONSTRUCTION - AGM battery construction is as shown in the diagram below. The positive and negative grids are cast from a calcium / tin lead alloy to reduce grid growth and corrosion. The active material is manufactured from best high purity lead (99.994%) to minimize the negative effects of impurities. Separator is mat of random woven acid resistant glass fibres, which acts as sponge - soaking up and immobilizing the electrolyte whilst maintaining good acid to plate contact and availability during discharge. “U wrapping” is employed to eliminate the risk of short circuits...
