Home > Products > Batteries > CV Series 20yr VRLA


The most comprehensive range of VRLA battery systems designed for standby applications that require reliable power and long life.

 


Applications

  • Telecom, wired and wireless.
  • UPS.
  • Switchgear.
  • Renewable Energy.
  • Emergency Lighting.

Features

Design Life 20 years in float service at 77° F (25° C)
Patented catalyst in each cell Improves life by lowering float current, reducing grid corrosion and reducing water loss. It°s effects are even more apparent in higher temperatures.
Separators: Micro porous glass mat, H&V is standard.
Plate protection: Plate growth without damage is allowed by a collapsible bridge installed in the bottom of the container.
Electrolyte: Sulphuric acid solution, 1.300 s.g, when fully charged.
Float Voltage: 2.25 volts per cell at 77° F (25° C).
Self-discharge rate: 2% per month at 77° F (25° C).
Intercell connectors: Plated copper bussbars.
Internal air passages Aid heat dissipation, and ensure consistent cell temperatures.
Cell fronts Protected with a transparent, FR plastic cover.
Modules: Stackable to 8 high while certified to UBC seismic zone 4, Welded steel construction, Internal air passages aid heat dissipation, ensure consistent cell temperatures, Coated with an acid resistant powdered epoxy.

About the Catalyst Valve

  • Patented by Philadelphia Scientific

Effect on the cells/battery

  • Lowers the float current draw
  • Reduces the rate of positive grid corrosion
  • Converts gases created inside the cell back to water, thus enabling the recombination process to function at maximum efficiency
  • Prevents the negative plate from becoming discharged while on float charge thus maintaining full cell capacity
  • Greatly reduces the loss of water through the valve, preventing early failure from cell dryout
  • It will not allow excessive heat to build if the battery is charged at too high a rate. It will allow the gases to bypass the catalyst if the temperature reaches a set level
  • The catalyst active material will last the lifetime of the battery under normal operating conditions

Solid rack construction


The latest in production equipment is used for consitant reliability.



Post seals consistent of a two-stage application of epoxy.



Cells are given high rate and cycle tests in the labs, using large capacity equipment.

 
  • Battery Model: To designate the model of the battery system, specify the number of cells in the system, followed by the cell type: i.e. 24CV 1050 would be a 24 cell, 48 volt battery with a capacity of 1050 AH at the 8 hour rate 10 1.75 VPC.
  • ** Overall depth: The module depth includes the module cover. The overall depth including the base assembly is 24” / 610 mm.
  • *** Overall height: To determine total number of module heights, add the total number of module height plus 4” / 102 mm for the base assembly and 6” / 152.4 mm for the terminal assembly.
