|To facilitate smooth functioning in banking, insurance and in other service institutions, it became necessary to maintain the latest financial software packages, global networking facilities and user-friendly ATM services. This, in turn, has led to a large-scale computerization and consequent need for back-up power or Uninterrupted Power Supply (UPS), to avoid the ever-increasing problem of power failure. The integral part of a UPS is the battery bank. The battery acts as a back-up power source that supports the UPS system. The most popular battery system being used with UPS is the Lead acid battery system. Broadly there are two types of Lead Acid batteries suitable for UPS – SMF VRLA batteries and Tubular batteries.
VRLA batteries are flat plate batteries, which do not require periodic topping-up with water and normally do not emit any fumes or gases on a continuous basis. They are best suitable for applications where back-up requirement is usually short, normally not exceeding 30 mins to 1 hour. These batteries are automatic choice where ambient temperature is not very high and space is constraint. Exide’s Powersafe VRLA batteries are a superior range of products that provide ideal back-up power for UPS systems.
Tubular batteries use a special technology by which the active material is encapsulated in polyester tubes to prevent ‘shedding’. These types of batteries are recommended for back up power for UPS where environmental conditions are tough and high ambient temperature are common.
