Uninterruptible Power Supplies – Battery Storage and Disposal

The batteries uninterruptible Power Supply play a central role in a business continuity plan providing a power supply DC power to the UPS UPS types when power fails. UPS Batteries use a chemical process to produce and store energy. When they are old or are damaged they can corrode and leak potentially harmful toxins in their environment. Over time, their effectiveness is also deteriorating. For these reasons UPS batteries must be stored and disposed of in compliance with a number of British and European directives, particularly the United Kingdom to the Environmental Protection Act 1990. Hazardous Waste Regulations 2005 also apply.

A Battery Pack is self-contained, electro-chemical device that stores electrical energy for later use. The outer case is usually made PVC polypropylene (which may be flame retardant) and has two protruding terminals (positive and negative). Inside, the positive and negative plates are immersed in an electrolyte, typically sulfuric acid to form cells with an electric potential. That tension is created and then stored when a charging current is applied.

The most common type of batteries used in uninterruptible power supplies is Sealed Lead-acid, but there are others: Nickel-Cadmium, for example, or Lithium-ion and alkaline silver.

UPS storage battery: A battery discharge same age and when not in use. The typical shelf life of a battery of six to 12 months and much depends environment in which they are stored, in particular the ambient temperature. Internal rate of discharge of a battery will also affect its aging process. Toll free for long periods, the battery performance will decrease.

The most important factor for preserving the life of UPS batteries, the temperature, the ideal is a constant 20-25 ° C (UPS battery life is halved for every five degrees above or below this level). To maintain temperature, a UPS and UPS Battery Set (especially those running in crowded data centers) require an efficient cooling system, which is a factor to be considered during specification of UPS.

For ongoing care supply distributors must be taken to monitor the actual time of the inverter and batteries are left without charge because it can lead to a profound rejection and potentially lead to the need for complete replacement of the battery set.

United Kingdom and guidelines European fight against storage and disposal of batteries UPS

– Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC

EU End of Life (ELV's) Directive (September 2000)

– EU Batteries Directive (May 2006)

The batteries are classified as hazardous waste because of their toxic components. In essence the batteries can not simply be "thrown" or entered into landfill. They must be disposed of in a manner protective of the environment and to comply with the law in most countries, this should be made by companies licensed to perform these tasks on behalf of manufacturers (which bear the ultimate responsibility). Riello UPS is a manufacturer of such power without interruption is also authorized to dispose of UPS batteries. Working with a provider of UPS ISO 14001 provides peace of mind especially if they are licensed to carry waste. They will in turn work alongside a licensed disposal company and thus ensure their growing needs of the uninterruptible power supply does not harm the environment.
