The life span of a battery bloc can vary dramatically particularly when found in a UPS Program , the manufacturer will generally state the anticipated life of a battery bloc on the proviso that it includes a pure dc float voltage put on it and that the ambient temp is restricted to 20 ° C. If these parameters are adhered to, one can be prepared to achieve the 5 years existence from a 3 – 5 year design life electric battery or the 10 years of a 7 – 10 year design life battery pack bloc, omitting manufacturing failures.
Unfortunately we usually do not live in a perfect world and consequently there are restrictions applied to the battery bloc, one is the ambient heat, although numerous rack-attached UPS systems may luxuriate in ambient temperatures of 20 ° C or less because of the demands of the It all equipment, because of the nature of the design of the UPS there is normally insufficient space to attain a substantial airflow across the battery blocs and consequently they’ll fail the UPS system battery check after only 2 – 3 years.
In this situation the requirements of Uninterruptible power products and their set up mean that UPS maintenance is certainly unlikely to detect the failure of the battery power, often because of the fact that after an extremely short period of time the UPS system is hidden in a mass of communication cables. The most positive approach under these situations is definitely to rigorously put into action a two-year replacement battery programme to ensure the integrity of the back-up UPS program. This also pertains to Generators. Yes, also diesel generators need batteries to provide the current to start out.
Smooth or failed batteries render the generator worthless. Contact outs to such complications are chargeable and yet can be prevented by a normal maintenance regime.
In bigger UPS systems the problems arising tend to be due to location; no-one wants the neighborhood radiated noise of Uninterruptible power supplies to impinge on their operating environment and, consequently the uninterruptible power will be positioned in a basement maybe, where in fact the ambient temperature isn’t perfect for batteries and maybe the word,” Out of view is Out of mind,” is true. In the case of battery life, ignorance is not bliss. Batteries will fail the issue can be whether you are prepared or just looking forward to it to occur,
Due to the positioning the ambient heat range could exceed 25 – 30 ° C which potentially could reduce the expected existence of the battery pack. For, prolonged make use of at 30 ° of VRLA (valve regulated lead acid) batteries the expected life can decrease by 50%, if the ambient heat is elevated to 40 ° C the life of the battery will fall by another 50%. Therefore at an ambient temperatures of 40 ° C the expected operating lifestyle of a 7 – 10 year life electric battery has fallen to 1 1.75 – 2.5 years!
In this instance even emergency power supply manufacturer will not save the battery pack, all it could do is certainly to survey on the quick deterioration of the battery bloc.
Thankfully these extremes included in these scenarios are not too common however they highlight the necessity to record the operating circumstances by regular UPS maintenance and also to ensure that there is an emergency 24/7 callout cover in place in the event of the unexpected taking place. Be prepared!
