The life span of a battery pack bloc may differ dramatically especially when found in a UPS Program , the maker will generally state the expected life of a electric battery bloc on the proviso that it has a real dc float voltage put on it and that the ambient temperatures is fixed to 20 ° C. If these parameters are honored, one can be prepared to achieve the 5 years lifestyle from a 3 – 5 year style life battery pack or the 10 years of a 7 – 10 year design life battery pack bloc, omitting production failures.
Unfortunately we do not live in an ideal world and because of this there are restrictions applied to the battery bloc, one is the ambient temp, although several rack-mounted UPS systems may luxuriate in ambient temps of 20 ° C or less because of the demands of the It all equipment, due to the nature of the design of the UPS there is generally insufficient space to accomplish a substantial airflow across the electric battery blocs and consequently they’ll fail the UPS program battery check after a mere 2 – 3 years.
In this situation the requirements of Uninterruptible power products and their set up imply that UPS maintenance is normally unlikely to detect the failure of the battery power, often because of the fact that after an extremely short period of time the UPS program is hidden in a mass of communication wires. The most positive strategy under these situations is to rigorously implement a two-year replacement battery programme to ensure the integrity of the back-up UPS program. This also applies to Generators. Yes, even diesel generators need batteries to supply the current to start.
Smooth or failed batteries render the generator useless. Contact outs to such complications are chargeable and yet can be avoided by a normal maintenance regime.
In bigger UPS systems the problems arising are often due to location; no-one desires the neighborhood radiated noise of Uninterruptible power supplies to impinge on their functioning environment and, consequently the uninterruptible power will be located in a basement perhaps, where in fact the ambient temperature isn’t well suited for batteries and perhaps the word,” Out of sight is Out of mind,” is true. Regarding battery lifestyle, ignorance is not bliss. Batteries will fail the query can be whether you are ready 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 life of the electric battery. For, prolonged make use of at 30 ° of VRLA (valve regulated lead acid) batteries the expected existence can reduce by 50%, if the ambient temp is elevated to 40 ° C the life of the battery pack will fall by another 50%. Therefore at an ambient heat range of 40 ° C the anticipated operating existence of a 7 – 10 year lifestyle battery pack has fallen to 1 1.75 – 2.5 years!
In cases like this even emergency power supply manufacturer will not save the battery pack, all it could do is usually to survey on the rapid deterioration of the battery bloc.
Thankfully these extremes covered by these scenarios are not too common however they highlight the need to record the operating circumstances by regular UPS maintenance and also to make sure that there is an emergency 24/7 callout cover in place in case of the unexpected taking place. Be prepared!
