The life span of a battery pack bloc can vary dramatically particularly when used in a UPS Program , the maker will often state the expected existence of a battery bloc on the proviso that it includes a natural dc float voltage applied to it and that the ambient temperatures is fixed to 20 ° C. If these parameters are honored, one can expect to achieve the 5 years existence from a 3 – 5 year design life battery or the 10 years of a 7 – 10 year style life battery bloc, omitting manufacturing failures.
Unfortunately we usually do not live in an ideal world and consequently there are limitations put on the battery pack bloc, one is the ambient temperature, although a number of rack-mounted UPS systems may luxuriate in ambient temperature ranges of 20 ° C or less because of the needs of the IT equipment, because of the nature of the look of the UPS there is normally insufficient space to achieve a significant airflow round the battery pack blocs and consequently they will fail the UPS system battery check after a mere 2 – three years.
In this situation certain requirements of Uninterruptible power supplies and their set up mean that UPS maintenance is certainly unlikely to identify the failure of the battery power, often due to the fact that after a very short time period the UPS system is concealed in scores of communication cables. The most positive strategy under these circumstances is normally to rigorously put into action a two-year replacement battery pack programme to ensure the integrity of the backup UPS system. This also pertains to Generators. Yes, even diesel generators require batteries to provide the current to start out.
Smooth or failed batteries render the generator ineffective. Call outs to such problems are chargeable and yet can be prevented by a regular maintenance regime.
In larger UPS systems the problems arising are often due to location; no-one wants the neighborhood radiated noise of Uninterruptible power items to impinge on their working environment and, consequently the uninterruptible power supply will be situated in a basement maybe, where the ambient temperature isn’t ideal for batteries and maybe the word,” Out of view has gone out of mind,” holds true. Regarding battery existence, ignorance is not bliss. Batteries will fail the query is certainly whether you are ready or just waiting for it to occur,
Because of the positioning the ambient temp can often exceed 25 – 30 ° C and this potentially could decrease the expected life of the electric battery. For, prolonged use at 30 ° of VRLA (valve regulated lead acid) batteries the expected existence can reduce by 50%, if the ambient temperature is raised to 40 ° C the life of the electric battery will fall by another 50%. Therefore at an ambient temperature of 40 ° C the anticipated operating lifestyle of a 7 – 10 year life battery has fallen to at least one 1.75 – 2.5 years!
In this instance even UPS Battery Manufacturer won’t save the electric battery, all it could do is usually to record on the rapid deterioration of the battery bloc.
Luckily these extremes included in these scenarios aren’t too common however they highlight the need to record the operating circumstances by regular UPS maintenance and to ensure that there can be an emergency 24/7 callout cover set up in the event of the unexpected taking place. Be prepared!
