The life of a electric battery bloc may differ dramatically particularly when found in a UPS System , the manufacturer will often state the anticipated life of a battery pack bloc on the proviso that it includes a 100 % pure dc float voltage put on it and that the ambient temperatures is fixed to 20 ° C. If these parameters are honored, one can expect to achieve the 5 years lifestyle from a 3 – 5 year design life battery or the 10 years of a 7 – 10 year style life electric battery bloc, omitting production failures.
Unfortunately we do not live in an ideal world and consequently there are restrictions applied to the electric battery bloc, one may be the ambient temperatures, although numerous rack-mounted UPS systems may luxuriate in ambient temps of 20 ° C or less because of the needs 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 round the electric battery blocs and because of this they’ll fail the UPS program battery check after a mere 2 – three years.
In this example the requirements of Uninterruptible power items and their set up imply that UPS maintenance is certainly unlikely to identify the failure of the battery pack, often due to the fact that after an extremely short period of time the UPS program is concealed in a mass of communication wires. The most positive approach under these circumstances is to rigorously implement a two-year replacement battery pack programme to ensure the integrity of the back-up UPS system. This also applies to Generators. Yes, even diesel generators need batteries to supply the current to start.
Flat or failed batteries render the generator useless. 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 desires the neighborhood radiated noise of Uninterruptible power items to impinge on their operating environment and, because of this the uninterruptible power will be situated in a basement perhaps, where the ambient temperature isn’t well suited for batteries and perhaps the word,” Out of view is Out of mind,” is true. In the case of battery lifestyle, ignorance is not bliss. Batteries will fail the question can be whether you are prepared or just looking forward to it to occur,
As a result of the positioning the ambient temp can often exceed 25 – 30 ° C and this potentially could decrease the expected lifestyle of the battery. For, prolonged use at 30 ° of VRLA (valve regulated lead acid) batteries the expected life can reduce by 50%, if the ambient heat is elevated to 40 ° C the life span of the battery will fall by another 50%. Consequently at an ambient temp of 40 ° C the anticipated operating life of a 7 – 10 year lifestyle battery pack has fallen to 1 1.75 – 2.5 years!
In this instance even Baykee UPS battery will not save the battery pack, all it could do is normally to report on the fast deterioration of the electric battery bloc.
Luckily these extremes covered by these scenarios are not too common but they highlight the need to record the operating circumstances by regular UPS maintenance and to make sure that there is an emergency 24/7 callout cover in place in the event of the unexpected taking place. Be prepared!
