The life span of a battery bloc may differ dramatically specially when found in a UPS Program , the manufacturer will often state the expected existence of a battery pack bloc on the proviso that it has a 100 % pure dc float voltage applied to it and that the ambient heat range is restricted to 20 ° C. If these parameters are adhered to, 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 manufacturing failures.
Unfortunately we do not live in an ideal world and because of this there are restrictions applied to the battery pack bloc, one may be the ambient temperature, although several rack-attached UPS systems may luxuriate in ambient temperatures 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 normally insufficient space to accomplish a significant airflow round the battery blocs and as a result they will fail the UPS program battery test after a mere 2 – three years.
In this situation certain requirements of Uninterruptible power supplies and their installation mean that UPS maintenance is normally unlikely to identify the failure of the battery power, often due to the fact that after an extremely short period of time the UPS system is hidden in a mass of communication wires. The most positive approach under these circumstances is usually to rigorously implement a two-year replacement electric battery programme to guarantee the integrity of the backup UPS system. 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. Call outs to such complications are chargeable yet can be avoided by a normal maintenance regime.
In larger UPS systems the problems arising tend to be due to location; no-one desires the neighborhood radiated sound of Uninterruptible power products to impinge on the functioning environment and, because of this the uninterruptible power supply will be situated in a basement maybe, where the ambient temperature is not ideal for batteries and perhaps the saying,” Out of view has gone out of mind,” is true. In the case of battery existence, ignorance isn’t bliss. Batteries will fail the issue is usually whether you are ready or just looking forward to it to occur,
Because of the positioning the ambient temperature can often exceed 25 – 30 ° C and this potentially could reduce 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 temperature is raised to 40 ° C the life of the electric battery will fall by another 50%. Consequently at an ambient temp of 40 ° C the expected operating life of a 7 – 10 year life battery has fallen to at least one 1.75 – 2.5 years!
In this instance even Baykee UPS battery will not save the battery pack, all it can do is normally to survey on the speedy deterioration of the battery pack bloc.
Fortunately these extremes covered by 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 can be an emergency 24/7 callout cover in place in the event of the unexpected happening. Be prepared!
