Introducing Batteries

The life of a battery pack bloc can vary dramatically particularly when found in a UPS System , the manufacturer will usually state the expected existence of a electric battery bloc on the proviso that it includes a real 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 be prepared to achieve the 5 years lifestyle from a 3 – 5 year style life battery pack or the a decade of a 7 – 10 year style life battery pack bloc, omitting manufacturing failures.

Unfortunately we do not live in a perfect world and consequently there are limitations put on the battery pack bloc, one is the ambient heat, although a number of rack-mounted UPS systems may luxuriate in ambient temps of 20 ° C or less due to the demands of the IT equipment, because of the nature of the look of the UPS there is generally insufficient space to accomplish a substantial airflow across the battery blocs and consequently they will fail the UPS program battery check after only 2 – three years.

In this example certain requirements of Uninterruptible power materials and their installation mean that UPS maintenance is normally unlikely to detect the failing of the battery pack, often because of the fact that after an extremely short period of time the UPS program is concealed in a mass of communication wires. The most positive strategy under these circumstances is usually 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.

Flat or failed batteries render the generator ineffective. Contact outs to such complications are chargeable and yet can be avoided by a regular maintenance regime.

In larger UPS systems the issues arising are often due to location; no-one wants the local radiated sound of Uninterruptible power products to impinge on the operating environment and, consequently the uninterruptible power supply will be situated in a basement perhaps, where the ambient temperature is not ideal for batteries and maybe the word,” Out of sight has gone out of mind,” is true. Regarding battery lifestyle, ignorance is not bliss. Batteries will fail the question can be whether you are ready or just looking forward to it to happen,

As a result of the location the ambient heat could exceed 25 – 30 ° C which potentially could decrease the expected existence 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 span of the electric battery will fall by another 50%. As a result at an ambient heat range of 40 ° C the expected operating life of a 7 – 10 year existence electric battery has fallen to 1 1.75 – 2.5 years!

In this instance even emergency power supply manufacturer will not save the battery, all it can do is to report on the rapid deterioration of the electric battery bloc.

Luckily these extremes covered by these scenarios aren’t too common but they highlight the necessity to record the operating conditions by regular UPS maintenance and to make sure that there is an emergency 24/7 callout cover in place in case of the unexpected taking place. Be prepared!
