The life of a battery bloc may differ dramatically particularly when found in a UPS Program , the manufacturer will often state the anticipated life of a battery bloc on the proviso that it has a 100 % pure dc float voltage put on it and that the ambient temp 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 design life electric battery or the 10 years of a 7 – 10 year style life battery pack bloc, omitting production failures.
Unfortunately we do not live in a perfect world and consequently there are limitations put on the battery bloc, one may be the ambient temperature, although a number of rack-attached UPS systems may luxuriate in ambient temps of 20 ° C or less because of the demands of the IT equipment, because of 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 will fail the UPS system battery check after only 2 – 3 years.
In this situation the requirements of Uninterruptible power materials and their installation mean that UPS maintenance is definitely unlikely to identify the failing of the battery power, often because of the fact that after a very short time period the UPS system is concealed in a mass of communication wires. The most positive approach under these circumstances can be to rigorously apply a two-year replacement battery programme to ensure the integrity of the back-up 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 worthless. Contact outs to such complications are chargeable yet can be avoided by a normal maintenance regime.
In bigger UPS systems the issues arising are often because of location; no-one desires the local radiated sound of Uninterruptible power supplies to impinge on the operating environment and, because of this the uninterruptible power will be situated in a basement probably, where the ambient temperature is not ideal for batteries and perhaps the word,” Out of view is Out of mind,” holds true. In the case of battery lifestyle, ignorance is not bliss. Batteries will fail the question is certainly whether you are ready or just looking forward to it to happen,
As a result of the positioning the ambient temperature could exceed 25 – 30 ° C and this potentially could reduce the expected lifestyle of the electric battery. For, prolonged make use of at 30 ° of VRLA (valve regulated lead acid) batteries the expected life 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 existence of a 7 – 10 year existence battery has fallen to at least one 1.75 – 2.5 years!
In this case even emergency power supply manufacturer won’t save the battery, all it can do is definitely to report on the speedy deterioration of the electric battery bloc.
Thankfully these extremes included in these scenarios are not too common but 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 the event of the unexpected happening. Be prepared!
