Characteristics Of Batteries

The life of a electric battery bloc may differ dramatically specially when used in a UPS Program , the maker will often state the expected lifestyle of a electric battery bloc on the proviso that it has a real dc float voltage put on 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 existence from a 3 – 5 year design life battery or the a decade of a 7 – 10 year design life electric battery bloc, omitting manufacturing failures.

Unfortunately we usually do not live in an ideal world and as a result there are restrictions applied to the electric battery bloc, one may be the ambient temp, although numerous rack-attached UPS systems may luxuriate in ambient temperature ranges of 20 ° C or less because of the demands of the IT equipment, because of the nature of the look of the UPS there is normally insufficient space to attain a substantial airflow across the battery blocs and because of this they’ll fail the UPS system battery test after only 2 – three years.

In this situation certain requirements of Uninterruptible power products and their set up mean that UPS maintenance is unlikely to identify the failing of the battery power, often because of the fact that after an extremely short period of time the UPS system is concealed in a mass of communication cables. The most positive strategy under these circumstances can be to rigorously apply a two-year replacement electric battery programme to ensure the integrity of the backup UPS program. This also pertains to Generators. Yes, even diesel generators need batteries to provide the current to start out.

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

In larger UPS systems the issues arising are often because of location; no-one desires the neighborhood radiated sound of Uninterruptible power supplies to impinge on their operating environment and, as a result the uninterruptible power will be situated in a basement probably, where the ambient temperature isn’t ideal for batteries and perhaps the word,” Out of view is Out of mind,” is true. Regarding battery existence, ignorance is not bliss. Batteries will fail the question is whether you are ready or just waiting for it to occur,

Due to the positioning the ambient temperature can often exceed 25 – 30 ° C which potentially could reduce the expected existence of the battery pack. For, prolonged make use of at 30 ° of VRLA (valve regulated lead acid) batteries the expected existence can reduce by 50%, if the ambient heat range is raised to 40 ° C the life of the battery will fall by another 50%. Therefore at an ambient temperature of 40 ° C the expected operating lifestyle of a 7 – 10 year existence electric battery has fallen to at least one 1.75 – 2.5 years!

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

Fortunately these extremes covered by these scenarios are not too common but they highlight the need to record the operating conditions by regular UPS maintenance and to make sure that there can be an emergency 24/7 callout cover in place in the event of the unexpected taking place. Be prepared!
