A Guide To Batteries

The life of a electric battery bloc can vary dramatically especially when used in a UPS System , the maker will usually state the expected lifestyle of a electric battery bloc on the proviso that it includes a real dc float voltage applied to it and that the ambient heat is restricted to 20 ° C. If these parameters are honored, one can expect to achieve the 5 years lifestyle from a 3 – 5 year style life electric battery or the 10 years of a 7 – 10 year style life battery bloc, omitting production failures.

Unfortunately we usually do not live in an ideal world and consequently there are restrictions applied to the battery bloc, one may be 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, due to the nature of the design of the UPS there is normally insufficient space to attain a substantial airflow across the electric battery blocs and because of this they’ll fail the UPS program battery check after a mere 2 – three years.

In this situation certain requirements of Uninterruptible power supplies and their set up imply that UPS maintenance is definitely unlikely to identify the failing of the battery pack, often because of the fact that after an extremely short time period the UPS system is concealed in a mass of communication cables. The most positive approach under these situations is normally to rigorously implement a two-year replacement battery pack programme to ensure the integrity of the backup UPS program. This also applies to Generators. Yes, even diesel generators need batteries to supply the current to start out.

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

In bigger UPS systems the problems arising tend to be due to location; no-one wants the neighborhood radiated noise of Uninterruptible power items to impinge on their operating environment and, because of this the uninterruptible power supply will be located in a basement maybe, where in fact the ambient temperature isn’t well suited for batteries and maybe the saying,” Out of sight has gone out of mind,” is true. Regarding battery existence, ignorance isn’t bliss. Batteries will fail the question is normally whether you are prepared or just looking forward to it to occur,

As a result of the positioning the ambient heat could exceed 25 – 30 ° C and this potentially could reduce the expected life of the battery. For, prolonged make use of at 30 ° of VRLA (valve regulated lead acid) batteries the expected lifestyle can decrease by 50%, if the ambient heat range is raised to 40 ° C the life of the battery pack will fall by another 50%. Consequently at an ambient temp of 40 ° C the anticipated operating lifestyle of a 7 – 10 year life battery has fallen to 1 1.75 – 2.5 years!

In cases like this even emergency power supply manufacturer won’t save the battery, all it can do is to record on the quick deterioration of the electric battery bloc.

Fortunately 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 also to ensure that there is an emergency 24/7 callout cover set up in the event of the unexpected happening. Be prepared!
