All About Batteries

The life span of a battery pack bloc can vary dramatically especially when used in a UPS Program , the manufacturer will constantly state the anticipated life of a battery pack bloc on the proviso that it has a natural dc float voltage applied to it and that the ambient temperature is restricted to 20 ° C. If these parameters are adhered to, one can be prepared to achieve the 5 years life from a 3 – 5 year design life battery or the 10 years of a 7 – 10 year style life electric battery bloc, omitting production failures.

Unfortunately we do not live in an ideal world and consequently there are restrictions put on the electric battery bloc, one may be the ambient temperatures, although several rack-mounted 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 look of the UPS there is normally insufficient space to attain a significant airflow across the battery pack blocs and as a result they’ll fail the UPS system battery test after only 2 – three years.

In this example the requirements of Uninterruptible power items and their installation mean that UPS maintenance is certainly unlikely to detect the failing of the battery pack, often due to the fact that after a very short time period the UPS program is hidden in scores of communication wires. The most positive strategy under these circumstances can be to rigorously put into action a two-year replacement electric battery programme to guarantee the integrity of the backup UPS program. This also applies to Generators. Yes, even diesel generators need batteries to supply the current to start.

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

In bigger UPS systems the issues arising are often due to location; no-one desires the neighborhood radiated noise of Uninterruptible power materials to impinge on their functioning environment and, as a result the uninterruptible power supply will be positioned in a basement probably, where the ambient temperature is not well suited for batteries and perhaps the word,” Out of sight is Out of mind,” holds true. In the case of battery life, ignorance is not bliss. Batteries will fail the question is usually whether you are ready or just waiting for it to happen,

Due to the positioning the ambient temperatures could exceed 25 – 30 ° C which potentially could decrease the expected lifestyle of the battery pack. For, prolonged use at 30 ° of VRLA (valve regulated lead acid) batteries the expected life can reduce by 50%, if the ambient heat range 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 anticipated operating existence of a 7 – 10 year existence electric battery has fallen to 1 1.75 – 2.5 years!

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

Fortunately these extremes included in these scenarios aren’t too common but they highlight the necessity to record the operating conditions 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 taking place. Be prepared!
