The life of your battery bloc can vary dramatically most importantly when used in the UPS System, the manufacturer will always state the expected life of your battery bloc upon the proviso that it features a pure dc float voltage applied for it which the ambient temperature is restricted to twenty ° C. If these parameters are followed, one can get to obtain the 5 years life given by a 3 – 5 year design life battery as well as 10 numerous years of a 7 – 10 year design life battery bloc, omitting manufacturing failures.
Unfortunately we don’t live in the perfect world and consequently there may be limitations applied towards the battery bloc, one will be the ambient temperature, although several rack-mounted UPS systems may luxuriate in ambient temperatures of 20 ° C or less due to the demands from the IT equipment, a result of the nature of the planning from the UPS There’s generally insufficient space to obtain a big airflow round the battery blocs and consequently they’re going to fail the UPS system battery test from a mere 2 – 3 years.
During this situation the requirements of Uninterruptible power supplies and the installation mean that UPS maintenance is unlikely to detect the failure from the battery pack, often a result of the proven fact that after a really short time the UPS method is hidden in the mass of communication cables. The foremost positive approach under these circumstances usually is to rigorously implement a two-year replacement battery programme to ensure the integrity from the backup UPS system. This also relates to Generators. Yes, even diesel generators require batteries to give you the current to start out.
Flat or failed batteries render the generator useless. Call outs to such complaints are chargeable nevertheless could be avoided using a regular maintenance regime.
In larger UPS systems the issues arising tend to be as a result of location ; no-one wants the local radiated noise of Uninterruptible power supplies to impinge on the working environment and, consequently the uninterruptible power supply will certainly be located in the basement perhaps, in which the ambient temperature Isn’t ideal for batteries and possibly even the saying, ” Away from sight is Away from mind, ” is true. Inside the case of battery life, ignorance Isn’t bliss. Batteries will fail the question is even if prepared or just simply expecting it to happen,
Because of the location the ambient temperature could exceed 25 – 30 ° C which potentially could decrease the expected life from the battery. For, prolonged use at 30 ° of VRLA (valve regulated lead acid) batteries the expected life can decrease by 50%, in the event the ambient temperature is raised to 40 ° C the life from the battery will fall by another 50%. Therefore at an ambient temperature of 40 ° C the expected operating life of your 7 – 10 year life battery has fallen to 1. 75 – 2. 5 years!
During this case even UPS maintenance won’t use battery, all it can perform usually is to report upon the rapid deterioration from the battery bloc.
Fortunately these extremes covered by these scenarios aren’t too common however they highlight the got to record the operating conditions by regular UPS maintenance and in order that there’s an emergency 24/7 callout cover set up in case from the unexpected happening. Be prepared!
