DEATH, TAXES AND UPS BATTERY FAILURES...


It’s said that there are only two certainties in life - death and taxes. If you’re a Data Center Manager you can add a couple more certainties. Your util- ity company electricity supply will fail, and the batteries in your UPS system will fail. It is only a matter of time and a very serious matter if they happen at the same time.


Batteries are the most vulnerable part of any UPS installation. One would think that, because of this, batteries would be meticulously main- tained, but this is very rarely the case. Many batteries are not inspected or maintained other than during an annual UPS service visit. Unde- tected battery problems account for a whop- ping 80% of UPS failures!


UPS battery monitoring is not enough The battery monitoring that comes with UPS systems is at a rudimentary level. The UPS can- not identify faults within individual batteries, nor detect an imbalance in the performance of multiple strings. To ensure the integrity of the entire battery power supply, you need to be able to detect failing batteries before they com- promise the integrity of the entire system. The effectiveness of a battery monitoring system is proportional to the number of points that are monitored and the frequency that this occurs. With regular monitoring comes the accumula- tion of data, the ability to report and spot trends, and the ability to take timely remedial action.


Getting a return on the investment First and foremost, the purpose of UPS and bat- tery monitoring systems is to protect the enter- prise from the consequences of a power failure. The investment becomes cost-justified the very first time they are needed. What is seldom ap- preciated is that battery monitoring is an in- vestment even if there are no power failures. Batteries are expensive. Proper care and timely remedial action extends the life of the cells. Through reducing the need for discharge tests, there is a saving in the cost of labour.


The trends which come from regular moni- toring allow one to quite accurately predict battery end of life. This means that batteries are not replaced prematurely (which is expen- sive) or too late (which is risky, and potentially very expensive).


Warranty claim disputes are eliminated through having documentary evidence of the environment that the batteries have experienced.


Every user will have their own set of benefits and justification. Sometimes the payback is not just financial. The Health and Safety as- pects, such as keeping personnel away from hazardous battery rooms and away from sen- sitive plant, is becoming more and more of a consideration.


To quote Telecom New Zealand –


“PowerShield’s increased safety through optical isolation became very important to our system. The reduction in maintenance cost was an add- ed advantage.”


PowerShield – specialists in battery moni- toring Since 1996 PowerShield have specialised in the design and development of battery moni- toring systems. Now installed across five con- tinents, the PowerShield system is helping to protect data centres, banks, hospitals, tel- ecommunications, and a wide range of major commercial and industrial enterprises.


One of the reasons for PowerShield’s global ap- peal is that it is a modular system that is easily customized to meet each organization’s indi- vidual and specific requirements. For example, the PowerShield System can monitor up to 16 strings with a total of 1,280 batteries. And if this is not enough, using Link Battery Management software, the systems can be networked to al- low for the monitoring of an unlimited number of batteries.


But when all is said and done… The real purpose of a PowerShield battery mon- itoring system is that your organization is pro- tected through ensuring that when there is a power failure, there is not also a battery failure.


Knowing that everything that can be done has been done, is not only prudent, but also helps CIOs and Data Center managers sleep at night.
