This is the ninth in a series of units that will educate the reader on the part played by a battery in an uninterruptible power supply (UPS) system. Measuring the health of a valve-regulated lead-acid (VRLA) battery means more than just taking a voltage reading. A cell or battery can have the desired voltage when it has been sitting on float charge, but it might not have enough stored energy to support the critical load for more than a few [...]
This is the eighth in a series of units that will educate you on the part played by a battery in an uninterruptible power supply (UPS) system. IEEE Standard 1187 establishes the recommended practices for the design and installation of valve-regulated lead-acid (VRLA) batteries. The purpose of this paper is to highlight the most significant considerations identified in that standard, including: Safety considerations Design consideration Receiving and installation procedures IEEE 1188, which was discussed in Unit 8, describes the procedures [...]
This is the seventh in a series of units that will educate you on the part played by a battery in an uninterruptible power supply (UPS) system. Early on in a UPS design a decision must be made on whether batteries should be installed on racks or in cabinets. Both have pros and cons. The following are typical design considerations. Battery technology Vented lead-acid (VLA) (frequently referred to as “flooded” or “wet cell”) batteries, which are sometimes used on very [...]
Why attention to detail makes a big difference to getting the most out of your UPS battery investment. The global data center business is huge and growing fast, driven by the rapid digitisation of every type of business across almost every nation on earth. Within this scale and growth is the stark reality understood by data center operators – it is a game of small margins. Two facets in particular, installation and commissioning and ongoing monitoring, are key to staying [...]
According to a recent study from US-research firm Information Technology Intelligence Consulting (ITIC), over 80% of businesses need 99.99% availability from their data center. ITIC calculate that the average cost of this hour of annual downtime is $USD 260,000. Business owners simply can't afford to be offline, meaning end-to-end reliability and risk management are crucial. Given the huge growth in data storage requirements with cloud access, IoT and big data, minimising downtime is essential. Even a short-lived outage can have [...]
A battery management system is essential for the continued uptime and health of your data center. So it makes sense that when you've bought and installed one, you get the most out of it. We've recently published a new insights paper, How to make the most of that battery management system you just bought, and it's aimed at illustrating how to prevent your new BMS from becoming 'shelf-ware' - which basically means something that's underutilised. Putting your BMS on the [...]
This is the sixth in a series of units that will educate the reader on the part played by a battery in an uninterruptible power system (UPS). Following are definitions of terms that are used throughout this collection of technical papers.
In our previous blog, we introduced PowerShield 8 and its accompanying Link battery management software. We emphasised the importance of installing the software that comes with your battery management system (BMS), and this is especially true of Link software.

This blog, discussing battery Environmental and safety considerations, is the fifth in a series of units that will educate the reader on the part played by a battery in an uninterruptible power system (UPS). Environmental considerations fall into two categories: - the effects upon the battery by the environment in which it sits (small “e”); and - the effects of the battery upon the Environment in which it was produced, used, and disposed (big “E”) Impact of the environment on [...]
Despite a century of experience, collective knowledge, and wide-spread preference for lead-acid batteries, they are not without some short-comings. An earlier unit mentioned a couple of issues. In this unit we go into more depth about how, when and why a lead-acid battery might be made to fail prematurely. Most conditions are preventable with proper monitoring and maintenance. This list is not all inclusive, but some of the main considerations are...
Dr Martin Spencer of DataCentre220 was in the market for a new UPS and selected CBS Batteries and PowerShield as the best options. This article, featured in ElectroLink Magazine, discusses the benefits of each and how they came to be selected.
Data centers have nowhere to hide in this digital age, so tools that help them avoid outages and understand exactly how they are performing are becoming critical. For data center operators this makes it really important to clearly understand how their facilities are performing, and any potential threats to their uptime. Any interruption to their service becomes known almost immediately and not only costs revenue but results in dissatisfied customers, lost business and sometimes, irreversible damage to a hard-earned reputation.
This is the third in a series of units that will educate the reader on the part played by a battery in an uninterruptible power supply (UPS) system. In a previous unit we discussed various stationary lead-acid battery chemistries for UPS applications. In this unit we look at the role of battery charger subsystem. Charging regimes can generally be categorized into two types: intermittent and float
This is the second in a series of units that will educate the reader on the part played by a battery in an uninterruptible power system (UPS). In our introductory unit we pointed out that lead-acid batteries are the preferred method of energy storage for UPS systems in about 95% of all data center applications. We also stated that lead-acid batteries can be split into two main categories or technology types: valve-regulated or vented.
This is the first in a series of units that will educate the reader on the part played by a battery in an uninterruptible power system (UPS). Of the three main subsystems, the battery is what makes the system “uninterruptible”. Depending upon the system design, the battery can constitute as much as 50% of the cost of the UPS. Without a reliable battery, the operation of the entire data center can be put at risk. Power interruptions are rare and unpredictable, but when they occur they can disrupt the entire business or operation. Costs of downtime can range from hundreds to millions of dollars, depending upon the mission of the data center.
Global Data Center news site, DatacenterDynamics has featured our new offering, PowerShield 8, in a recent post. Discussing the benefits and improved UPS reliability, the post showcases our positioning in the marketplace. To read the article, click here.
PowerShield, market leaders in the provision of UPS battery management systems, today announced the release of PowerShield 8, a component-based solution that signals a new era in the protection of UPS battery backup systems. “The traditional approach of simply monitoring battery health is no longer sufficient for data centre operators,” says PowerShield CEO Len Thomas, “they need to not just be able to ensure battery availability, but also maximise their investment by optimising battery lifecycles.”
No data centre can throw endless sums of money towards ensuring maximum, continuous performance. Immense pressures exist to drive cost down, across the board. It instead becomes a case of finding smart, effective solutions that have a positive return on the investment. One strategy for reducing long-term UPS battery back-up costs for data centres is using battery monitoring and management systems. These systems make the health and performance of batteries more visible, helping to identify any potential issues or faults with the batteries before they fail and impact the business.
In this digital age the performance of data centres is increasingly critical to an organisation’s reputation, in almost every industry sector. That puts immense pressure on data centres to perform, and makes the impact of failures more acute. Procedures like a discharge test (also known as a load test or capacity test, which accurately measures the true capacity of a battery system and in turn determines the health of batteries) can make all the difference between happy customers and reputational disaster.
One of the biggest international data conferences, Data Center World, is coming up and the team at PowerShield are looking forward to unveiling an exciting new product to help you get maximum juice out of your batteries. Introducing the PowerShield Controller; the PowerShield Controller system is the most advanced and most cost-effective tool for monitoring and managing stand-by battery banks. This gives you more ‘up time’ for your battery banks, and gets more out of your batteries.
PowerShield and Assidua Technologies last week, 26 February 2016, signed a Memorandum of Understanding enabling Assidua to distribute PowerShield’s specialist battery monitoring systems throughout Sri Lanka. The signing took place in the Ceylon Chamber of Commerce and was witnessed by New Zealand Prime Minister John Key and Sri Lankan Minister of Telecommunication and Digital Infrastructure Harin Fernando.
UPS system failure, including UPS and batteries, is the No. 1 cause of unplanned data center outages, accounting for one-quarter of all such events. This is according to the 2016 Cost of Data Center Outages report published by Emerson Network Power and the Ponemon Institute. The average total cost per minute of an unplanned outage in this report is USD 8,851, up from USD 7,908 in 2013. It just makes sense to mitigate the risks of outages caused by battery failure with a quality battery monitoring system.
