UPS the basics

Flame retardant batteries.

Valve regulated lead acid batteries (VRLA) are still the most commonly used batteries in the UPS market. A highly reliable energy source, ready to be called upon in the event of a mains power anomaly.

There are differences between the types of VRLA batteries available. Differences in output/performance. Differences in design life (in optimum conditions). Difference in physical size. Differences in terminal type. However, often overlooked is the difference between utilising FR (flame retardant) batteries and non-flame retardant blocks.

What’s the difference? Well, it’s generally about the susceptibility of the battery catching fire. FR type is generally made with materials less likely to result in a fire starting, whereas non-FR is more likely.

Why is there a choice? Why is there even a non-FR type available? We can only assume cost is the biggest influence here. There may be environmental issues with some parts being less recyclable in the FR type to the non-FR versions, too. This should be a consideration. Availability comes into decision making as well. Often, UPS systems are required urgently and batteries may be needed as part of replacement projects or new installations. In either case, battery availability may be a deciding factor for clients and power VARs.

In our opinion, wherever possible, FR batteries should be utilised. There are many causes of fires in buildings, of course, but the most likely system to cause a fire in a comms room or data centre is the UPS system, generally through poor housekeeping and lack of maintenance servicing.

When your UPS system is due for replacement, ask your incumbent to supply FR batteries, or better still, contact our team and we will support you with the safest batteries we can offer.
