UPS Battery Impedance Testing

Besides testing your UPS (Uninterruptible Power Supply), it’s important that you test your UPS batteries. 

They are the core of your UPS system and if there’s an unrecognised fault, it can mean your system failing when you need it most. 

UPS Batteries don’t last forever and it’s common practice to replace your UPS systems batteries every 3-5 years when they are usually reaching the end of their natural life to make sure your UPS is fully functioning correctly. It’s entirely possible, however, for a battery to fail before then as a result of external factors like heat, frequency of use and amount of power discharged, which can lead to a ‘domino’ effect as related batteries try and pick up the strain. This is why we recommend using our services for battery testing, even if you purchased your batteries elsewhere.

How important is frequent testing for UPS Batteries?

While the majority of UPS (Uninterruptible Power Supply) available today will be able to monitor the voltage of a battery string, they do not monitor single cells and this can mean that if you aren’t careful you’ll need to replace a whole string of batteries and not just the single bad cell.

How does the UPS Battery test work?

The method to check each individual battery is known as a battery impedance test, conducted annually, and gives you a better picture of the battery’s health over time and will eliminate any faults.

As we test each individual battery rather than the string itself, we’ll see if any faults are likely by how the battery is currently functioning and can replace any faulty parts before they cause a problem. You’ll still need to swap every battery eventually, but through regular tests you can ensure your UPS will function when you most need it and avoid any unnecessary costs.

The duration of the UPS battery test is obviously dependent on the size of the unit and how many batteries will need to be tested but will likely take between 2-3 hours. The test requires a fully qualified engineer due to the high voltages involved within a UPS unit and must be conducted by a professional.

By contacting us here we can schedule an annual check of your UPS battery, UPS (uninterruptible Power Supply) or diesel generator to ensure your system is in perfect working order and limit the dangers of developing a fault. Save time and money with UPS Systems battery testing.
