Uninterrupted power supply systems were developed mainly to help people enjoy using their computers even with uneven power flow from the grid. The system as a whole is therefore very useful. However, there are parts within which shoulder most of the burden. These include the UPS battery supply units among others.
When there is an interruption in the power flow, the batteries provide an alternative source. The only exception is when one has a flywheel energy storage system, which are very rare. With every blackout, the batteries help fill the vacuum until an alternative source such as a generator is started or the power from the grid returns.
For people with a simple system such as a home computer, the unit serves the purpose of providing them enough power to switch of the machine safely. This is because most of the systems have simple internal batteries that cannot last long enough for other purposes. With this limitation, people are seeking new ways to make their systems more useful.
The use of external batteries in blocks is one such alternative as it helps extend the time served by the internal battery. This extends the time offered by the system from a few minutes to 4 or even 6 hours of full power for the system. With such an option, it is possible to use the power for other purposes not just powering the computer.
Even though this option promises more benefits, you should note that it is as strong as its weakest battery. This means you must have a systematic way of testing the extra battery supply units. This will help you identify and replace any weak links in the system even when they have not fulfilled their expected life cycle.
The testing takes different approaches. There is the option of automatic testing carried out by the UPS system. You can also opt for load bank or electro chemical testing. With the automatic option, the system tests the system every 24 hours and plays an audio warning if any unit has a problem.
Although the automatic testing option is the quickest way to identify a problem, it is not very reliable. This means that one also needs to use the other two methods for proper analysis of the problem. Once you identify the source of the problem within the UPS battery supply units, you should replace it immediately even when it has not exhausted its expected lifespan, which is usually five to ten years for most of the units. After this, your system should function properly.
