Battery replacement, testing, installation & disposal

UPS batteries are the most important aspect of an uninterruptible power supply. It is the UPS battery that provides the UPS system with its power in the event of a mains failure.

An old or badly maintained UPS battery set could affect the autonomy time of your uninterruptible power supply and result in a massive problem should you get a mains failure.

Load bank testing

Load bank testing provides information on a battery’s autonomy at the time of the test, as well as the integrity of all the electrical interconnections. The test is carried out when the uninterruptible power supply (UPS) is under load conditions to ensure the batteries are working optimally or to show whether any of the batteries are approaching the end of their working life or about to fail. The test is carried out with a device, the load bank, which develops an electrical load, applies the load to the UPS system or generator and converts or dissipates the resultant power output of the source.

When testing a system, the load bank should be placed no more than 20 meters from PDU or UPS terminals. However, it is important to remember allowances for heat dissipation need to be addressed to allow the load bank fans to cool the system. A resistive load stimulates real-life resistive loads, such as incandescent lighting and heating loads as well as the resistive or unity power factor component of magnetic loads.

Upon completion of a load bank test, system performance is determined using measurements taken during discharge. The test is useful for identifying problems with generators or UPS systems prompting immediate actions to be taken to facilitate its efficiency.

Impedance testing

Impedance testing is a way of monitoring the internal resistance to indicate which cells are weakest, or abnormal and may lead to a future battery failure. An electrical current is passed through each battery sequentially to decipher the internal impedance of each battery.

As a battery ages its impedance increases, where a lower internal resistance generally indicates a higher capacity. An increase can indicate declining battery capacity, or degradation.



We are committed to providing value by offering top battery products and services at competitive prices, ensuring exceptionally high customer service delivery.

Preserve the life of UPS batteries

The finite lifespan of a battery is determined by its speed of change in characteristics, both mechanically and chemically. Unlike measuring the charge a battery holds, this method of testing can actually determine battery health. This is achieved by taking into account a number of intrinsic and extrinsic factors, such as the type of cell, the cell’s beginning of life characteristics, the mode of battery failure, electrical interference, the application in which it is being used and the ambient temperature.

At Power Control we determine not only the voltage and impedance, but with our advanced battery test, we simultaneously measure the electrical and chemical properties of the batteries by measuring sulfation, dryout, voltage and impedance (SDVI).



“ A big thank you to your team on a very professional piece of work. From start to the end, well organised, and a bunch of Hard-working Lads. I Wish all of our contractors had your work ethics. ”
Account Manager at CBRE
“ This latest project with Power Control has really reinforced the importance of having regular battery maintenance with us (Briar Chemicals). The speedy response from Power Control has meant that we were able to be up and running again in a matter of days. ”
Nick Burr, IT Manager Briar Chemicals
“ The contract put together for us perfectly suits our needs and has not only given us peace of mind that all our systems are running safely and correctly but has also reduced the lifetime costs of the equipment. ”
Humayun Mirza, IT Manager at the University of Bedfordshire

Power Control’s chemical battery testing is crucial to adhere to a strict and solid maintenance prevention strategy for your critical equipment. Detecting battery irregularities and chemical changes early on allows the user to take preventative action before serious consequences arise. By allowing such incredible technical advancements to be freely available to clients Power Control is able to dramatically reduce the cost and risk of battery ownership like never before.

UPS battery disposal service

All exhausted UPS batteries are hazardous. If you require the removal and disposal of old or recently replaced batteries, Power Control will arrange collection and ensure safe and environmentally friendly disposal of any sealed lead-acid batteries. All works are carried out to environment agency standards.
