Battery Testing and Health Check Services

Why Does it matter?

UPS Battery Servicing 

The batteries connected to any UPS system are crucial to its continuous operation. Battery failure puts your business’s vital power continuity in jeopardy.

Most UPS batteries have a 5 or 10-year design life, but performance starts to deteriorate from the moment dioxide paste is applied to its grids in the factory.

Each battery cell and string behaves slightly differently and has a unique deterioration rate. This is affected by several factors such as ambient temperature, the frequency and depth of discharge, and how they are stored. 

Battery Health Check

We can offer a comprehensive battery check, run test and UPS health check for all leading UPS brands, including AEC, Riello, MGE, APC, Eaton, Powerware, Chloride, Gamatronic, Borri, Certa, Huawei, Tripp Lite, New Wave and others.

Battery Testing

Using the latest technology our advanced battery testing gives a more accurate look at overall battery health. The test is non intrusive and can be completed without having to dismantle the battery string saving time & money in the long run.

Battery Replacements

Recent testing may have highlighted a rogue battery block or entire string fault. With technical matching of the battery characteristics and a careful equalisation charge, we can replace either a single block or full battery string in your current installation.

UPS Battery Replacements and Maintenance

UPS Battery Replacement

The batteries are critical to the integrity of your UPS system. Most modern UPS systems will perform and monitor short battery tests on a regular basis, however it is also essential to maintain these systems to ensure they will operate correctly when needed.
UPS Power Services can supply, install, maintain or replace a wide variety of batteries, the most common being sealed lead acid (VRLA) with a 5 or 10 year design life.


UPS Battery Maintenance

Regular UPS battery maintenance is required to prolong the life of the batteries and to detect any weak or faulty battery blocks. We carry out the following checks:

  • Examining the batteries for any swollen, distorted or split casings
  • Measure battery cell and battery string voltages
  • Check for signs of corrosion
  • Check the tightness and security of battery terminal connections
  • Environmental checks, such as room temperature, cleanliness etc.
  • Battery discharge test (via UPS front panel or system load bank )

UPS Battery Rack Design

Every battery system design has to meet customer’s needs and accommodate any special requirements. Consideration is given to:

  • Battery requirements and type; such as autonomy (back-up) time and whether the batteries should be sealed lead acid (VRLA), vented lead acid, plante or nickel cadmium (NiCd)
  • Battery design life and the number of charge/discharges cycles
  • Parallel battery bank advantages
  • Room temperature conditions
  • Battery housing type; open, cladded or enclosed rack, matching UPS/battery cabinets etc
  • Room restrictions; false/raised floors (are battery rack leg extensions required?), dimensions (size) or surface load (weight)
  • Room accessibility; easy access, straight push, no steps, lift capacity, stairs and other obstacles
  • Battery monitoring system; continuously monitoring your battery health
  • Flexibility of individual battery string fusing and switchgear
  • DC cable lengths and power losses associated with long cable runs

UPS Battery Installation

Our battery installation and UPS battery replacement team will perform the following tasks:

  • Site survey to fully understand the task and site access

  • Produce a risk assessment and method statement (RAMS)
  • Co-ordinate and arrange delivery, positioning and installation of new batteries together with battery racks/cabinets
  • Install new DC fuses and switchgear (as specified)
  • Connect all batteries to UPS and create a complete system
  • Installation of battery monitoring system (as specified)
  • If we are providing a UPS battery replacement service, we may be able to isolate and change one parallel battery string at a time so that the integrity of the overall system is not compromised during the replacement process
  • Pack and remove old batteries from site for recycling and correct disposal. Providing a hazardous waste disposal certificate
  • If required, perform a system load bank test, discharging the batteries whilst monitoring battery performance and thermal imaging survey

    Its common knowledge that the battery system is the weakest link in a UPS and that battery failure is the leading cause of load loss and associated downtime.

    Understanding how to correctly store, install, check and maintain a UPS battery system will help prevent ultimate failure and also extend the service life of your current installation.

    Lets take a look at some frequently asked questions when it comes to UPS battery replacement and UPS battery maintenance.

    Can you change batteries on any UPS system?
    Yes is the short answer, depending on the size and type of UPS would determine how complex the replacement would be, but the principles are all the same. Our skilled battery engineers have worked on many systems over the years.
    Do you only supply Yuasa batteries?

    No, Yuasa is our prefered supplier. The level of quality from Yuasa and the warranty is exeptional in our experiance, they can supply almost any block in the UK within a day. We are a Yuasa main dealer, so can supply what we feel are the best batteries at the very best price. However if it is a specific battery you require we do have accounts with all the leading battery manufacturers.

    What does VRLA stand for?
    Valve Regulated Lead Acid.
    VRLA batteries work on the oxygen recombination principle. However, the recombination process is not 100% efficient. So over time, the internal pressure increases, and a certain amount of gases have to be released to maintain the ideal pressure. This is achieved with the help of one-way, pressure-sensitive valves which open when the internal pressure increases above a certain threshold and allow the excess gases to be vented. That is why these batteries are called VRLA or valve regulated lead acid batteries. Excess gases are also produced if these batteries are overcharged or discharged at rates higher than the recommended rate.
    What is sulfation and grid corrosion?
    Sulfation and grid corrosion are the main killers of lead acid batteries. Sulfation is a thin layer that forms on the negative cell plate if the battery is allowed to dwell in a low state-of-charge. During use, small sulfate crystals form, but these are normal and are not harmful. During prolonged charge deprivation, however, the amorphous lead sulfate converts to a stable crystalline and deposits on the negative plates. This leads to the development of large crystals that reduce the battery’s active material, which is responsible for the performance. If caught in time, an equalising charge can reverse the condition. Grid corrosion can be reduced with careful charging and optimisation of the float charge.
    Why do batteries need to be cooled?
    Heat is a killer of all batteries, but high temperatures cannot always be avoided. As a guideline, each 5°C rise in temperature cuts the life of a sealed lead acid battery in half. This means that a VRLA battery for stationary applications specified to last for 10 years at 25°C would only live 5 years if continuously exposed to 30°C and 30 months if kept at a constant temperature of 35°C. Once the battery is damaged by heat, the capacity cannot be restored.
    What is the "end of useful life" for a UPS battery?
    The IEEE defines “end of useful life” for a UPS battery as being the point when it can no longer supply 80% of its rated capacity in ampere-hours. When your battery reaches 80% of its rated capacity, the aging process accelerates, and you should replace it.
    How Does Age Affect Battery Life?
    Natural degrading is typically about 5% per annum, depending on the type and brand of battery. It is because of this degradation that you need to check the batteries to be sure that you will get your required and expected runtime during a mains failure. If the batteries aren’t in great condition then the autonomy time will be dramatically reduced and a planned, safe shutdown will not be achieved. Although regular maintenance and ideal environmental conditions can extend the working life of UPS batteries, they will eventually need replacing.

    {UPS Power Services have extended the life of our UPS by providing maintenance when APC would not. Bought new batteries from them at a reasonable price which they installed and took away the old ones. Have also had our first annual service check which gave a detailed report on the UPS. Both employees who have been to our offices have been polite and carried out the work cleanly leaving everything as it should be. Only in our first year with them but from our current dealings seem an honest company wishing to give good service with satisfied customers.
