Riello 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.

Unfortunately, no UPS battery will last forever. They all have an optimum number of charge-discharge cycles, and a design life based on optimum site conditions which are rarely met in real-life. So in fact while most batteries may have a predicted lifespan of 5 or 10 years, it’s actually best practice to replace them in year 3 or 4 (for 5-year versions) or 7 or 8 (in 10-year models).

It’s crucial to review battery performance at regular intervals. Frequently testing your UPS batteries will help maximise their lifespan, identify any cells that might require replacement, and reduce your risk of unexpected failure.

Preventative Battery Maintenance

Where possible, UPS battery replacement should be planned in advance at the appropriate point in their design life. This approach is far more cost-effective than having to replace an entire string unexpectedly which risks the possibility of damaging failure.

UPS Power Service partners with all major battery manufacturers and can source virtually any replacement cells. Batteries can be replaced on-site and your system brought back online in an efficient and pain-free manner.

    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 long can I store my batteries?
    When batteries are stored disconnected from a charger, their life will decrease. Due to the self-discharge characteristics of lead-acid batteries, it is recommended you charge them every three to four months of storage. After 12 months, permanent loss of capacity will start to occur. To prolong shelf life without charging, store batteries in a cooler environment.

    Why are UPS Batteries so Important?

    It is the battery that provides the UPS with power to continue running in the event of a mains failure.

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

    All lead acid batteries, wet or gel, are prone to natural decay and have a design life of five, ten or twelve years. This is caused by metals and acid sharing the same plastic container.

    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.

    Do You Have Doubts About Your UPS Battery Health?

    If you have any doubts about the condition of your uninterruptible power supply or stand-by emergency lighting system, we can offer a comprehensive check-up, service and UPS battery replacement service for all leading UPS brands, including AEC, Riello, MGE, APC, Eaton, Powerware, Chloride, Gamatronic, Borri, Huawei, New Wave, and any other make or model.
