Battery Maintenance Service
Uninterruptible power supply (UPS) and DC Power Systems are used to provide emergency power to loads when AC mains power experience sudden interruptions/failures. The equipment to which they are connected may range from computers, servers to control systems critical to the company or plant’s continued operations. How do you know when the UPS will have sufficient reserve battery power to sustain operation until your back up generator kicks in? The printed rating in your battery nameplate may provide the system’s capacity but this is not the true capacity. Over time, the cells in the battery degrade whether they are used or not and lead to loss in capacity.
Routine maintenance procedures like cell or intercell connector voltage and internal resistance measurements can predict some problems but the only way to confirm a battery’s performance is to do a “Capacity testing”, otherwise known as “Load testing”. This is performed by discharging the battery and verifying that the battery voltage will remain above a minimum voltage in the specified period of time. A battery rated 12V/100Ah/C10 must be able to discharge a constant 10A every hour for 10 hours and final terminal voltage must not be lower than 10.8V to be considered 100% capacity.
Internal impedance of a battery increases with age, frequency of charging and discharging. Regular monitoring of internal battery impedance is necessary to avoid the risk of failure. Our advanced impedance testing procedures can help minimize the risk of failure, reinforce safety and reliability.
To comply with the safety and reliability requirements in the operations and ISO 9000 for Quality Management Systems, periodic discharge testing is necessary to determine the condition of each battery cell and its ability to perform on the design capacity.
We undertake various range tests for different types and capacity of battery. We start with a full battery installation survey to verify the initial information, specification, and as found condition of existing and new batteries. With our equipment and technical expertise you can be certain that your batteries will deliver peak performance for the longest time possible.
Batteries are vital parts in modern critical power systems. Periodic battery maintenance can protect your standby power requirements. Because batteries have finite lifespan, inadequate maintenance with continuous operational conditions can cause premature failure. These failures can compromise your standby power and increase the risk of opportunity loss to operate. Capacity testing should be performed on all critical battery applications, as its failure to supply full capacity can lead to unintended disruption to company operations.
