Uninterruptible power supply systems have become increasingly common for business, home security and computing applications where losses of data due to power interruptions could cost thousands of dollars, compromised data or losses of long-term customers. UPS battery arrays can power anything from emergency lighting to full-service data centers. The best batteries for providing uninterrupted power offer reliability, longevity, safety, consistency and affordability.
UPS Battery Back-up Systems
UPS systems provide nearly instantaneous power when a service disruption could cause fatalities, injuries, data losses, inconvenience or costly disruptions of business. You can use a load calculator to determine how much power you need, and you can use serial and parallel configurations for generating higher voltage or higher current.
Finding the best battery for your needs depends on load characteristics, costs, maintenance requirements and self-discharge rates of the batteries. Most UPS systems use more than one cell, so your costs depend on how many batteries are needed and what kind of housing is required. Arranged serially, battery voltage increases. Parallel configurations increase current. Most systems use valve-regulated lead-acid batteries or sealed batteries because maintenance is minimal and costs are affordable. Although these batteries don’t require adding liquid, maintenance and testing is still important because excess heat and evaporation could reduce the charge and battery life.
