UPS Batteries

UPS batteries are a critical component of any uninterruptible power supply system, delivering instant backup power during utility outages. These batteries store energy and discharge immediately when incoming power is disrupted, allowing connected equipment to continue operating or shut down safely. In environments such as data centers, healthcare facilities, manufacturing plants, and control systems, reliable battery performance is essential for minimizing downtime and protecting sensitive equipment. RSP Supply offers solutions from leading manufacturers such as Panduit and Phoenix Contact, supporting a wide range of industrial and commercial UPS applications.
Most UPS systems utilize sealed lead-acid (SLA) batteries due to their proven reliability and cost-effectiveness, while lithium-ion options are available for applications requiring longer life cycles, lighter weight, or improved energy density. Battery service life typically ranges from three to five years, depending on operating temperature, discharge frequency, and load conditions. Our selection includes individual replacement batteries, battery modules, and battery cartridges, as well as complete battery cartridge sets designed for streamlined maintenance and system compatibility.
Uninterruptible power supplies provide short-term power protection during outages and voltage irregularities. Standby (offline) UPS systems switch to battery power when voltage drops below a preset threshold, while online UPS systems continuously supply power through an inverter, providing seamless transition during disruptions. Additional support components such as external battery packs, battery cabinets, and battery cables help expand runtime capacity and maintain proper system configuration. In both configurations, the battery remains the core energy source that bridges the gap between power loss and generator startup or safe equipment shutdown.
FAQs
Q: What does a UPS battery do?
A UPS battery stores electrical energy and delivers it immediately when utility power is lost, allowing connected equipment to continue operating temporarily or shut down safely.
Q: How long do UPS batteries last?
Most UPS batteries have a service life of three to five years. Factors such as temperature, usage patterns, discharge frequency, and overall load can affect battery lifespan.
Q: What types of batteries are used in UPS systems?
Sealed lead-acid batteries are the most common type used in UPS systems. Some applications use lithium-ion batteries for longer service life, reduced weight, and improved energy efficiency.
Q: How do I know when to replace a UPS battery?
Indicators include reduced runtime, battery alarms, swelling, leakage, or system notifications. Routine testing and monitoring help identify declining performance before failure occurs.
Q: What is the difference between standby and online UPS systems?
Standby UPS systems switch to battery power when utility voltage drops outside acceptable limits. Online UPS systems continuously supply power through an inverter, providing seamless operation without switching delays.
