UPS (Uninterruptible Power Supply) maintenance and repair are two distinct but equally crucial services for ensuring continuous power to critical equipment. Maintenance is a proactive strategy focused on preventing failures before they occur. It includes routine tasks such as visual inspections for signs of wear, cleaning internal components to prevent overheating, and regular testing of the battery's health and charge capacity. This preventative work extends the lifespan of the UPS and avoids unexpected downtime. In contrast, repair is a reactive service that fixes a specific problem after it has happened. Common repairs involve replacing failed batteries, repairing a faulty inverter, or addressing issues with the control board. A comprehensive service plan typically includes both, ensuring that the UPS is not only fixed when it breaks down but also routinely maintained to operate reliably.
