UPS systems are designed to provide backup power in the event of a power outage or fluctuation. The lead-acid battery plays a crucial role in this process. When the primary power source fails, the UPS system switches to battery power, ensuring a seamless transition and continued power supply to critical loads. The capacity and performance of the lead-acid battery directly impact the UPS system’s ability to provide backup power. A battery with sufficient capacity can support the load for a longer duration, while a high-performance battery ensures a stable and reliable power output.
When choosing a lead-acid battery for a UPS system, several factors need to be taken into account:
Capacity: The capacity of the battery, measured in ampere-hours (Ah), determines how long it can support the load during a power outage. The required capacity depends on the size and power requirements of the UPS system and the intended backup duration.
Voltage: The voltage rating of the battery must match the requirements of the UPS system. Common voltage ratings for lead-acid batteries include 12V, 24V, and 48V.
Lifespan: The lifespan of a battery is determined by its cycle life and float life. Cycle life refers to the number of discharge-recharge cycles the battery can undergo, while float life measures its durability under continuous float charging conditions.
