Expected Lifespan Of Lead-acid Batteries In Uninterruptible Power Supplies

In most uninterrupted power scenarios, lead-acid batteries can achieve a reliable service life of 3–5 years at room temperature of approximately 25°C.

Typically, industrial uninterruptible power supply batteries are sealed valve-regulated lead-acid (VRLA) batteries, the most common type of uninterruptible power supply (UPS) battery on the market.

Battery life is affected by various variables, such as ambient temperature, charge/discharge frequency, and battery quality.

If the operating temperature of ups electricity backup batteries is too high, their usable lifespan will be shortened prematurely.

Therefore, it is recommended to schedule professional testing or replacement for lead-acid batteries that have reached or exceeded 3–5 years of service life as soon as possible to maintain the stability of the small uninterruptible power supply backup power supply.
