Are all UPS systems powered by lead-acid batteries?

Many people assume that all UPS systems use lead-acid batteries, but this is not necessarily the case. Lead-acid batteries are indeed very common, as they are cost-effective, feature mature technology, and require little effort for daily maintenance. The batteries inside UPS units are sealed, eliminating the need for electrolyte refilling—they are maintenance-free, making them ideal for users who lack the time or energy to tend to battery upkeep.

However, with technological advancements, lithium-ion batteries have also begun to be used in UPS systems. Lithium-ion batteries offer more advantages than lead-acid ones: they can store more electricity at the same size, provide longer runtime, have a service life 2-3 times longer, and charge much faster.

We develop lithium-ion battery-powered UPS systems. For example, our ET Series UPS units are equipped with brand-new lithium iron phosphate (LFP) batteries. These batteries can undergo over 1,600 charge-discharge cycles, making them extremely durable. Featuring single-phase input and output, they are double-conversion online UPS systems—boasting high efficiency and strong reliability, they supply stable AC power to equipment, ensuring peace of mind during use.

Lead-acid batteries are not the only option for UPS systems. When choosing a UPS, there’s no need to fixate on one type of battery. Simply align your choice with your actual needs, and select the one that best suits you.
