Three types of UPS batteries, how much do you know？
Uninterruptible power supplies (UPS) use three primary types of batteries: Nickel-Cadmium, Lead-Acid, and Lithium-Ion, each with its own set of advantages and disadvantages. Let’s start with key characteristics of each battery technology. Nickel-Cadmium (Ni-Cd) batteries: Ni-Cd batteries have a long lifespan（about 20 years design life） and can withstand high temperatures without significant performance degradation, making them a good choice for applications that require high reliability and durability in extreme climate conditions. They also have inherent resistance to overcharging. This means they are less prone to damage caused by overcharging, reducing the risk of performance issues. However, Ni-Cd batteries are relatively expensive. What’s more, the disposal and recycling processes at the end of their service life are extremely costly and have environmental impacts due to the toxicity of nickel and cadmium. Lead-Acid batteries: Lead-Acid batteries have two different types: Valve Re
