Which type of power supply is most commonly used in portable medical equipment?

The most commonly used type of power supply in portable medical equipment is rechargeable lithium-ion batteries. These batteries are favored for several reasons. Firstly, they have a high energy density, which allows them to store a significant amount of energy in a small and lightweight package, making them ideal for portable applications where weight and size are critical considerations.

Additionally, lithium-ion batteries have a relatively long cycle life, meaning they can be charged and discharged many times before losing their capacity. This longevity is particularly important in medical settings, where equipment may need to function reliably over extended periods without frequent battery replacement.

Furthermore, lithium-ion technology has advanced significantly in terms of safety and efficiency, resulting in batteries that charge quickly and have built-in protection against overcharging and overheating. This is crucial in medical environments, where safety and reliability are paramount.

While other battery types, such as nickel-cadmium and alkaline batteries, do have their uses, they do not offer the same combination of performance, longevity, and safety features as lithium-ion batteries, thus making the latter the preferred choice in portable medical applications.
