Lithium-ion batteries are typically used in portable medical devices due to their high energy density, lightweight nature, and ability to hold a charge for extended periods. These characteristics make them ideal for use in devices that require reliable and consistent power without adding significant weight, which is critical for portability. Additionally, lithium-ion batteries support many charge cycles, allowing them to be recharged and used multiple times, which is essential for the functionality and operational efficiency of portable medical equipment.

While other battery types, such as nickel-metal hydride (NiMH) batteries, also find applications in some medical devices, they often do not offer the same energy capacity and longevity as lithium-ion. Lead-acid batteries, while robust and reliable, are typically heavier and bulkier, making them less suitable for portable applications. Alkaline batteries are often used in devices with lower power demands or for backup power but are not rechargeable and generally do not support the higher energy requirements of modern portable medical devices. Therefore, lithium-ion technology stands out as the preferred choice in this context.
