Power sources utilizing a 40-volt maximum lithium-ion configuration are commonly employed in cordless power tools and outdoor equipment. These batteries provide a substantial voltage output, enabling increased power and runtime compared to lower-voltage counterparts. For example, these power sources can operate demanding equipment like chainsaws, leaf blowers, and high-powered drills for extended periods.
The utilization of this type of battery offers several advantages. It allows for cordless operation, providing freedom of movement and eliminating the need for power cords. Furthermore, lithium-ion technology ensures a high energy density, meaning a significant amount of power can be stored in a relatively compact and lightweight package. Historically, nickel-cadmium batteries were prevalent, but lithium-ion options offer improved performance, longer lifespan, and are free from heavy metals, making them more environmentally friendly.
