What are lithium batteries?
Lithium batteries are a type of rechargeable battery that work by moving lithium ions from negative electrodes to positive electrodes while discharging power, then move the lithium ions the opposite direction while charging. This kind of battery is used in many large, electric machines such as hybrid cars and self driving cars.

How do these batteries work?
These batteries generate power through chemical reactions between lithium, nickel, manganese, and cobalt. The strong reaction that occurs causes currents to flow between the positive and negative poles, creating an electric charge. The key to success lies in the combination of nickel and manganese. Nickel is known for having high specific energy but has poor stability. On the contrary, manganese has low internal resistance, resulting in high stability, as well as a low specific energy. Combining these two metals enhances each other strengths.

How long will the battery charge last?
The battery life varies depending on which tool is installed in the machine. The vacuum tool pulls more power and lends itself to an 8-hour battery life. The sweeper tool requires less power and will last as long as 10 hours. Unlike traditional lead-acid batteries, the lithium ion batteries can be recharged many more times. The number of recharges will depend on the tool being used and the amount of daily operating times. Typically the FX250 batteries will last several years, even under extreme use.
