A typical lithium-ion cell operates with a nominal, or sustained operating, voltage of approximately 3. . Battery voltage is essentially the charge difference between the negative and positive terminals of a battery. This small decal, often referred to as the nameplate, is typically located in an area that is protected but easily visible, such as. . Power tool batteries have many different voltages, usually ranging from 12V to 60V, or even higher. Higher voltage batteries maintain more power for heavy-duty work lower voltage batteries are lighter and designed for smaller, lighter machines. For example, a 2Ah battery can supply 2 amps for one hour or 1 amp for two hours.
