— the presence of at least one battery supplied with the corresponding tool (see "Power"). This equipment allows you to use the saw "out of the box", without worrying about finding and selecting a separate battery — unless you need to charge the complete battery before use. Note that there may be more than one complete battery — in some models up to four. However, two batteries are most common; for convenience of choice, such equipment is also placed in a separate item of this list, and its features are described in detail in the help for this item.
