Hercules: An All Time Hero! A national hero of the Dorians, Hercules is a purely greek hero who represents human power to tame nature - a power that is nonetheless combined with benevolence and justice, and is thus able to free humankind from its torments. The hero was the son of Zeus and Alcmene.
The new Hercules cordless tools also use 20V lithium batteries similar to the Earthquake XT 20V batteries but are not the same ones meaning they arenât cross compatible. For more info on the Earthquake XT 20V cordless power tools also sold by Harbor Freight, click here. All three Hercules 20V tools are sold as kits and include one 2.5ah battery, charger and hard case. Additional batteries are sold separately and they also offer 5.0 ah batteries.
