Over at NECN, they provide an explanation of how electric power tools have developed, and specifically, how the improvement of batteries have led to improved power lawn tools. The article and accompanying video detail how the preconception of battery-powered electrical tools being weaker than and inferior to gas-powered lawn tools is no longer correct. It discusses how newer battery-powered power tools are more efficient in energy transferring than traditionally powered gas and electric tools thanks to evolutions in the motor department. Meanwhile, it also discusses how the batteries themselves have become smaller but with the ability to hold more energy, and that the rechargeable batteries can now achieve a charge much faster than older rechargeable batteries.
So head over to NECN and see if they can convince you that battery-powered tools are just as good in the lawn and garden as traditional gas or electrical tools.
