For power tools, battery technology seems to be making inroads and moving an increasing number of products into the realm of emissions-free, cordless technology. Yard tools have been understandably delayed, since the bettery power and sustained use periods make it difficult to transition over to a reliable, rechargeable solution. Black & Decker is still at the forefront, however, and has released a new 18V String Trimmer & Edger (Model NST2018) that eliminates gas in favor of NiCd batteries. While clearly more convenient than a corded solution, the real question is whether or not the power and usability will cause anyone not paranoid about emissions to switch to the new technology. Our guess is that it may take a few more product iterations before mainstream users pick up these new cordless tools over their more traditional gas-powered counterparts.

Battery technology is creating a seemingly endless sea of new and innovative products that are quickly placing emissions-free, cordless technology into the hands of consumers, where previously gas was the only available option. Yard tools are tougher than your typical cordless power tool because they typically demand sustained power over longer periods of time than a drill gun or even a product like a finish nailer. Because of this, we look favorably on products such as the new 18V 22″ Cordless Hedgehog Hedge Trimmer that uses NiCd batteries in place of gas or dragging a cord. Those who are adamantly against adding emissions to the atmosphere will jump at any new cordless option, but the real test is whether a tool has mass market appeal. At this point, most products, including this one will likely take a few more years and product iterations before mainstream users dump their gas products for new cordless tools.
