Cordless tools have finally reached the point where they can deliver power equal to their corded counterparts. This is due to advances in cordless battery technology. Early cordless batteries were weak and needed frequent recharging. Cordless battery development has improved to increase both the battery life and the power delivered. Many these power tools are now the equal of the same device run off a cord.
There is no denying that cordless power tools are convenient. They are much easier to handle without towing a long extension cord behind them. The cordless nature of these devices allows workers to take them almost anywhere on the job site. Powered by modular rechargeable battery packs, these power tool weights compare favorably to the corded version. Cordless power tools can be clipped to tool belts for easy carrying.
The cordless type is also much safer than those running on live current. Because no extension cord is needed, cordless units can not trip other workers. There is no chance of accidentally cutting through one's power cord or that of another worker. The enclosed charge of the cordless battery means significantly reduced opportunities for electric shock. When using cordless power tools, the chance for an electrical accident is dramatically reduced.
Cordless power tools have their own individual needs, however. The cordless batteries need periodic recharging. The harder and longer a cordless device is used, the more frequently the battery must be recharged. For extended projects, keep several charged batteries on hand for each cordless tool. It is much less expensive for a worker to swap out a used battery for a charged one. Cordless power tool batteries take several hours to overnight to recharge fully. The construction crew chief must not forget to do this every night.
If you own tools that are cordless, read the battery care instructions. Most cordless items lose power primarily, indicating that recharging is needed. Cordless batteries typically trickle-charge over multiple hours, although faster recharging units may be available. Some cordless batteries should be stored while connected to the recharge. Others should not be during extended periods of storage. Get the most of your cordless power tools by taking care of the batteries.
Cordless drills, saws, and even yard care tools are available. Cordless units are lightweight and easy to use. Keep your batteries appropriately charged and stored, and your cordless tools will give you excellent service for a long time.
