As an industrial maintenance mechanic for the past twenty years, I have noticed maintenance and other trades revolutionized by the introduction of cordless tools. They help save time, money and can be used just about anyplace. Technologies has come alomg way since the early days of cordless tools. Bigger voltages have resulted in much more power and longer run occasions from batteries have helped the tools become well-liked among tradesmen.
One of the only knocks against cordless tools has been the weight. The average 18 volt cordless drill has weighed up to six pounds in the past. The tool producers have listened to the tradesman who want more power, much more run time, and a lighter tool. The development of lithium-ion batteries for the cordless tool business addresses all 3 of these customer requirements. Lithium-ion batteries offer a reduction in cordless battery weight of 25-40 % and a total tool weight of up to 25 %. In the past, numerous of the NiCad and NiMH batteries had to extend up into the deal with of tools such as cordless drills, reciprocating saws, and circular saws. This all translated into much more overall weight for the battery and tool. With the improvement of lithium-iom technology, producers can pack more power in a battery pack that is the exact same size/weight as the NiCad or NiMH or fit the exact same power as the NiCad or NiMH in a smaller battery pack.
Lithium-ion batteries can also deliver more run time per charge than NiCad.The highest capacity for lithium-ion batteries is 3. Ah. This represents a 25 percent increase of the NiCad at 2.4 Ah. The NiMH highest rated capacity is 3.5 Ah. The lithium-ion might not deliver a much better run time than the NiMH, but the lithium-ion battery will deliver much better total performance over the life of the battery than NiCad and NiMH.The results are plainly seen in the the energy delivery curve over the cycle life of the lithium-ion battery. The energy delivery curve is steady compared to the older technologies. This helps power delivery stay constant over the life of the charge. We all know what occurs to a cordless tool when the battery begins to wind down.
It loses much of its power.The power loss at the finish of the charge is drastically reduced in lithium-ion batteries. The lithium-ion battery delivers much better total performance over the life of the battery than NiCad and NiMH. An additional advantage of lithium-ion batteries is that cordless power tools have a better ergonomic design. With the battery not extending into the deal with of the tool, manufacturers can make a more comfortable grip for their customers to improve the use of the tool. Lithium-ion batteries are the way of the future in cordless tools. NiCad and NiMH will be about for several much more years but like vehicles, older models are ultimately retired to make way for the new.
