As an industrial upkeep mechanic for the past twenty years, I have seen upkeep and other trades revolutionized by the introduction of cordless tools. They assist save time, cash and can be used just about anywhere. Technologies has come alomg way because the early days of cordless tools. Larger voltages have resulted in much more power and longer run occasions from batteries have helped the tools turn out to be popular among tradesmen.
1 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 previous. The tool manufacturers 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 industry addresses all three of these consumer 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 previous, many of the NiCad and NiMH batteries had to extend up into the handle 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 development of lithium-iom technologies, manufacturers can pack more energy 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 provide more run time per charge than NiCad.The highest capacity for lithium-ion batteries is 3. Ah. This represents a 25 % improve of the NiCad at 2.4 Ah. The NiMH highest rated capacity is 3.5 Ah. The lithium-ion may not deliver a better run time than the NiMH, but the lithium-ion battery will deliver much better total performance more than the life of the battery than NiCad and NiMH.The results are plainly noticed 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 technology. This assists energy delivery remain constant more than the life of the charge. We all know what happens to a cordless tool when the battery begins to wind down.
It loses a lot of its power.The power loss at the finish of the charge is drastically decreased in lithium-ion batteries. The lithium-ion battery delivers much better total overall performance over the life of the battery than NiCad and NiMH. Another advantage of lithium-ion batteries is that cordless energy tools have a much better ergonomic design. With the battery not extending into the deal with of the tool, producers can make a much more comfortable grip for their consumers to improve the use of the tool. Lithium-ion batteries are the way of the future in cordless tools. NiCad and NiMH will be around for several more years but like vehicles, older models are ultimately retired to make way for the new.
