Lithium-ion Batteries - The Way Of The Future

As an industrial upkeep mechanic for the past twenty years, I have seen maintenance and other trades revolutionized by the introduction of cordless tools. They assist save time, cash and can be used just about anyplace. Technologies has come alomg way since the early days of cordless tools. Bigger voltages have resulted in more energy and longer run times from batteries have helped the tools turn out to be popular among tradesmen.

One of the only knocks against cordless tools has been the weight. The typical 18 volt cordless drill has weighed up to six pounds in the past. The tool producers have listened to the tradesman who want more energy, much more run time, and a lighter tool. The improvement of lithium-ion batteries for the cordless tool business addresses all three of these consumer requirements. Lithium-ion batteries provide 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 general weight for the battery and tool. With the development of lithium-iom technologies, producers can pack more energy in a battery pack that is the same size/weight as the NiCad or NiMH or fit the 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 improve of the NiCad at 2.4 Ah. The NiMH highest rated capacity is 3.5 Ah. The lithium-ion may not deliver a much better run time than the NiMH, but the lithium-ion battery will deliver 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 more than the cycle life of the lithium-ion battery. The power delivery curve is steady compared to the older technologies. This assists power delivery stay continuous over the life of the charge. We all know what happens to a cordless tool when the battery starts to wind down.

It loses much of its energy.The energy loss at the end of the charge is drastically decreased in lithium-ion batteries. The lithium-ion battery delivers better total overall performance over the life of the battery than NiCad and NiMH. Another benefit of lithium-ion batteries is that cordless power tools have a better ergonomic design. With the battery not extending into the handle of the tool, producers can make a much 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 around for a number of more years but like vehicles, older models are ultimately retired to make way for the new. Go to [] for much more cordless drill information.
