Lithium-ion Batteries - The Way Of The Future

As an industrial maintenance mechanic for the previous twenty years, I have seen upkeep and other trades revolutionized by the introduction of cordless tools. They help save time, cash and can be used just about anywhere. Technology 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 become popular amongst 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, more run time, and a lighter tool. The improvement of lithium-ion batteries for the cordless tool industry addresses all 3 of these customer needs. Lithium-ion batteries provide 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 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 technology, producers can pack more energy in a battery pack that is the same size/weight as the NiCad or NiMH or match the exact same energy 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 % 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 provide 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 technologies. This assists energy delivery remain constant over the life of the charge. We all know what occurs to a cordless tool when the battery starts to wind down.

It loses much of its power.The energy 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 much better ergonomic design. With the battery not extending into the handle of the tool, manufacturers can make a much more comfy 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 much more years but like cars, older models are eventually retired to make way for the new. Go to [] for more cordless drill info.
