Cordless Power Tool Battery- Ni-cd- Ni-Mh or Li-ion?

There is a burning desire for all of us in the trades to swap our power cords for a cordless power tool. Battery life and its power band must meet our jobsite needs, if the purchase is to improve our productivity and enjoyment of our craft. With all the innovations in cordless battery pack technology how does one make the right purchase .. without paying for what you don't need?

Lithium Ion Power Tools

We've all experience the frustration of running out of power, unable to find a freshly charged cordless battery pack. We all know that the minute we take the cordless drill outside it loses half of its power. And we all know that muscle fatigue is a big issue when we get into the larger voltage cordless tools.. all of which sometimes convinces us to return to the corded model. But are there better answers?

Lithium Ion Power Tools

Ni-Cd: This is the old time favourite of cordless tool batteries. It has a long history of reliable performance, even in cold weather applications. Batteries are typically less expensive than other alternatives. Some have suggested that these batteries suffer from "memory affect problems" but some manufacturers like DeWalt and Miwaukee dispute this with their new professional quality models.

As a more environmentally conscious population, we have concerns in using cadmium based batteries, and so there is consumer resistance in supporting this option in light of more environmentally friendly Nickel Metal-hydride models.

Nickel Metal-hydride: These are kind of what we would think of as a second generation cordless battery pack. It entered the market with promises of more power and lighter weight, both of which it achieved but at a price! The cell design of a metal hydride battery generates more heat in both the dissipation and charging cycle. In fact it generates so much heat that the charger typically includes a fan to cool the unit during re-charging. This added heat creates a battery that doesn't survive as many charging cycles as its old cadmium cousin, suggesting higher replacement cost leading to less consumer satisfaction.

Of the three common types of cordless batteries metal-hydride are also the one least able to survive fluctuations in temperature. In cold weather it loses significant power, thus if you are an all weather framer, although the lower weight may appeal to you, it is not the battery pack to purchase. On the other hand if your use is more related to indoor cabinetry it may be the perfect light weight option.

Li-ion: This is going to be the battery to watch. Although it has not been on the market for long, initial experience would suggest that it will be the best of the three in cold weather operation. It is also the lightest of the three in direct comparison of "size to voltage".

So what's the down side? Cost. Li-ion cordless batteries are the most expensive of the lot. For long life usage, li-ion batteries must have electronic circuitry on board to balance the charging and discharging load across all battery cells. They also require longer re-charge times to allow for individual cell rebalancing, as a means for extending the life of your battery pack, thus if you are constantly draining and recharge over short periods of time a Ni-cd may be a better choice. Time will tell if this technology will have long term reliability and find solutions to the longer re-charge issues.

So what are the trade offs you should consider? A balance between weight and power is always the first and foremost consideration. Don't buy a 7 pound Big Bertha if all you are going to do is predrill 1/8" holes and don't worry about cold weather performance if you are always working in a heated shop. Recharging speed won't be a big issue if you're the casual user and of course we'd all like to buy with a good environmental conscious.

Find out as well, what is the one rating on cordless batteries that will allow you to compare power output on two identical voltage rated batteries. Visit our website http://www.woodsTheBest.com.

Lithium-Ion Batteries - Ebike Technology

The secret to the energy-efficiency and convenience of the electric bicycle is the rechargeable battery that powers the electric motor, which eases pedaling and accounts for the bicycle's maximum speed and range.

Lithium Ion Power Tools

The state-of-the-art in electric bicycle battery technology is the lithium ion battery. The use of these batteries in electric bicycles is a new use of an established technology. Lithium ion batteries have powered consumer electronic devices for years. In electric bikes, these batteries are lightweight and easy to recharge.

Lithium Ion Power Tools

Early work on lithium battery technology began as early as 1912, but it was the 1970s before the first lithium batteries were available for purchase. Those early batteries could not be recharged. By the 1980s, work had begun on developing rechargeable lithium batteries. Consumer electronics giant Sony pioneered the first commercially available rechargeable lithium ion (or Li-ion) battery. Today, this battery technology has become widely available, with electric bicycles being the newest application.

The rechargeable lithium ion batteries in electric bicycles enables these vehicles to travel at speeds of up to 20 mph for a range as high as 40 miles. The batteries themselves are low-maintenance and can be recharged for only pennies a day. This makes an electric bicycle with a lithium ion battery a real bargain in a time of rising gasoline prices.

Many people like electric bicycles because they help facilitate a "greener" lifestyle by traveling on electricity instead of fossil fuels. The environmentally friendly nature of electric bicycles extends to the battery, as well. Lithium ion batteries cause less pollution and environmental damage when disposed of than their lead- or cadmium-based counterparts. The U.S. government classifies these batteries as non-hazardous and therefore, safe to dispose of in standard solid waste facilities. For recycling purposes, however, a used lithium ion battery pack still contains usable materials. This means that recycling your used battery instead of disposing it makes them even safer for the environment!

Overall, this form of battery has a life of about 15,000 miles before requiring replacement. This means it can take about 500 charges over its lifetime. Although the more expensive than other types of batteries used in electric bicycles, it is far less expensive in the long term than frequent trips to the fuel pump to fill the car's gas tank.

Lithium ion batteries can be recharged using a standard electric outlet. Because these batteries weigh less than those made from other materials, they are far more portable. This also means that they don't greatly add weight to the bicycle. On average, most li-ion batteries are 70 percent lighter and about 50 percent smaller than cheaper, bulkier batteries used in some electric bicycles.

Power Tool Battery Directory - NiCad, NiMH, and Li-Ion Batteries in Your Cordless Tools

It can be easy to dismiss the importance of a high-quality battery in the functioning of your cordless tools. As it turns out, however, a good battery is just as essential to a cordless tool as a healthy armature or motor. Battery technology has significantly advanced since the introduction of cordless power tools; since the development of the Nickel Cadmium (NiCad), power tool batteries have evolved from NiCad to Nickel Metal Hydride (NiMH), and most recently to Lithium Ion (Li-Ion) technology.

Lithium Ion Power Tools

Nickel Cadmium batteries were the first on the market for cordless power tools and though the technology is older, it is still very reliable. NiCads are less sensitive to adverse temperatures and have a high recharge cycle, meaning they can be charged and recharged repeatedly for a long period of time. NiCads are also less expensive than NiMH and Li-Ion batteries. On the down-side, however, NiCads tend to suffer from battery memory effect. This occurs when a battery can no longer accept a complete charge because it had been repeatedly charged without first being fully depleted. It seems the battery "remembers" how much energy it has discharged, and only wants to accept back that much energy from charger. The element Cadmium is highly toxic making it the most harmful battery to the environment. The NiCad's negative effects on the environment, in fact, cause them to be heavily taxed outside the U.S.A. As a result, many European vendors won't sell NiCad batteries.

Lithium Ion Power Tools

Nickel Metal Hydride batteries run on a higher amperage than NiCads, because of this, they also have a longer run-time. NiMHs are lighter than NiCads but they are far more sensitive to hot and cold temperatures, in fact, NiMH can't work in below freezing temperatures (32 degrees Fahrenheit and below) and they degrade very quickly in intensely high temperatures (105 degrees Fahrenheit an up). Although the NiMH has a longer run-time than the NiCad it doesn't accept as many charges. NiCad and NiMH batteries do have very similar overall lifespans but NiMH has a larger energy storage capacity.

Lithium Ion batteries have a higher energy density than most other rechargeable batteries. A high energy density means that the Lithium Ion has a superior energy to weight ratio storing more energy for their size than most other batteries. Li-Ions have a very slow self-discharge rate meaning they retain their charge for much longer. Most rechargeable batteries significantly deplete as they are disengaged, the slow rate of charge-loss in Li-Ions, however, allows them to maintain most of their charge for longer periods, even on a shelf in your shop or garage.

There are many benefits to working with Lithium Ion batteries from their light-weight, to their long run-time. Li-Ions maintain their charge for much longer and have continuous max power throughout their energy discharge cycle. Other batteries consistently lose power as you work. Li-Ions are light-weight, and have a huge storage capacity, this means you now have a lighter, more efficient and powerful battery without the bulk. Lithium Ion batteries are by a landslide the least detrimental to our environment, and for many reasons they are the favorite of most craftsmen.

There are, however, some disadvantages to Lithium Ion batteries. Li-Ions are a bit more expensive. The complexities of production (in circuitry) accounts for this price difference. Each Li-Ion also requires a specifically built charger to accommodate that type of battery; this means that chargers are more expensive as well, and aren't universal to all types of Li-Ion batteries. The Li-Ion has a built-in chip that protects the battery from over and undercharging, and ensures it has a longer life. This computer chip, however, doesn't allow the battery to continue accepting charge once its energy level has dropped below a certain point. Once this happens the battery is essentially dead. Li-Ions also rely on this circuit to stay cool. Since Li-Ions lose charge so slowly, and the battery and charger communicate so well together, it's fairly simple to keep Lithium Ions temperate and at a safe charge level.

Remember, the quality of the battery you use is just as important as the quality of your power tool. The battery gives the right amounts of energy and finesse to your tools and their working parts.
