If you were to look at most of your high end electrical devices such as laptop, personal digital assistant, cell phone, MP3 player etc, most probably it will be powered by a lithium based battery.
There are several important aspects to think about when you are buying a laptop computer. One of these aspects is the laptop battery life. Because laptop computers are so mobile, you will not always have electrical power. I used mine every night with my with wife as she was driving to law school. I can tell you that there is nothing more annoying than working on a project and having your laptop tell you that you have five minutes of battery power left. I have found that lithium mines ontario batteries work better than the Nickel Cadmium batteries. I have also found that you can actually 'train' your batter to have a good memory effect.
A few years ago mobile phones used Nickel-Cadmium batteries that had a "memory" so to speak. What this means is that if you let you battery get to 50% of charge capacity and then charged it it would start to think that at 50% capacity it was totally empty. Many of us remember how quickly cell phone batteries seemed to die with the (Ni-Cad) battery. If you have a Nickel-Cadmium or a Nickel-Metal Hydride battery, make sure you let it run all the way down before charging to give it the correct memory parameters. Lithium mines Ontario Ion batteries have no "memory effect" whatsoever. This means you can charge your phone when the battery is at 80% or when it is completely dead without harming the battery.
The Makita BDF452HW cordless drill comes with an 18-V lithium-ion battery and it charges in only 15 minutes. That's a much quicker charge time than almost any other drill you can find. Along with the quick-charge, the battery life is also very good so you don't really have to worry too much about it dying on you.
This cordless driver comparison showed that Lithium-ion batteries hold a charge a lot longer than a nicad battery. A fully charged Lithium-ion batteries can hold a charge for up to a year. My cordless driver comparison did clarify to me that when comparing drivers its important to compare cordless drivers with similar power. Power wise a 12 volt Nicad battery has the same power as a 12 volt Lithium battery stocks ion battery and a 18 volt nicad battery has the same power as a 18 volt Li-ion battery. So don't expect the same torque found in a 18 volt nicad cordless drver from a new 12 volt li-ion cordless driver.
The NiMH battery is much friendlier to the environment than the NiCd battery. It showed up in the market after the NiCd. The two types of batteries share the same physical packaging so that you can use a NiMH replacement battery for you NiCd cordless tool. NiMH battery can hold more charges and last longer than the NiCd battery so it costs more. But if you can find a NiMH replacement battery, it is a better deal despite the higher price.
Another benefit of the lithium-ion Toshiba laptop battery is that it doesn't have any memory. This refers to an effect that many rechargeable batteries have. Each time they are charged and drained, they "remember" how far that charging goes, and how far down they are drained. If the battery doesn't get fully drained every time it gets used, it starts charging only to that level. For example, if it only gets drained 90% each time it gets used, after some time it only charges to 90%. Eventually, the effective use life of the battery gets down to the point that it can't be used without being constantly hooked into a charger. But li-ion laptop batteries don't have that problem. They do not need to be fully drained to be recharged and they will always empty and charge to their full extent. Report this page
