There are two ratings on a battery, Voltage (V) and Milliamp-hours (mAh). Voltage is the rate at which energy is drawn from a battery. Milliamp-hours represents the capacity of the battery. Here are some questions that might pop-up in your mind regarding your Laptop battery and answers to them:
For years scientist have been looking for cheaper and safer Lithium-ion batteries, but some researchers from Shanghai’s Fudan University have now made some progress in an area that has previously proven to be particularly tricky for battery makers. They’ve managed to create an aqueous lithium-ion battery that substitutes most of the oxygen in the battery [...]
The general performance characteristics of Li-ion batteries are outlined in table below. As indicated in the table, Li-ion batteries have a high voltage, typically operating in the range of 2.5 to 4.2 V, approximately three times that of Ni-Cd or Ni-MH. As such, fewer cells are required for a battery of a given voltage. Li-ion [...]
Sanyo Electric Company has announced the completion of their new factory in Hyogo, Japan, which will be the new production facility for litihum-ion rechargeable batteries made for eco-friendly vehicles. With almost 13-billion yen invested into the 43,000 sq m plant, Sanyo will be able to produce one million cells per month to start and will [...]
Lithium-ion (Li-ion) batteries are comprised of cells that employ lithium intercalation compounds as the positive and negative materials. As a battery is cycled, lithium ions (Li+) exchange between the positive and negative electrodes. They are also referred to as rockingchair batteries as the lithium ions “rock” back and forth between the positive and negative electrodes [...]
Lithium-ion battery Life Span Lithium-ion battery packs are expensive, so if you want to make yours to last longer, here are some things to keep in mind: Lithium ion chemistry prefers partial discharge to deep discharge, so it’s best to avoid taking the battery all the way down to zero. Since lithium-ion chemistry does not have a [...]
Inside a Lithium-ion Battery Pack and Cell Lithium-ion battery packs come in all shapes and sizes, but they all look about the same on the inside. If you were to take apart a laptop battery pack (something which is not recommended because of the possibility of shorting out a battery and starting a fire) you [...]
Lithium-ion batteries are incredibly popular these days. You can find them in laptops, PDAs, cell phones and iPods. They’re some of the most energetic rechargeable batteries available. Lithium-ion batteries have also been in the news lately, because these batteries have the ability to burst into flames occasionally. It’s not very common — just two or [...]
In the past 20 years, power tool manufacturers have come very long way in making cordless tools smaller, lighter, more powerful and last but not least more durable. Much of this focus has been on the power tool batteries that power these tools naturally, experimenting with new technologies. By understanding the advantages and disadvantages of each [...]
Your camcorder battery has to be properly used and well maintained so that you can enjoy a maximum long life span of it. In fact, when you take good care of your battery, its long life is guaranteed. You should note, that the battery life is shorter in a cold environment. Therefore if you are [...]
