The Capacity of Laptop Batteries Explained
Laptop batteries are rated by, Voltage (V) and Milliamp-hours (mAh). Voltage is the rate at which energy is drawn from the battery and Milliamp-hours represents the capacity of the battery. The Milliamp-hour rating corresponds to the run time of the battery. A battery with a high Milliamp-hour rating, has a relatively longer run time than a battery with a low Milliamp-hour rating.
The Most Common Chemistries Used in Laptop Batteries
The most common chemistries used in laptop batteries are: NiCad (Nickel Cadmium) - This is the oldest technology and is the least commonly used nowadays. NiCad batteries are prone to the "Memory effect" and are heavier than the newer technologies. NiCad is not environmentally friendly chemistry as it contains heavy metals, which cannot be disposed of in landfill sites. Most manufacturers have stopped producing batteries of this type chemistry. As an end user it will be increasingly difficult to source these batteries. The best alternative is external battery packs. This is an external battery, with run times of up-to 10hours and is compatible with most manufacturers.

Recycling Dell Electronics Products
Much too many peoples surprise, recycling of electronic products has been around since these, now, indispensible products have been in existence. For much of that time the recycling process was more oriented toward greed with the recovery of precious metals like gold and silver being the main goal. Oddly, electronics manufacturers have been right on top of the issue, if not wanting on getting the message out that they are on top of the issue.
The Most Common Laptop Battery Problems
Laptop batteries can often be expensive because the laptop manufacturer is the only one who makes a battery to fit their particular laptop. This is done so the manufacturer will have control of the market when you need a new battery. Often this is done to encourage you to buy a new laptop instead of replacing the battery. In many cases there is little difference in the price, which is what the manufacturer intended.

Battery Lights
Battery Operated Lights.
Battery operated lights have come a long way. Many people believe batteries are a fairly new invention. Did you know the first battery was invented in 1800? Or that the first flashlight was made in 1898? Now, those batteries were not the kind you and I think of today. They were actually quite unstable and not very reliable. Lets take a look at how battery lights came to be.
History of Lights.
Light has been used by man for a long time. Light gives our plants energy, which in turn feeds us. We also get vitamin D from light. Before modern scientific times, light was something that was thought just to be seen by our eyes. By the 1500's and 1600's though, telescopes, microscopes and new lenses were being invented. We could then see things on a smaller scope. Isaac Newton discovered the color spectrum in 1666. Soon the electric light bulb was invented by Thomas Edison. Light is useful in many aspects of our life. It helps us to see at night, directs traffic, helps us see while we read and gives us light for photography. It's also useful in areas of health such as giving our food vitamin A, helping plants to grow and fights disease. We use light for everything now a days.
History of Batteries.
Batteries came on the scene around 1800. Batteries were invented by an Italian, Volta. They were rather unstable because they were wet cell batteries. For that reason, wet cell batteries were used to power stationary devices. In 1859, the first rechargeable battery was invented by Gaston Plante. Finally a dry cell battery was invented in 1887 by Carl Gassner that was much safer to use and portable. It changed the liquid material into a paste to make it more stable. In 1955, alkaline batteries were introduced to the public. Up until then, batteries had a short life and were very expensive.
Battery Lights, Together.
Batteries and lights came together. The first battery operated lights were flashlights. Today though, we have battery operated lights. Many Christmas tree lights are battery powered. It allows for mobility of your tree. Also, many people use battery lights for weddings. Battery operated lights are popular for outdoor weddings where electrical outlets are unavailable. You can also string the battery lights through the bouquets to make them shine at an evening ceremony. Actually, battery lights are popular for almost any occasion. The flexibility of battery operated lights allows them to be used almost anywhere.
LED Lights.
LED lights are becoming very popular. LED stands for light emitting diode. They use very little energy and put out much less heat. This attracts many people trying to save on their electric bill, especially with rising energy costs. LED lights are more expensive, right now, but the total cost of ownership is far less then the average incandescent light. LED lights produce more light than the average bulb, per watt. LED lights are the way of the future.
