| When buying batteries you should note the run-time and cost of the battery as compared to other brands. Another important point to observe is the manner with which the battery is to be attached, and the amount of time necessary to recharge it. You don't want to be stranded in a strange hotel room when on a business trip, with batteries you can't make sense of! Nickel Cadmium (NiCd) Batteries: These were the first rechargeable batteries manufactured for laptops. They were relatively inexpensive, had high output and versatile, because they could be used in a wide variety of products. However, NiCd batteries have now been abandoned by laptop manufacturers with the introduction of more efficient and lighter-weight batteries. Nickel metal hydride (NiMH) batteries, for example, were one better option because they had greater output, cost less, were safer and more reliable. NiMH batteries had one major drawback, though: the "memory effect." Because they had to be fully discharged before they could properly recharge, these batteries were seen as a time-consuming hassle. Older models of laptops may have these batteries. The most popular batteries for laptops is now the lithium ion (LiON). LiON batteries don't have the memory and recharging issues of NiMH batteries, and they weigh a lot less than previous types of laptop batteries. On the other hand, they are the most expensive kind of laptop batteries. You can now buy cell phones for a fraction of what they used to cost, but they can still involve a sizeable investment. You might have to save up to buy the cell phone you want, and you will need to budget your monthly income to accommodate the user fees and call charges. Another expense that should be considered is the cost of better cell phone batteries. Most phones come with a basic battery, but you might want to upgrade to a higher capacity. So, as with any purchase, the cell phone battery that costs less may not be the best quality options. Basically, you get what you're paying for. If you find a high-capacity battery at a super-low price, make sure it's not restored rather than brand new. Restored cellular phone batteries are usually made with old components, and don't work as well as new ones. If you're offered a battery at an incredibly cheap price, it's probably restore. Most people know that a digital camera battery is an essential accessory for their digital camera. Maybe you found out that your digital camera battery consumes power so quickly that you can hardly take 50 pictures before you need to recharge or replace the battery. On the other hand, some people have high-quality digital camera batteries that seem to last forever. Of course, you just need to consider your own needs and uses for your camera before you buy a digital camera battery. Digital camera batteries come in two kinds. The standard AA-size battery is extremely common. You can also get a rechargeable digital camera battery made by the camera's manufacturer. These are often called proprietary batteries. |
