Cheap Batteries for Laptop Computer, Cell Phone, Digital Camera 

As you're buying batteries, it's important to find out two things: how long they last and how much they cost. You'll also want to figure out exactly how the battery works with the device, and the length of time it needs to recharge. You don't want to be on a business trip trying to figure out batteries right before a big presentation!

The first rechargeable batteries for laptops were nickel cadmium (NiCd) batteries. They didn't cost much, worked very well and could be used in many different devices. However, as more efficient and lighter batteries have come on the market, many laptop companies have discontinued using NiCd 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.

Lithium ion (LiON) batteries are the standard batteries for most laptops made today. They weigh much less than previous batteries and they don't have the memory effect of NiMH batteries. While they have many advantages, they're also more expensive than other 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 cell phones have a basic battery, but many people choose to purchase a better battery with a higher capacity. Like so many things, the cheapest option may not be the best. As the old saying goes: you get what you pay for. It's possible to find a high-capacity battery for a good price, but it could be a used, restored battery. Usually made with old parts, restored cell phone batteries don't usually function as well as new ones. If the price sounds too good, chances are you're being sold a restored cell phone battery.

The camera battery is the most important component for your digital camera. Depending on the power of your camera, the battery may only last a few hours before going dead. Some people select cameras that have digital camera batteries that last a long time. Folks with these cameras can keep shooting for days and months with no downtime. Consider how you're going to use your camera and when before you make a digital camera battery purchase.

There are two types of digital camera battery. The most widely available digital camera battery is a standard AA-size battery. The other type of digital camera battery is a rechargeable battery that is made by the manufacturer, otherwise known as a proprietary battery.
