Replacement Batteries for Your Laptop Computer, Phone or Camera
Two important considerations when buying batteries are the cost of the battery and how long it will last, compared to other batteries. It's also important to examine how the battery has to be inserted or used with the device, as well as how long it takes to recharge. Just think of being stuck in a hotel room while traveling on business and you have batteries you can't use or don't understand!
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 were better than nickel cadmium batteries in terms of power output, cost, safety and reliability. The only problem with NiMH batteries was a memory issue, which meant they had to be completely discharged before a recharge for optimum efficacy. Some older laptops still have these kinds of 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.
Cell phones are not as expensive as they used to be, but you can still end up paying a lot for one. You might need to save for a few months to get the best phone on the market. Or you might need to watch your spending more once you start getting the bills for cell phone fees and extras. You might also need to consider the cost of 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.
A digital camera battery is probably the most important digital camera accessory. Some digital cameras can consume power at an alarming rate, providing no more than a few hours of continuous shooting time before the battery is drained. Other cameras are renowned for the long life of their digital camera battery which allows users to snap away with barely a thought to power consumption. It is important to know how you intend to use your camera and what type of battery it needs.
Two kinds of digital camera batteries are available today. The AA battery is very common, as is the rechargeable digital camera battery. Also known as proprietary batteries, these are usually made by the manufacturer.
