Laptop Batteries
There are actually three distinct notebook battery types on the market today. Nickel Cadmium - NiCd batteries were actually the first rechargeable laptop batteries ever. You won't find Nickel Cadmium batteries being used anymore, due to them being heavier and not as efficient as the newer laptop batteries.
Nickel Metal Hydride - NiMH batteries can still be found all over the place -- particularly for older model laptops. The rechargeable NiMH laptop battery was a big step up for notebook technology mostly in part because they were more reliable than the NiCd batteries, and they had an even higher output. The NiMH battery was also cheaper to produce, and safer to use.
Basically, if you don't fully discharge the battery, it can remember this and leave you with a less than perfect battery output.
Lithium Ion - LiON batteries are now used in most new laptops. Unlike the NiMH battery, LiON laptop batteries have no memory effect. LiON batteries are also lighter than both NiCd and NiMH notebook batteries. You are probably wondering which type of battery to get. If you cannot afford a LiON battery or your notebook is not compatible with one, then getting a NiMH battery is the next best thing.
After knowing the type of battery, I will give tips on How To Buy A Laptop Battery Replacement.
As we all know, battery is the most essential part of a laptop. Usually one laptop only has one type battery. There are two ways for you to find out the type of your laptop battery.
Search the laptop brand and model number on the internet, and its manufacturer's website is better, so as to find out its battery type.
Secondly, buy a battery with longest life and life span that available for your laptop.
Long battery life means that you don't need to charge it often, and long life span means that you don't need to replace your laptop battery again in a short time. Here the third-party brands mean the brands different from the brand of your laptop. As far as I am concerned, a lot of people buy a laptop battery with the same brand of their laptops. Some batteries made by the third-party have same quality with the original manufacturers' batteries; however, their price is much lower. Batteries made by the third-party have longer warranty. Now after all these preparation, it is time for you to buy a good battery for your laptop.
