Though laptops and desktops, both need electricity to run but laptop can run on batteries alone, if needed. Laptop Batteries are important as laptops are portable. Desktops also need small batteries to run the things like real-time clock or CMOS RAM in some cases.
What is a Laptop battery?
As you know a battery is the source of electrical energy. A laptop battery supplies power when needed by the laptop. A laptop battery is highly portable and can withstand extremes in operating conditions. There is combination of electrochemically active cells which transmit charged particles, called electrons; from one terminal of the battery to another while these ends are connected in a circuit. Primary laptop batteries are those which can be used once only and Secondary laptop batteries are those which can be recharged and can be used more than once.
Types of Laptop Batteries
Nickel-Cadmium (NiCad): These batteries were used first time in Laptops and some older laptops still use them. After each recharge laptop can work for roughly two hours and this life keeps on decreasing with each recharge based on memory effect. Total amount of available space also decreases continuously as gas bubbles form in the gas plates. To reduce this tendency, it is better to discharge the battery completely before recharging it. There is very serious fault with these batteries that is if these batteries are left to be charged for longer they can explode.
Nickel-Metal Hydride (NiMH) batteries: These laptop batteries are better than the NiCad batteries but are not efficient as required them to be. Though, they last longer between charges than their older counterparts but still shorter. They also suffer from Memory effect.
LiIon batteries: The latest Laptop Batteries are the LiIon batteries. They are most effective batteries so far for the laptops. They weigh less, do not suffer from any memory effect, have longer life spans and do not overheat when overcharged. These laptop batteries are perfect for ultra-thin notebooks as they are compact and slimmer than other batteries available. You can expect these batteries to last up to 1200 charges.
The usage of battery depends upon how computer is being used. Actually all the things like LCD display, hard disk, other drives and even the wireless internet connection also use substantial part of the battery.
When you plan to buy laptop batteries you can make a search online for the best deal available. You can always find cheap laptop batteries online for which you may have to pay more if bought from a real store.
