3. Battery maintains.

We must know laptop batteries first before we choose one. There are 3 kinds of laptop batteries that we often use, including: alkaline battery, Ni-MH battery and lithium-ion battery. Alkaline battery is the most common battery in our daily life. Ni-MH battery is a kind of rechargeable battery. You can find it in retail stores in size AA. Lithium-ion battery (sometimes abbreviated Li-ion batteries) is also rechargeable. Nowadays, most laptops use Lithium-ion battery as power supply.

How to choose batteries.

If your laptop uses lithium-ion battery, the easiest way is to buy another original battery pack from the manufacture. Despite it is expensive, the quality is guaranteed and it will be full compatible with your laptop.

You can also find many OEM manufactures that supply cheap batteries. Take the http://www.sunvalleyus.com and http://www.papatek.com for instance, you can find many replacement laptop batteries.

Battery Maintains

1. For alkaline batteries, remember to take them out of the laptop after using, the alkaline liquid will damage the camera if let it out.

2. For Ni-MH batteries, fully charge/discharge battery up to 3 cycles before achieving full capacity of a new battery. Fully discharge and then fully charge the battery every two to three weeks for battery conditions. Run the device under the battery's power until it shuts down or until you get a low battery warning. This will help you reduce the memory effect greatly.

3. For Lithium-ion battery, DO NOT discharge it, it doesn't have memory effect, it will damage the battery to discharge it.

4. Remove from the device and stored in a cool, dry, clean place if the battery will not be in use for a month or longer.
