how to take care of a laptop battery?

Hey guys..Do u have a problem in take care of a battery that can't stay longer while using a notebook? There's some tips that i've fOund by search in others blog n my friends' advices.These tips maybe can be true, or maybe not, but u must try..hehe

1) Avoid using your laptop on plush surfaces or carpets, which prevent air from entering and leaving the unit freely. All of the laptop's components must remain cool for the longest possible lifespan, and this includes the battery.

2) Avoid using the laptop on battery power until the laptop is completely dead. When lithium-ion batteries are allowed to discharge completely, their maximum capacity can be permanently reduced.

3) Remove the battery from the laptop if the laptop is connected to a reliable power source and will remain so for an extended period. When a laptop is running on AC power, the battery is regularly "topped off" by the charger. This keeps the battery within higher temperature ranges than it should be stored at, and the repeated "top-off" charges cause wear.

4) Avoid placing the battery into long-term storage with a completely full or empty charge. If the battery will not be used for a prolonged period, place it into a zip-top plastic bag and store it in the refrigerator charged to about 40 percent of its maximum capacity.

5) Turn off Wi-Fi and BlueTooth - Most laptops have shortcut keys to instantly disable wireless networking

6) Do not expose the battery to high heat or freezing temperatures. Do not leave your battery in your car in the summer. Hot batteries discharge very quickly, and cold ones can't create as much power.

7) If you do not use your laptop for extended periods of time (a week or more), remove the battery pack from the laptop.

Ok? are you satisfy with my tips? So let's change our bad habit that can bring short life span for our lovely laptop battery..cool!
