How do I make my Dell computer's battery life last longer?

Battery lifetime not only depends on the type of battery and quality, but also on how the battery is maintained.Here are some tips for you to make the battery life longer:

• Take out battery when laptop is running with AC power connected. Leaving fully charged battery in laptop while running on AC power will cause dell battery heat damage.
• Set up and optimize your power options. Manage the brightness at your need. Turn down the screen brightness. The LCD illumination is one of the largest power draws.
• Set it to sleep or just shut it down. Set the screen sleep and hard drive sleep times to the shortest that you can live with.
• Turn off the Software you aren’t using. Don't multitask - Quit from programs when you aren't using them instead. When you have multiple programs and you exceed the amount of RAM the machine has, it is forced to read and write Swap files on the hard drive. The more you spin the hard drive the shorter your battery will last.
• Turn off helper applications, background tasks and widgets if you don't need them (check out Microsoft's Auto runs utility)
• Cut down external devices. Turn off Wi-Fi, Bluetooth if you are not using them. Plug into Ethernet instead of using Wi-Fi, if you have the choice.Disconnect USB devices that are not being used. Don't run the DVD drive continuously.

• Cycle the battery every few weeks or after every 30 partial charges. Partially discharge and recharge (no memory effect).charge at lower voltage.
