Laptop battery care

by barkal_l / June 14, 2009 5:09 PM PDT

Just wanted to get a review of laptop battery care-- what I do remember is the following (please correct me if I'm wrong):

-if used primarily on AC power, leave the battery disconnected except to do a charge/discharge cycle every month-ish

-store the battery with ~50% charge (not exactly sure why)

-try to let the battery discharge at least every so often (as opposed to constantly charging when half full)

Am I missing anything pertinent?

Those statements might pertain to the old Ni-Cad batteries. Lithium-Ion are another animal.

1. Leave the battery in. In case of power failure the battery takes over. Leaving it plugged in causes no harm to the battery.

2. Store it full.

3. Cycling is not necessary.

The new Lithium-Ion batteries are a marked improvement over Ni-Cad.

Why have a battery?

When I read "leave the battery disconnected except to do a charge/discharge cycle every month-ish" I thought "Why do they have a battery at all?"

as a paper weight while he does his work on the laptop placed on his lap and the papers are going to fly away without any paperweight? :p.. jk..

But well, we'll probably know why he does that anyway.. I do leave mine out whenever I'm near a main, due to there's no in-built charging cut-off device in my laptops, so only plugged in before having to use it when there's no mains nearby.

10 tips to make your laptop battery last long

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

2. Don't play computer games, music or DVD movies - Multimedia activities drain laptop batteries.

3. Disconnect all external device like PC Card modems, Firewire, USB devices and optical drives. Use the notebook touchpad instead of an external mouse.

4. Adjust your screen brightness - Dimming your display saves battery power.

5. Tweak Windows Power Options - Choose a Laptop power scheme that turns off the notebook monitor and hard disk after 10 minutes of inactivity.

6. Decrease or mute the Laptop Speaker Volume.

7. Turn off all scheduled tasks.

8. Turn off Auto-save features in Microsoft Office and other applications.

9. If your PC has a built-in wireless card, turn it off or disable it when not in use.

10. Programs that are run from a CD or DVD can be copied to and run from the hard drive, which typically consumes less power than an optical drive.
