5 Tips to Extend Your Laptop Battery's Life:

• Keep your laptop battery cool. Batteries degrade more quickly when they're hot. That means you should keep vents clear - don't put your laptop on a fluffy pillow or a cushioned surface that will cover vents and trap heat
• Don't pack your laptop away in a backpack or other enclosed space when the battery is still warm, trapping the heat. A battery that's frequently hot to the touch will lose life a lot faster than a battery that isn't constantly being stressed. Worst of all: If your laptop crashes or refuses to shut off properly, the battery can get extremely hot when packed away in your bag. Check it to make sure it hasn't gotten dangerously hot while stowed away over the weekend
• Don't charge your laptop constantly. If you only occasionally take your laptop away from a power outlet, but leave it plugged in to charge 24/7, you're leaving your laptop in a state of perpetual charge at the 100% point - and that is bad for the battery's long-time health
• If you tend to use your laptop mainly at your desk, exercise your laptop battery by running it down and recharging it once or (even better) twice a month
• Alternately, you might want to physically remove the laptop battery if you're using the laptop at your desk for long stretches of time. If you do remove it, don't store it in a fully charged or depleted state. It's best to store it in the middle - between 40 and 50 percent of full charge

How to Test a Laptop Battery?

Testing a laptop battery allows you to determine if it has any remaining charge. The best way to test a battery is to connect it to a laptop and turn the unit on. However, there are several other ways to determine if your laptop battery has any charge.

• Test your laptop battery with a test light. Check the test light first to make sure it works. Connect the light to a metal ground source. Check the test light on a battery that you know works. If the test light glows, it's good. Place the light's test end into the battery's positive port. If the light glows, your battery is good.
• Check your laptop battery with a battery tester. Put one end of the tester in the battery's positive port, and the other in a negative port. The tester will read how much life is in the battery, if any.
• Hook your laptop battery up to a multimeter. Follow the process in Step 2 to connect the meter and determine how much charge is left in the battery. Most multimeters are electronic, but some have gauges that move to a certain point.
• Place the laptop battery on a battery charger. These are mostly used for cars. Battery chargers generally indicate if a battery is good, bad or needs a charge.

How to Recondition a Laptop Battery?

Like all rechargeable battery packs, laptop batteries eventually lose their ability to hold a full charge. Although it's not possible to make a battery pack perform like new again (unless the cells are replaced), it is possible to improve cell performance by reconditioning or calibrating some laptop battery packs.

• Insert the battery into the laptop. Plug the laptop in and allow the battery to fully charge (the battery indicator light turns off on most laptops when the battery is completely charged). Restart the computer.
• Disable hibernation temporarily. In Windows XP for example, click "Start" in the task bar, then click on "Control Panel," and then "Power Options." Select the "Hibernate" tab then uncheck "Enable Hibernation." Click "OK" to save the settings.
• Discharge the battery. In Windows XP for example, click on "Control Panel," "Performance and Maintenance," "Power Options," and then "Power Schemes." Make a note of the settings under the "Plugged In" and "Running on Batteries" columns so you can reset them later.
• Set all six options to "Never" from the drop-down lists. Click "OK" to save the settings and disable power management.
• Unplug the laptop, but do not turn it off. Run the laptop until the battery is completely discharged (the Power/Standby light will blink) and the laptop shuts down.
• Plug the laptop back in, allow it to fully charge again, then restart the computer. Enable hibernation (reverse step two), then enter your original performance settings in "Power Schemes" (see step three).
