As for the Dell DC224 battery, there are some notices that we should keep an eye to it. Its a small gadget but an indispensible part of the laptop. Though there are many replacements in the laptop accessory market, I bet that you prefer to keep the original battery. At least, I think so. I have no confidence of the replacement.

Keep the battery interface clean: It is recommended to use alcohol cleaning the battery interface monthly, as we seldom remove the battery. There might be some dust to block the connection of the interfaces. So cleaning interface can help transfer the power more effectively.

Better maintenance: Do not use battery for a long time. And meanwhile, do not leave a fully charged battery aside for a long time. Once charging the battery, you should at least use the battery once for two or three month. Of course, do not use up a clean electric lithium battery. That is harmful to your battery, too.

Cool environment: a computer works more efficiently in a cool environment. In addition to lowering ambient temperature, for the computer to do your health is also very effective. Set and optimize your power options: power management panel in Windows (Vista mobile center), you can configure and optimize the power options in detail.

Do not multiply tasks: When you use the battery to supply the power, focus on one thing. If you operate the email processor, and listen to the music, or play games, that is really wasting power. I seldom operate too many systems at the same time. Its not only slow down the browsing speed, but also wastes electricity of my DC224 battery.

Todays computers are increasingly efficient. At least two to three weeks to fully charge and discharge your battery once. Of course, if you are using a lithium battery, you will not be harassed by the memory effect. These are shared from the website and hope helpful for your battery. I still keep my Dell DC224 battery working. Though it didnt perform as well as before, I do like the original battery.
