How To Maintain Battery Life For Your Laptop Battery

You should not leave the charged battery dormant without usage for a long time. Make it a point to use the battery at least once in a week. Also take care so as not to discharge the Li-On battery completely.
Some producers said that their Li-ion do not memory. It is a misleading for customers. So when your laptop have relatively much power, it is better do not charge your battery. Memory effect is a process of battery content crystallization when you use the battery. It is obvious in Nickel-cadmium battery, but not in Li-ion. It will make the life of your battery shorten and reduce the use time. It is necessary to keep a nice habit. Do not charge the battery when there is much power remains.
But it is necessary to do that, because there will be a long time between the battery is active and it is sold to users. And during the waiting time, the battery is discharge naturally and when customers get their brand new laptop, the battery power is lower than they are carried out of factory. So we need to help the laptop to discharge, but not all. When there is 5% power remain, we need to plug the powerful. We need to do those 3 times to help the battery clear up their memory.
Regular defragmentation helps to arrange data more efficiently thus making the hard drive work less to access the data. The quicker the moving hard drive works lesser is the load placed on the battery. Thus, your batter can last longer. The effect is minimal, but this efficiency goes hand in glove with hard drive maintenance.
End the background processes that are not vital. Monitor the resource usage through a "Ctrl-Alt-Del' which brings up the Windows Task Manager (in Windows). If you're not on the internet, it is safe to shut down the immediate non-essential programs running in the taskbar like the antivirus and the firewall. Weed out unnecessary programs running as start-ups by launching the System Configuration Utility from Run "" Msconfig "" Tab: Startup. Uncheck the programs which you don't want to launch and reboot the computer once.
Get familiar with power management through the "Power Options' applet in the Control Panel. XP, Vista, and Windows 7 come with advanced power management features which shut off components like the monitor and/or the hard drive after specified intervals. This again depends on the chosen "Power Schemes' (for XP) in the same applet. For instance in XP, "Max Battery' under Power Schemes can be selected for maximum battery optimization.
In the Stand By mode (or sleep mode), the computer turns of the hard drive and the display but memory remains active while the CPU slows down. This draws on the battery. In contrast, hibernation mode is better because the computer saves the current state and shuts itself down completely thus saving power.
A problem more for the older Ni-MH batteries than for Li-Ion batteries on which most modern laptops run. Memory effect relates to the loss of battery charge when they are repeatedly recharged after being only partially discharged. It can be prevented by discharging the battery fully and then completely recharging it. Li-Ion batteries on the other hand have no problems with partial discharges and re-charges and complete discharge is never recommended for this type.
Regardless of how well you take care of your laptop battery, you are going to need to replace it sooner or later. It's hard to know who to buy a battery from out there on the vast Internet. My suggestion is to always buy from a company you can call and ask questions about your battery needs. Make sure the company offers a one year warranty. Ask what the return policy is. For example, perhaps you own a Dell laptop. Be sure to know which model of Dell laptop you have so you have browse through the Dell laptop batteries without getting mired down in all the selections. (Who knew there could be so many different Dell laptop batteries?) Once you get the new battery, follow the instructions carefully about charging and installing the battery. These people generally know more about batteries than you do. Take their advice.
