LAPTOP BATTERY OPTIMIZING
Laptop manufacturer's specifications displayed how long battery life, although it is written may be between two and two and a half hours, the reality is often less than it. If the battery life is less than the laptop manufacturer's specifications, it can be caused by various factors.
Certainly, more work is done using a laptop; the more resources will be used, as an example of multitasking will give a heavy burden to the CPU, memory and hard drive, which eventually will consume the battery. There are several steps that can be done to maximize the use of battery power.

Make sure your laptop can operated between 2.5 to 4 hours on a single battery charge. If the battery can not provide standard operating time, then maybe need replaced, depending on how the type and condition of the battery. If the battery is functioning properly, you may need to buy a second battery or even add an extended battery universal, depending on the desired operating time in a one-time charge.
Batteries have limited charge cycles so use only the battery if absolutely necessary.
Use the battery as low as possible before filling it again.
A new battery comes with conditions no filled and should be fully charged before use. We recommend that the full and empty the contents of the battery two to four times in order to achieve maximum capacity.
If settings are correct but the laptop battery is still not able to provide sufficient amount of operating time, there is a possibility due to the "Memory Effect" that is battery will remember of the last capacity before it refilled, it should be when will recharge the battery make sure the battery is empty, and make sure the battery already full before unplugging the charger. Type of battery that has a "Memory Effect" such as, Nickel Cadmium (NiCad) and Nickel Metal Hybrid (NiMH), both of which type of laptop battery longest in the market, while Lithium Ion is the newest type of battery that does not have a problem "Memory Effect".
