Usually NiMH batteries last 1.5 to 2.5 hours. LiION batteries usually last 2.0 to 3.0 hours.
These are average results and the results can vary greatly depending on the configuration of your system maintenance, the room temperature and the climate that you are operating your computer in. As a general rule, your Lithium Ion battery will last longer their level of nickel metal hydride battery.
Now let's look at the usage habits of different issues to consider when your laptop battery. These processes are very similar to the way your portable stereo uses batteries dell pd946 battery. Just think how much faster your stereo eats batteries when you are playing on the CD or tape drive, unlike when playing the radio.
The more you use physical devices --- which require more electricity to operate --- the more of battery power you can expect to consume. Devices that generate a larger power drain are the hard drive, floppy drive and CD-ROM.
When the computer is able to use its physical memory resources for storing information, the team will use less battery power, since the process is mostly electrical in nature. However, when the exhaust process is using the resources available physical memory on your system, the system returns to the virtual memory to continue the process in question. Virtual memory is designed to extend system memory resources by building a memory swap file on your hard drive and then transfer the information between the hard drive and physical memory when needed. From the hard drive is a electricity hog, the use of virtual memory becomes an electricity hog by proxy.
Two other processes involving the virtual memory on your computer are computational programs and the calculation of the processes used by spreadsheet applications and database programs. Both of these items make the processor into a higher level, so that in itself is a consumer of electricity. Because both compute and calculate large quantities of information but also increase the amount of electricity that your laptop will consume.
Other physical devices that can not be left out of this discussion are audio devices and screen. As for audio devices are concerned, speakers require electricity to operate and the software that is responsible for producing the sound does it for the treatment of information. The display panel consumes electricity. In fact, the brighter the screen, the more electricity they are consuming. You can lower the brightness of the screen, thereby conserving more electricity than it can be considered possible. And when you consider the battery drain caused by video devices, do not forget the effect that graphics programs will have on your system. Video applications can have a profound effect on your electrical needs, due to their use of computers, calculations and virtual memory.
