I just got a new battery for my laptop, and yet it still burns through very quickly, its a brand new battery.

what is wrong?

Do you leave your laptop plugged in all the time? If you keep charging a lithium ion battery when it doesn't need to be charged it becomes weaker and weaker. Just charge it when its at like 20%. Also if you keep running intensive programs of course its going to drain, also lowering screen brightness might help, or to changing power saving settings.

Another thing, my battery keeps changing the time of left drastically, it went from 2 hours to 3 hours then o 5 hours

Laptop batteries have always been stupid.
Get a netbook or leave it plugged in 24/7 like me.

Have they still not placed a fucking circuit in a laptop so that it switches off the battery at full charge? The fuck? My 3ds can do that but not a laptop which has been in works for years. You would think they would have done that by now.

let me share something about the laptop battery, the actual life of a laptop battery will vary with computer usage habits. For most users, it is not uncommon to experience differences in battery life, of anywhere from just under one hour to over two hours in each sitting. If you are experiencing shorter battery life cycles, say 10 to 15 minutes, it may not yet be time to order that new battery.

There are several factors to take into consideration when determining if the time has come to replace your battery. This information may also apply to that new battery that you have recently purchased, that has been giving you fits. The two primary things to consider when troubleshooting battery problems is Usage Habits and Battery Memory. We will cover both in their complexities in just a moment, but first, let us take a look at what you should expect from your battery's life cycle.

NiMH batteries usually last 1.5 to 2.5 hours.
LiION batteries usually last 2.0 to 3.0 hours.

These are average results and the results will vary greatly depending on your system's conservation settings, the temperature of the room and the climate that you are operating your computer in. As a general rule, your Lithium Ion battery will last much longer than your standard Nickel Metal Hydride battery.

Now let's take a look at the various usage habits to consider when troubleshooting your laptop's battery. These processes are very similar to the way that your portable stereo uses batteries ... just think how much faster your stereo eats batteries when you are playing the CD or the tape deck, as opposed to when you are just playing the radio.

The more you use physical devices --- which require more electricity to operate --- the more of the battery's power you can expect to consume. The devices that create a larger power drain are the hard drive, the floppy drive and the CD-ROM.

When the computer is able to use its physical memory resources to store information, the computer will use less of the battery's power, since the process is mostly electrical in nature. However, when the processes you are using exhaust the physical memory resources available to your system, the system will turn to virtual memory to continue the process at hand. Virtual Memory is designed to extend system memory resources by building a memory swap file on the hard drive, and then transfer needed information between the hard drive and the physical memory as required. Since the hard drive is a electricity hog, the use of virtual memory becomes an electricity hog by proxy.

Two other processes that engage virtual memory on your computer are computational programs and the calculation processes used by spreadsheet applications and database programs. Both of these items engage the processor to a greater degree as well, which in itself is a consumer of electricity. Because they both compute and calculate large quantities of information, they will also increase the amount of electricity that your laptop will consume.
