Most of laptop user leave the battery in laptop since they get begin to use laptop. They do not care the charge-discharge not to mention the battery life which is count by charge cycle.
You need to charge battery to 100% or drain it to shutdown automatically during the process of using laptop. It is says, charging the battery to 20% and keeping it on 98% are the best way.
If you find out your battery can not be charged fully but the charging has been stopped, the battery indicator maybe need to calibrate. Calibrating battery in time will help you to active the battery and might recover a part of loss capacity.
If your laptop is bought many years ago, you must to charge it fully every time in order to maintain battery capacity because of memory effect. But it is unnecessary to charge you new battery which is got in the last few years.
In fact the lithium batteries have a little memory effect. The lithium battery material is very sensitive to the environmental conditions such as temperature, the frequency of using and so on. The battery will be aging after some period time (standby time reduced). The natural wear and tear is the important factor and inadequate maintenance is another one.
Now, do you think the battery is too damageable to maintain? Do not worry. The well-designed lithium batteries have a very good protection circuit to prevent overcharge and over discharge. The over-charging and discharging of the battery will reduce the battery life rapidly. But you just charge your battery without controlling the charge because of the battery protection circuit will stop charging automatically when it is charged fully. In fact, it is hard to achieve to “Full”, just ignore it.
As a laptop user, I think you might have find out that thought the Windows System show that the battery capacity still has 15% or more and you can use it for 25 minutes, But the laptop shut down suddenly before in 20 minutes. The factor is the battery has been aged. The battery indicator can not show the battery real capacity. After depletion for one year or more, the protection circuit original parameters can not reflect the actual capacity of the battery.
So some software that offer calibration come on! Though we can calibrate it by ourselves, it is too complex to most of laptop common user. You can use the software to help you to correct the battery circuit parameters by following the wizard of the calibration which is offered by the software. By the way, the calibration process will lasts more than three hours. You must consider it clearly before you do it.
I’m an officer of espow company which is design, make, and sell laptop battery by http://www.laptop-battery-charger.net. I have an interest in laptop especially laptop battery. So I have lots of experience about battery.

Mobile Phone Batteries. What Are Your Options?
by: Will Koh
There are a range of different mobile phone, video camera/camcorder and digital camera batteries out there with varying capacities and battery chemistry. We will explain what the differences are for each battery chemistry and try to clear up the jargon used on the labels of mobile phone batteries. There have been several developments in battery technology and below, we will outline each battery chemistry’s features, pros and cons and their applications to mobile phones today.
“Memory Effect” in Batteries
Memory affect refers to the need for certain batteries to be “serviced” by regularly discharging the battery completely before recharging. Ni-Cad batteries are the main type of battery chemistry that requires this cycling and newer types of batteries such as Li-Ion and NiMH do not suffer from memory affect.
Battery Capacity Ratings
A battery capacity rating refers to the load or current that can be placed on a specific battery type. The battery capacity rating is usually measured in milliampres (mAH)
Ni-Cad (Nickel Cadmium) Batteries
In the past, majority of rechargable batteries used in portable devices such as mobile phones, camcorders and cordless phones used Nickel Cadmium as the main battery chemistry. Although this type of battery has drawbacks such as the “memory effect”, it is still one of the most commonly used battery in cordless phones, CD players, Radios and other portable devices due to their low cost per battery cycle. The use of these batteries in mobile phones today is rare due to their memory effect problems and inconveniences. Despite these obvious drawbacks, it also has environmental implications due to the metal used to manufacture these batteries and are fast becoming replaced by Nickel Metal Hydride Batteries.
NiMH (Nickel Metal Hydride) Batteries
NiMH batteries are one of the growing battery chemistries today mainly due to the fact that it does not suffer from memory effects like a NiCad battery does. Because of this advantage, they are mainly used in Laptops and mobile phones and sometimes also as a battery source for video cameras and digital cameras. This is an important and main feature that makes NiMH batteries attractive as consumers are not burdened by having to “service” their batteries by discharging it fully before recharging. They also have a higher capacity rating compared to Ni-Cad (approx 30% higher) and Alkaline batteries, however their main drawback is that these batteries self-discharge over a short period of time which makes them not suitable for storage.
Li-Ion (Lithium-Ion) Batteries
These batteries are quite new to the market and have the lowest discharge rating compared to Ni-Cad and NiMH batteries. They do not suffer from memory effect and is one of the most commonly used type of batteries in mobile phones today. They have an excellent power to weight ratio which makes them highly attractive to portable devices such as mobile phones, video cameras and digital cameras. All our mobile phone batteries we offer are Li-Ion as they are superior compared to other battery alternatives.
Li-Polymer
This is relatively new and we are beginning to see more of these batteries appear in mobile phones today. They are considered as the best battery chemistry today for mobile devices due to their high capacity and low weight. Li-Polymer batteries do not suffer from “memory loss”.
