Do I need to remove the battery from your notebook to extend its service

About harm if the battery constant work from the power supply and whether permanently remove it from the laptop you need.

How does the laptop battery

There are two main types of battery - Li-Ion and Li-Polymer. Nickel-cadmium and nickel-metal hydride battery is not used today because they are not as reliable and effective. Li-Ion and Li-Polymer batteries run about the same, but have their advantages and disadvantages.

For example, a first higher power density, but they suffer from wear situated inside the liquid. The latter is generally more reliable, but less energy efficient.

The following two statements relate to two types:

1. The battery can not be charged excessively. If you leave the laptop plugged into a power outlet, then it will stop charging when it reaches the level of 100%.
2. Full discharge may cause permanent damage to the battery. This is due to the fact that lithium batteries, unlike nickel cadmium, have no charge profile.

As the battery generates energy

In lithium batteries, lithium ions are in the free state in the porous anode (negative electrode). When you turn on the power, the ions move through the electrolyte from the anode to the cathode (positive electrode).

As a result of this process, the battery is discharged. During charging, the ions move in the opposite direction, reversing the whole process. Since ions are again in the anode, ready to use.

Do I need to remove the battery

Modern batteries are much greater than their old counterparts. They are not subject to charge above the norm, they do not have the problems associated with charge profiles. Still, certain difficulties may arise with them.

During the hard work of a connected laptop power it produces more heat. Overheating - one of the main reasons for the reduction of battery life. Therefore, if you are going on for quite a long time to play or edit videos, the battery is better to remove.

Also, it makes sense to remove the battery if you are not going to use your laptop for a long time, such as a few weeks. In this case, experts recommend to charge up to 40% and disconnect the battery from the device. Since the chemical composition of the lithium cell will be complete.

Lithium-ion battery may age

Despite the fact that batteries are installed in almost every portable device, they are not perfect and are susceptible to breakage. Over time the ions become less effective in generating energy.

The battery has a limited service life. Ions are stuck and have not effectively move from the anode to the cathode, which reduces battery capacity. Lithium batteries begin to age immediately after the release, with the first charge. Causes of aging may include the following:

• High voltage. It is not necessary to keep the battery constantly charged. Constantly charged and discharged him, but do not allow a deep discharge.
• Heat. If it is above 21 ° C, then begin to occur in the accumulator chemical reactions, because of which it loses capacity.
• Low temperature. If it is equal to 0-5 ° C, the battery can be damaged and reduced capacity components. It is also likely to result in significant problems when attempting to charge the battery.
• Prolonged inactivity. Lithium-ion battery is being discharged by about 8% per month when stored it at 21 ° C. If the temperature is higher, the discharge rate increases. All this leads to a deep discharge.
• Physical blow. The battery can damage the banal fall to the ground.

Is it possible to extend battery life

Literally, you can not do that. But there is a set of rules under which the battery will work as long as possible and efficiently:

• Never bring the matter before deep discharge.
• Always partially discharge the battery and then charge it again.
• Avoid high temperatures.
• If possible, charged at a low voltage.
• Remove the battery when the laptop for a long time connected to the outlet.
• Charge and discharge the battery part - ideally from 20% to 80-85%.
• With prolonged inactivity charge the battery to 40% and periodically recharge it.
