How to save Laptop Battery
A battery has two essential characteristics, the voltage
expressed in volts (V) and the amount of electricity expressed in Ampere-hours
(Ah) or milliamp hours (mAh).
The battery power is calculated as follows: Voltage (V) x amount of electricity (Ah) = Energy (Wh)
Example: 19.5 V x 4400mAh = 85.8 Wh
Thus we speak of the capacity of energy instead of power.
What type of batteries used in laptops?
Currently, all batteries that come with laptops are made using Li-Ion technology. These are a type lithium battery in which lithium ion remains in state.
These batteries are expensive and that lithium is an expensive material. Its main advantage is the amount of energy we can store in a small volume.
Key Benefits
No memory effect or very low
Excellent amount of energy / volume due to the physical properties of lithium.
Self-discharge (natural discharge when the battery is not used) minimum.
Much safer in relation to the first lithium batteries (in the metallic state) through integrated electronic circuit.
The main drawbacks
The price, because of the complexity of manufacture and the material used (lithium)
Significant deterioration when the battery is discharged below 10% (can lose up to 20% capacity at once!).
Charging current limited because of its internal technology and the danger of lithium, so the load may seem slow.
Low temperature resistance: It is recommended to use at a temperature between 20 and 25 ° C, and must not exceed 40 ° C if it can be damaged. Never be achieved at elevated temperatures in the range of 75-80 ° C because they may explode.
Like all batteries they deteriorate over time and nothing can reverse this process.
ATTENTION:
The overall battery (batteries, lead acid batteries or lithium, etc.). Pollute the environment so it should never be thrown away. They should be recycled (in some countries will find in supermarkets and computer stores where you can leave them for recycling).
Never attempt to open a battery to repárala be burned or seriously intoxicated.
Increase the lifespan of the battery of a laptop
As stated above, changing battery is a real investment, the order of hundred euros usually is why it is better to know certain concepts and implement them to prolong their shelf life.
For example:
When you buy a battery the first thing to do (after seeing the power in W) is to see the date of manufacture: a battery loses its capacity from the moment it is made, therefore the more recent the datemanufacturing, the battery capacity will be very close to that listed on the label.
Prefer brands of batteries, especially not to buy discount batteries imported from China as they can be very dangerous because it probably had a very low quality control and even no quality control.So be careful as they can be dangerous!
Do not exceed the discharge current indicated by the battery manufacturer (eg: if listed 4400mAh then do not consume more than 4.4 A for one hour) and that can damage considerably. To be clear, it is advisable to use the battery to power other machines.
A very important point made earlier, never use it to below 10% load.In general the operating system puts the PC into standby when it is only 15% load. If you run the risk of losing 20% of its capacity at once, personally lost 10% of the capacity of my battery trying to prove ...
Do not use the battery while charging. But not to worry, because when we recharge the battery power cable power divided: some will charge the battery and the other is used to operate the laptop, so the battery is not used during this time.
Fully recharge the battery without interruption when it is downloaded to the maximum (not below 10% but when the operating system puts the laptop on standby). This allows the battery to do a full discharge followed by a full charge, which can keep it. This is recommended 1 to 2 times per month.
Another important point is that it is necessary to remove the battery when the PC is connected to the mains, and we do not need just because all current laptops (or the same batteries) are equipped with electronic circuits that prevent using the battery and is charged when the laptop is connected to the mains.
Instead, always disconnect the power cord from a laptop when off, to avoid any unnecessary burden on micro-battery.
It seems that Sony stops charging the battery to 80% of its new laptops to limit wear. So if you look at this on a Sony laptop there is no reason to worry.
