It is often said that the first time we use a device equipped with a lithium battery (as I say, they are often called Li-ion) should be allowed to charge for eight or ten hours, but two or three hours (typical load one of these batteries) this device tell us that the battery is fully charged. This really was recommended when using Ni-MH batteries, but with the Li-ion is not absolutely necessary: a lithium battery always carries an overload protection circuit which is responsible for turning off the power once detects that the cells that make the battery has reached its standard level (usually from 4.2 volts).
Therefore, once the device says "full charge" does not enter more current to the battery and has no effect whatsoever on the leave her more time with the charger connected. Also they say that should do complete cycles of loading and unloading to avoid the "memory effect", that Ni-MH batteries was that if we put in charge a completely discharged was not missed part of the capacity of the battery from overcharging some of its cells.
In Li-ion batteries this is not necessary, and even more frequently as recommended and load cells are less time with current flowing through them. Li-ion batteries have no memory effect either and therefore we can load them better we come without having to wait until they are completely sold out as it did with the old batteries.
There are a number of things that are the worst thing that can make a lithium battery:
· The Heat: Li-ion battery loses capacity if stored in hot areas. Best suits them cold, but with keeping them below 25 degrees Celsius is more than acceptable. This is why batteries degrade some laptops very quickly if the design has not been taken into account that the area of the battery should be cold, ie, away from the hard drive and microprocessor.
· Store fully charged for a long time: it is best to keep a battery at half load, if we do so with the battery fully charged your battery cells suffer and will deteriorate over time. It should be stored fully discharged for a long time what we will see in the next point.
· Leave the battery to discharge completely, if a Li-ion battery becomes completely lost its charge will not load. This point is reached when the device is off because the battery has a very low level of energy, since that is responsible for the above-mentioned circuit protection. Over time the battery is losing charge itself (self-discharge rate) and if we can load many months to lower the minimum threshold needed to start charging and the battery unusable.
To extend the battery life:
* Reduce heat: The Li-Ion are highly susceptible to high temperatures, so use your devices in a cool environment will extend its functionality.
* Turn off wireless transmissions: Infrared (IrDA), Bluetooth and Wi-Fi are real vampires electricity, being equivalent to maintaining a cell at any given time. Turn off these features when necessary.
* Avoid using your CD or DVD: The spending not only borne by the laser, but also the motor that spins the disc. Better not to mention the writers?
* Reduce the brightness of the screen: Some teams do it automatically, generate less light, less energy demand.
* Remove memory cards or USB keys: Do not let its small size fool you, energize it requires an additional flow of electricity. This is especially true for small devices such as phones or PDAs.
* Avoid using audio applications: Even with headphones, the sound generation requires a constant expenditure of energy. Worse still if they feed external speakers.
