Some Useful Knowledge For You When You Use A Li-ion Battery

The Li-ion batteries have a number of life cycles (cargo handling) that come to be about 500 to 1000.
500-1000 is assumed that after charging and discharging the battery is at 70% capacity, but this must be added the loss of capacity caused by the time the heat and the stored charge (the three points discussed above) . Nothing lasts forever, and the batteries do not escape this universal law. By the way, never remove intentéis one of these batteries, they are particularly unstable under certain conditions (that carry the famous circuit protection, circuit fails or is handled can even lead to the explosion of the battery as happened recently with some models laptop equipped with defective batteries).

It is true that the battery should take several cycles of charge / discharge before achieving peak performance?
No. This type of battery does not require a “break-in period.” Enjoy all your load capacity from the start.

I have a PDA or mobile phone, does it just load the transformer using the USB cable?
DEPENDS. Some computers are not able to maintain the necessary amperage to charge your battery, so it might take much longer. The charger will always give you the right to charge the device, optimizing the load time.

Is it harmful for a laptop battery that always work plugged in?
Yes, in fact, is not only harmful, but it is a very detrimental to the battery due to heat and stress it is subjected. The heat generated when connected permanently diminishes the capacity of the battery to retain power. In fact, a lithium-ion battery should never exceed 60 °, which is pretty close to 40 ° or 50 ° to a working laptop. When you plugged the computer, you’re forcing your Mantana battery always 100% load. The constant stress that is submitted is also crucial. If for example a battery to keep 100% at 60 °, after 3 months only retain 60% of its original capacity, and its useful life will be reduced to only 12 months.

I will not use my device for a few months or plan to use at a fixed site, how do I store the battery?
A lithium-ion battery holds better over time with a 40% charge. If we keep one with 40% charge after a year will keep 96% of its capacity, while if the store 100% charged, retained only 80%. For this reason, most devices come with a small initial charge, the 40%. Of course, never store a lithium battery discharged. Irecuperable could cause damage.

Batteries may explode
Half-truth: Of all the battery types listed above, the lithium ion batteries are more prone to overheat and explode, because they are made of flammable materials. For this reason these batteries incorporate several electronic circuits that control protection at all times the status of the battery. As a general rule, you should store at a temperature of about 15º.

The lithium ion batteries are the best
Depends on the conditions of the device on to be incorporated. It is true that Lithium ion batteries are the most popular due to its light weight, high capacity (up to three times the voltage per cell than a single Ni-Cd or Ni-MH) and almost no memory effect, but life is less than that of Ni-Cd or Ni-MH, worse working in extreme conditions like extreme cold, and tend to overheat. Thus, the choice of one or other type of battery depends on the size, weight and working environment of the electronic device in question.
