Cells Lithium Ion battery can be drained or explode if heated to temperatures above 60 degrees, or if they are loaded beyond their power limit. Another problem is that the cells are rapidly oxidized when they are fully discharged, which demands close attention if the battery is completely depleted. To make reliable batteries, all Li-Ion batteries used commercially have some sort of intelligent circuit that monitors the battery charge. This stops charging when the battery voltage reaches a limit and stops the supply when the battery is discharged, in order to avoid discharge.
Another interesting question, especially notebooks, is that the batteries are composed of 3-9 independent cells. The circuit is monitoring the voltage of individual cell, but only the set. This means that in situations where the cells are out of balance, or in cases where a cell is defective premature, the circuit interrupts the power supply after a short time of use. Then come the many cases where a battery that originally lasted 2 hours, 15 minutes passes last, for example.
In most notebooks, the battery circuit works in conjunction with the BIOS of the motherboard, which creates a possibility of various errors. Commonly, after several partial loads, the monitor is out of balance BIOS and go to calculate the capacity of the battery the wrong way. Then whenever you are making partial refills, which will make the battery last less and less, although the cells remain perfectly healthy.
This is why so many notebooks include utilities to "calibrate" the battery, available in the setup. This tool performs a charge and discharge cycle complete, updated measurements. When you leave it unused, Li-ion batteries deteriorate faster when fully loaded or unloaded, therefore, it is best to leave the battery with a 40% load. Heat also speeds up the process, therefore, the colder the environment, the better. A fully charged battery, stored in an oven at 60 C, you may lose more than 40% of its capacity after only 3 months, while a battery retains the 0 C, with 40% load, will lose only 2% after one year.
Avoid discharging the battery when not needed. The best thing is simply to use and charge battery according to its cycle of use. Another tip is that the battery life is less when subjected to fast downloads, so burn DVDs with the notebook using the battery power is not a good idea. Every 20 or 30 cartridges, it is interesting to make a complete cycle of loading and unloading, in order to "calibrate" the measurements of the chip and the BIOS monitor.
At first, removing the battery from a laptop that is connected to making the most of the time would be a good idea to increase its life. The problem is that most notebooks use battery and surge protection from the mains. Removing the battery, this protection is lost, which can shorten equipment life.
