Misunderstanding: After fully charged, persistent charging will get the laptop battery damage or even explode.
It is almost impossible for the battery to explode. At worst, the battery shell is melt caused by overheat while it is rare to be fire. In my opinion, it must be the accidents reported by media that makes the users to worry about it.
As a matter of fact, the causes of the accidents should attribute to the poor quality. Then it will cause a short circuit. Unless the accidents of the battery cells' cutting-out occur before the effect of protection circuit, they may be prevented by the circuit. For instance, the condition of the sony vaio laptop battery is as the former. Of course, it is really rare to all. Compared to mobile phones, it is odds small.
Nowadays, nearly all the batteries have temperature detecting circuits. Once the temperature comes to be high, it will be cut by the protection circuit to avoid the rise in temperature. Therefore, the probability to the exploration is similar with that to the lottery winnings.
Furthermore, the aging is unstoppable to the laptop battery. Even the best care products cannot prevent the beauty from being an old woman, which can only get it slow down. Therefore, the free warranty is no more than 1 full year while the other components should be longer.
If the laptop battery has been maintained properly, it can keep about 60% to 70% of the capacity in it after one year. In addition, you'd better remove the battery in use. Continuous serving rating is bound to make the battery worn down. On this occasion, it is better to get the laptop running with a stable external power supply.
Anyway, if possible, you can purchase a replacement compatible battery, such as ev089aa and ud260, of a high capacity. It will not only be used for a rainy day but extend the standby time as well. If there's no external power supply, the replacement will get you more fun with a double work time.
