Away from the risk of explosion! Laptop battery use and maintenance

Back in 2006, the entire notebook industry is flooded with a keyword, is the battery. Prior to this, sporadic cell phone battery explosion, laptop battery explosion news appeared on the network and various media have been more or less, but 2006 Dell W953G Battery continuous number from the fire and explosion, no doubt these stars the fire, in one fell swoop fanned into a prairie fire.
After this, Sony gave nearly half of its annual profits to pay all these laptop batteries have exploded or unexploded. Dell WU946 Battery or increase a new understanding: "Dangerous Goods". Just beginning in the Year of the Pig soon ThinkPad and Sanyo joint recall laptop battery appears again in the spotlight, becoming the focus of media and consumer focus, leaving all laptop users use Sanyo batteries, fell into the new panic.

Why, then, the laptop battery explosion, we should be the proper use of laptop battery explosion and other accidents, how to avoid it? Let's take a look at the laptop battery by what.

This is a Dell Latitude D630 Battery, the structure can be said to be very simple control circuit coupled with a few pieces of lithium battery. These lithium batteries looks very much like we usually use AA batteries, of course, they are not actually inside the chemical composition and volume are not the same, the capacity is there is an order of magnitude gap. Although its appearance compared to traditional AA batteries has not a small gap, but in essence, it's still a lithium-ion (Li-ion) battery, let's look at lithium-ion (Li-ion) battery characteristics, as well as the use of to note.

Lithium-ion (Li-ion) batteries have a higher unit power and lighter weight, low popular before the memory effect than nickel-metal hydride (NiMH) batteries, so in the meantime, can be said is absolutely mainstream. Below 6 degrees Celsius, lithium-ion (Li-ion) battery will be a month of self-discharge, 5%, and the ideal way to preserve, is in the 40% charge after cold storage, you can save up to ten years.

For the life of lithium-ion (Li-ion) Dell Inspiron 1525 Battery, before there are a variety of claims, deep deep release sufficient, trickle charge and slow all people are familiar with, many users remove the battery save, not used as much as possible. But in fact, the lithium-ion (Li-ion) Battery life and number of charge cycles relationship is not very large, its life expectancy is 12-18 months. It should be noted, however, we can not make any deep discharge lithium-ion (Li-ion) battery, which is likely to make the battery completely scrapped. Similarly, 40% of the charge stored refrigerated for about three months, have to remove and re-charging, to avoid excessive self-discharge.

In addition, the lithium-ion (Li-ion) batteries are also very sensitive to temperature at high temperatures, which will significantly shorten the life, and may even explode; For low temperature of 0 degrees or below, its very likely to strike, and even completely end their own life. Thus for lithium-ion (Li-ion) battery, too high and too low temperature will bring no small problem, ranging from the impact of battery life, while is likely to cause an explosion, a direct threat to the lives and safety of the users.

How, then, whether the laptop battery maintenance and use it?

1 Avoid using the laptop battery in the high temperature case
As mentioned above, the Dell Inspiron 1520 Battery life in the case of high temperature will be severely shortened, there may even be a risk of explosion, so we should try to avoid laptop battery is used at high temperatures, as much as possible to improve the heat dissipation of the laptop environment can not only extend the laptop life, there are no small help for the laptop battery.
2 Try not to use the fast charge
In fact, now has a fast charging technology are international manufacturers. The birth of the technology for business people, and its role is obvious, those business people try to save valuable time. But, in fact, the fundamental principle of this technology is to increase the charging voltage and current, will bring more heat, and thereby rapidly reduce the battery life, and will significantly increase the risk of explosion of the battery. International manufacturers to design a lot of protection technology, but is not difficult to see from the last year from laptop battery explosion, these protection technology is not a panacea, fast charging still be able to avoid paying it.
3 minimize the battery charge and discharge
Constantly charging and discharging operations, will accelerate the damage to the battery, but the battery is removed another save, I do not advocate, after all, compared to the price of the laptop, the battery is completely negligible.
4 Do not use in damp or wet battery
In a damp or wet environment, it is prone to short-circuit, notebook battery damage is very large, ranging from damage to the battery and notebook, while direct occurrence of spontaneous combustion and explosions.
If the Dell xps m1730 battery overheating or inflation variability, stop using it immediately
In fact, has happened many laptop battery explosion, laptop battery million shipments per year, the probability of an explosion no less than on the street meteor hit, or said to be in the millions The lottery is much bigger, so we do not need too much fear for the battery to explode.
