In recent years, due to explosion of mobile phone battery resulting in deaths and injuries and current newspapers, many of them “Motorola”, “Nokia” and the presence of other global brands. Previously, a cellular phone explosion Changhong news to turn public attention on the body of the handset Sony VGP-BPS8 Sony VGP-BPS8A battery.

The status quo of mobile phone battery in China

As mobile phones become more powerful, the requirements of the capacity utilization of the battery are increasingly high. In recent years, the industry began widespread use of Bigger, Longer lithium-ion batteries. But until now, state authorities have not promulgated lithium-ion batteries for national testing standards.

It is reported that Chinese demand for mobile phones and batteries were more than 300 million euros, the sub-market battery is compatible with original batteries and battery of two. With original batteries are most often on their own manufacturing, quality is relatively good, but the high price. Currently the market is compatible with a growing percentage of the battery, compatible battery prices generally higher than the same size of the original battery is low but the quality is mixed.

The industry calls the new standard

“Around 2000, the capacity of mobile phone battery is very low, low energy density, 150 ℃ temperature normal, there is no problem. However, with the constant development of multi-function mobile phones and user demand for the startup time, the ability of mobile phone battery larger and larger, high-capacity battery can not withstand 150 ℃ standards, in particular, more than 1000 milliamps of battery capacity can be 130 ℃ test, then what is the use of 150 ℃ or 130 ℃ that standards of heat shock temperature has been controversial for many years. “The person explains:” Until now, the authorities’ state has not promulgated lithium-ion batteries for national testing standards.

In 2003, the Ministry of Information Industry promulgated YD1268-2003 “mobile phones and lithium batteries and charger safety requirements and test methods”, in which temperature standard impact test heat have been changed to 130 ℃, become the mobile phone industry, to test the general industry standards, in September 2005 by the State Administration of Quality Supervision, Inspection and Quarantine and the ‘National Standardization Technical Committee alkaline batteries under the auspices of the national meeting standard review, the new proposed national standard, “revised edition”, in which the temperature standards for thermal shock test in A 130 ℃, but for various reasons, is expected in September 2005 enacted a new national standard has not yet issued. Currently, both the manufacturer of the battery or the mobile phone manufacturers in general would be 130 ℃ as a temperature the lithium-ion battery testing standards for thermal shock, and the battery design, production, quality control, procurement and other areas commonly used by this standard.

According to industry experts, the State is currently testing the use of thermal shock test is to put the battery in the box with hot (5 ℃ ± 2 ℃) / min rate up to 150 ℃ ± 2 ℃ and heat for 30 minutes, the battery does not catch fire or leak, which is a simulation of destructive tests in extreme conditions. In fact, consumers may find difficult to meet in the use of mobile phones such as the use of the environment, even the 130 ℃, was also well beyond the daily use of mobile phones for consumers when the temperature limit. Substituting Nokia, Motorola, Amoi, Lenovo Mobile brand to represent the mainstream of the original battery, all with very catchy captions to remind consumers not to the battery in fire or heat to avoid explosion.

Development of the industry trend, the mobile phone battery need a new standard. Now, only a small number of Nokia and other mobile phone companies use a unified standard battery. At present, China has gradually become the world’s lithium-ion battery manufacturing facility. Release of the lithium-ion batteries in 2005 to about 35% of the world, with exports amounting to 2.32 billion dollars, has become the second largest production of lithium-ion batteries and the exporting country.

It was also revealed that currently outside temperature standards for thermal shock test, the 2000 version of mobile phone batteries in the specification old national standard for several other standards are multiple industry, partisan wrangling. After 7 years, when the new version of national testing standards at the end, when he introduced, drew the attention of the industry. Inspiron 5100 battery Inspiron 5150 battery

In batteries for IBM laptop use, the activation operation for various reasons, often in detail the operation error unwittingly inadvertently harm your sony Sony VGP-BPS2B Sony VGP-BPS2C battery.

Here we cite two examples to the detailed analysis to explain the “operational details” of importance.

Example 1: When the laptop on ac power to the state, stop it, when to unplug the AC plug? Work completed after a short period of the screen, this time, it is easy to think that success has been closed and unplug the mains plug immediately easily, they do not know the screen while closed, but the power indicator light on mother (circle with a Z-shaped like light) is always light, laptop computer, in fact, still working at that time, which means that the computer time needed to supply electricity If when you unplug the AC plug, AC power from the laptop will be immediately converted into piles Status status, the unjustified use of a second bit, the battery, so even if the number seems not to take power but accelerate the battery more quickly fell to all initial charge capacity, which reduces the battery charge with the cycle, affecting the battery life. No exchange of pulling the plug early, pull night will do? When the motherboard power on the LED turns off (the power light is lit), if not unplug the AC plug, procedures for system power management and battery inside the battery microcomputer interface management composed of approximately 5 seconds, will be automatically transferred to the “off-load condition, so the delay after the cessation does not disconnect the power plug will be no reason for” 96% of cells a short time, load, while the damage your battery. [The battery is not fully discharged before (eg electricity at 5 ~ 100%), to recharge the battery, otherwise it will shorten the lifespan of the battery. Vostro 1500 battery Vostro 1700 battery

Global above, the best methods of operation are: In addition to light the power light off the bottom of the screen all the indicator light turns off, unplug the AC plug that, with (at later 5 seconds), socket pulled out about 5 seconds after the power light turns off automatically.

According to the above analysis we can see, the original AC power, the intention is to minimize the use of the battery, thereby extending the battery with the cycle, while in the operation due to deficiencies in the details’, Ai Qing Qing anti unfinished “harm;” operational details “The importance is obvious.

Example 2: When using the AC power supply, AC adapter AC input and DC output plug plug device (unload) the operational details of the sequence is a connoisseur. Good operating practices are as follows: First the power adapter DC output plug the power jack on the laptop, then plug it into 220V AC input AC outlet and must be removed when you First disconnect the AC input jack, and remove the DC output plug. If the record (no load), the reversed sequence AC adapter is provided at no charge, power adapter is not permitted in any load condition, and because of their work on the state of the pulse, no switch load in the transformer windings will produce very high peak pressure ventilation, such as anti-IC, capacitors, voltage sensitive components. Although the AC adapter has been created in which no-circuit load protection, but because of the design must take into account other issues, the protective effect of this protection circuit is very limited, therefore, when the AC adapter at no charge state from time to time may be damaged.

From the above analysis we can understand that in operation are so important in retail, and does not vague and impersonal, “said the great thing is that we generally speak of the conservative nature of science and technology. To this end, I feel the need to write some of my old rules for the operation on the battery to make the appropriate changes to the text, sorting, for reference, to draw attention to the details of operation, but also please the teacher criticized corrections and additions. Part of the increase due to the limitation, the following is impossible, as another example, in the example above, a detailed analysis, this item please forgive me too.

Active Treatment:

The following conditions are necessary to enable the treatment of piles:

1. Just open a new battery.

2. For a long time, do not use the battery, the battery away from your computer to the inventory situation is now reactivate the battery.

3. A long time do not use the battery from the notebook or laptop stand out of storage (more than two or three months) and are now reactivate the battery.

To enable methods of treatment of battery:

Activate the battery chemicals, to maximize PA3399U-2BRS PA3465U-1BRS battery performance through repeated charge and discharge the battery (fully charged and then fully discharge) three times. The so-called fully responsible and defense case: the normal startup so that the battery consumption to 3% of battery power (preferably once exhausted, can be divided into several times in power, but not interval too long), then must immediately close the battery noon.

Here, stressed the need for an immediate battery because the battery will be achieved without the use of self-discharge when the battery to 3% of electricity at that time if the charging time of battery, phenomenon of self-discharge the battery can easily result in an excessive discharge the battery on the lithium battery discharge is a big taboo.

Activation by the battery, the machine must be disabled. If the machine this time of waiting, waiting for these states, when the load to 3 ~ 4 hours after the Green Power status LED indicator has stopped beating, the machine automatically stops charging the battery for the battery can not be fully charged. When discharge to 3% of electricity, the device will automatically switch into sleep mode right now, this period should be restarted the machine, the machine starts the process, click Stop button in the lower left of the screen so that the machine stopped.

If this operation had a good understanding of each and every detail, and quality of your battery has no problem, we may very well turn the battery chemicals, to optimize the performance of the battery is basically a normal battery after each use to be able to reach 100%.
