Expensive original battery, compatible battery laptop battery is dangerous, Xiaobian have thought of replacing batteries of the "extreme way", because the level of Sally's own computers are not high, so Xiaobian pre-empt, straight to the business of maintenance notebook.

Investment in the country and in the sea of electronic markets, engaging in business transactions, both second-hand laptop, told reporters that can provide this is what they call "changing core" of the maintenance service. A press conference in the hands of IBM 600E original equipment batteries, for example, "for the core" costs about 100-300 yuan, the process is very simple, just have a basic welding equipment and technology can be completed. In the repair site, the reporter saw repair personnel forced open the original battery, will the old batteries (similar to a common rechargeable batteries) Toshiba Tecra 8000 Battery out, and then the new batteries in accordance with AS followed by spot-welding connection shall succeed, as a whole did not use more than 30 minutes. "In fact, the majority of laptop batteries are not rechargeable batteries as a result of aging, as long as the battery charge-discharge control circuit board not bad, this maintenance of nearly 100% success rate." The businessmen explained that,

The business also revealed that the current batteries in circulation are from the South to buy large quantities. Electronic market in the South, "for the core" no longer a secret, but until early this year, a large number of the electronics market in Beijing, but also very popular. "In the 'blue fast', where the block to buy a new battery Toshiba Satellite A75 Battery at least 1,000 yuan more than the price that many customers are cheaper to come to this for Ben Zhao."

Reporter interviewed a number of IBM products is responsible for after-sales service "Blue Express" the staff, for this "change the core" behavior they both said that did not know, nor did conduct a customer complaint. However, a staff member confirmed that the purchase of a new 600E battery needs to spend about 2,400 yuan.

For the difference between the price disparity, "Blue Express" Department of Propaganda and Miss Yu said, IBM has its own global pricing strategy, the company did not modify the permissions, but whether they would opt to repair the battery Toshiba Satellite A70 Battery is the client's freedom. At the same time because of environmental considerations, IBM customers will be turned over to the scrap batteries, commissioned by professional companies to focus on the destruction, the process takes a lot of money.

With a simple repair process, capacity to make mischief laptop battery to work again to spend the cost of buying a new battery is only one-eighth. Professionals to remind consumers that this kind of "change core" cell there is a certain security risk.

"Blue Express" the technical staff, told reporters without permission "for the core," there is a big security risk, some rechargeable batteries without the detection of Toshiba Satellite A100 Battery short-circuit even after the burst phenomenon, ranging from damage to the host, while in the explosion .

In addition to insecurity, the provision of core services for businesses and maintenance of the level of quality varies, Xiaobian businesses in and a chat we know that some black-hearted battery maintenance providers, in order to earn huge profits, the quality of the best times to take the battery to serve as a good battery, and the worse the battery inside the control chip removed, only one wire connected to, or have already been scrapped on the circuit board inside the battery charge a few. Said that a serious point, so that the battery can not think of the problem is immune.

As shown below, these three 600E batteries are looking from another core, but only one in the formal business that repairs off, and the remaining two belong to the products in question, let's see how.

We can see that three batteries Toshiba Satellite A10 Battery opened, there is a control circuit do not even have to know the control circuit is the heart of laptop batteries, no matter how good the control circuit even if the battery can not be a computer to identify, because the books to pass this piece of the circuit board access to the battery information, know whether the battery is full, state how much the temperature, if the get an error message, such as: battery temperature is already too high at this time the books are still kept a strong charge to the battery input current, the consequences People can imagine.

Let us now take a look at the left of that piece of batteries, at first glance seems up control circuit is not small, but you look carefully that there are a fly line across the circuit board, it is also more than just that angry, or else you'll do anything put, take a useless thing every one, maybe you said that change of a good board, you do not know how it was.
This three batteries, only the far right of the piece is authentic, we can see that clearly marked chips, circuit board and clean elements arranged in order.
To the core books for the practice of the battery is really a last resort, if you take that risk, then the non-, or select some have a certain scale, with professional Toshiba Portege 4000 Battery equipment businesses, but also in the replacement process, not from the people, should be observed from start to finish carefully, so that maintenance personnel face to face for the core, otherwise there could be two questions above the battery.

After the battery change are not happy too early, you'd better bring books to go with the spot test and see a good core for how long the battery can be used in general to reach a half-hour or more, then the core of this change Now that's a successful operation, it is especially important at the beginning of change must be before and merchants said yes.

End-cell battery for perhaps you will find that the battery Toshiba PA3591U-1BRS Battery can not be filled with the phenomenon of merchants to Xiaobian said, if you encounter such a situation, as long as several times a full charge and discharge times can be solved, principles similar to the calibration of the battery program. We should know that the battery is intelligent books, in addition to the battery body hardware, there are software, computer exists in the battery through the circuit board of the information that the state of the battery, just for a good cell battery and the original control due to the circuit the battery documented information exists error, the need for a period of transition.

Change batteries, even though the price is very low, normal 2200mAh capacity batteries as long as the 20,30 yuan, the whole simply discarded not exceeding 300, but the one hand, the quality of batteries is not easy to control, on the other hand there are certain risks operation If there is no super-manipulative ability, do not plunge. In short, change of the "core" you still think Toshiba PA3506U-1BRS Battery twice for the Miao
