Cellular structure, even if a simple, but really qualified to make a battery is not so simple. A product must first select the batteries, the batteries are often poor internal resistance, voltage, charge and discharge targets difficult to meet demand, to do outside of the product is mixed. Currently several regular-purpose manufacturers Sanyo, Samsung, Toshiba, LG, Bak and other brands of batteries. After storage piles should be tested for their targets and indicators in the 2% difference in the batteries can be combined in series or parallel circuit composed of, if not a target of batteries and other batteries because of very different in the IBM ThinkPad R51 battery charge-discharge process will be expressed in the form of charging or discharging the battery have not yet succeeded, and that person was on battery charge or discharge, resulting in the battery does not work The difference in the long term, larger batteries, or over-charging after discharge, leakage or even an explosion that may arise. Manufacturers of battery test and matching precision instruments and equipment, the computer generally rely on the city known as the professional maintenance staff will be able to complete the multimeter, and they rely on a multimeter can be achieved at best is to check the battery internal resistance within the accuracy required, as actual battery storage, life, load and discharge the effective time, no equipment professional may not detect a real sense can not be matched, said maintenance is also a form, the storage battery maintenance has not increased is not.

Laptop battery life is typically 300 times the total charge and discharge, and half a year or two to replace a new battery, laptop batteries home are not cheap, easy miles, a few friends to spend no so much money to buy laptop Dell Latitude D800 battery replacement while the thought of batteries, which should not be? This security risk it?

At this point, I visited the electronics market, engage in commercial transactions, both second-hand phones, “said the writer who can provide what they call” change of base” maintenance department. In the author in the hands of IBM 600E batteries original equipment, for example, “to the” core costs about 100-300 yuan, and its process is very simple, you come from a welding equipment and technology base can be completed. In keeping laptop battery site, the reporter saw the repair personnel forced the original battery, will the old batteries out, then it is in compliance with the new batteries in place in turn connected to future and the whole process should not exceed 30 minutes. “In fact, most laptop batteries are not rechargeable batteries as a result of aging, as the battery and the control board’s discharge circuit is not evil, this servicing almost 100% Success. “Merchant said:

Maintenance Activity has also revealed that the batteries are currently in circulation in developing countries to purchase large quantities. Repairs inside the hp Pavilion dv4 battery until earlier this year, appeared in large numbers on the local market for electronics, but also very popular. “In the ‘Fast blue’, where the block to buy a new battery at least 1,000 yuan more than the price that many customers are less expensive to come to this for Ben Zhao. ”

I interviewed a number of IBM products is responsible for after-sales service “Blue Express” staff to “change the basic behavior that they have both said that did not know, has not proceed with a complaint from a customer. However, a staff member confirmed that the purchase of a new 600E battery needs to spend about 2,400 yuan, one can say is equivalent to half the price of a mobile home.

For the difference between the price gap, “Blue Express” the head of the Propaganda Department, said, IBM has its own pricing strategy worldwide, the company does not change the permissions, but if you opt to repair the Battery is the freedom of the client. At the same time due to environmental considerations, IBM customers will be given to scrap batteries, commanded by professional companies to focus on destruction, the process takes a lot of money.

Given the “cheap appeasement” of the laptop battery for the central process, professionals advise that the essence of “change” cell there is a security risk.

“Blue Express” the technical staff, told Reporters Without authorization “for the core,” there is a big security risk, some rechargeable batteries without detection of short-circuit even after the bursting phenomenon, ranging from damage to host, while in the explosion, and even life threatening for the user. It’s really unwise to be too expensive, not as good as the batteries of laptop OEM buy. In Indeed, many claimed to be original battery is OEM like Dell’s brother, there are parts that are not OEM? Batteries for laptops OEM manufacturers of batteries are imported actual performance and few differences of origin because it is produced locally (mainly in the south, some manufacturers), low cost and no import tax to pay so much, so only one third the price of imports or less. In addition to the sony VGP-BPS5 battery purposes of basic insecurity, the provision of basic services for businesses and maintaining the level of uneven quality, inside and chat in a company, some Black Hearted providers battery maintenance to earn huge profits, taking the quality of the best moments cells act as a good battery, and worse, the battery inside the controller chip removed, but only one wire connected to, or have already been demolished on the circuit inside the battery some. Tell a serious argument, so that the battery can not think are all very hard.

An uninterruptible power supply (UPS), batteries can be considered the backbone of this system, there is no UPS batteries can not be called a stabilization of the voltage regulator frequency (CVCF) outlet. While UPS inverter can be reached, because of the battery, electrical anomalies in the city when the drive directly the chemical energy of the Laptop battery electric power, transportation outside the exchange, use the continuous operation of equipment Power to continue.

At present, widely used in small and medium UPS Power Supply Maintenance-free sealed lead-acid batteries, which accounts for the power of UPS’s total cost 1/4-1/2 as much, not only that The repair itself also shows that nearly 50% or more of the power outage in connection with UPS battery UPS. UPS battery failure occurs mainly enough voltage, capacity, inadequate or transient discharge current is configured to boot does not meet requirements.

The normal use of the UPS, the battery life of 5 years or more, but a considerable part of the internal IBM ThinkPad T42 battery of the UPS is placed in service for less than a year started having problems worse, some imported brands and the manufacturing process of household batteries there are birth defects, the other is due to lack of maintenance necessary to cause acquired. It is worth noting that many use unit tests due to lack of maintenance actions required are not clear about their health system, for systems UPS battery UPS to work to stay hidden .

Use one to five years batteries, do not use it? Spent half a year if the battery can certainly be used? UPS battery is provided by the supplier must be good? — The necessary testing tools.

“A mouse, a pot of soup bad, drums festival dozen rounds, until a premature damage, not detected in time, then over time, other cells followed discarded. – Screening early.

Many UPS failure, the first is expensive to put the battery because the battery voltage due to various reasons, firstly reduced while maintaining the appropriate detection means, people did not. Spending tens of thousands of establishing back-up power system, due to the Dell Latitude D800 battery state of uncertainty, where the system failures, it is important to data loss, the consequences are unthinkable and its huge loss, with tens of thousands of people, far from being able to make money.

The state had known!

UPS battery test and maintenance of traditional methods of

UPS General Power requirements of the battery: in response to a voltage across some, the battery should be able to start the moment the output of high-current discharge characteristics, to meet a certain capacity to ensure Power Supply Inverter time.

1, with the multimeter measures the battery terminal voltage

Practice has proved that with a multimeter measuring UPS battery float voltage is unable to determine if the old battery is no longer valid. Thus, generally off-line or on-line measurement of the voltage across the hp F4486B battery, the battery terminal voltage measured is about 12V (12V for the battery case) and the minimum may not be less than 10.5V. Must be less than 10.5 V battery voltage, battery or has expired. If the battery charge after charge or activate the back-end voltage still can not reach 12V, the battery must be valid.

2, to test whether the UPS batteries to start an Instant high-current characteristics of output

UPS Off-line power by the municipal power supply power inverter switching time requirements of less than 7 ms, generally designed to be about 4-5ms. This means that, once the interruption of electricity supply, UPS batteries must be less than the 4-5 ms time required for the output load current. Failure to respond to some of the voltage across the battery capacity needs, but not less than 4-5ms-current in the discharge current to meet the requirement for substandard batteries. UPS Batteries major characteristics of the instantaneous current production in the closure of the power to test sony VGP-BPS2A battery performance without knowing the circumstances, there is a certain degree of risk, is generally not performed.

3, determine the battery capacity of the UPS

UPS battery capacity of traditional discriminant and determine the same manner as ordinary batteries, the entire group of system battery power supply and resistance of wire communications, eight or 10 hours rate constant current discharge, and then the first to reach the end voltage discharge of a particular time of battery discharge current monomer and to project their capacity.

The ability of traditional test offers the following advantages:

⑴ take the battery system, increasing the risk of system crashes;

⑵ discharge time, and the need to manually test cases, heavy workload, in addition to the UPS batteries are typically installed on the box-office type, the test is not easy;

⑶ wire resistance and is red-hot phenomenon of intensity bulky, dangerous work.

Maintaining the status quo of the internal battery UPS

UPS battery care and general maintenance of the low pressure system similar to the toshiba PA3465U-1BRS battery, when the introduction of new batteries, to require acceptance of the internal resistance of the battery voltage, test simultaneously ensure that their resistance internal consistency, and when the new battery into service, requires the maintenance of working environment suited to the battery temperature, require regular measurement of the voltage across the battery internal resistance, when the battery internal resistance or pressure is too great, it is necessary to have sufficient and regular deep cycle battery to verify battery performance priority poverty and the maintenance of cellular activity.

But the practical application, due to various conditions, limitations, UPS battery in full conformity with the maintenance of very few people mentioned above, the tools of first acceptance of a new battery, because of long time nor convenient to use, a considerable number of people do not This work will build on the battery in use, according to statistics, mainland China, approximately 95% of the UPS batteries lack of necessary maintenance UPS power supply for the future that the fault was concealed; Secondly, the new battery into service, because of the UPS battery is generally installed in the cabinet, the measurement is not out of convenience, low internal resistance and voltage measurement in accordance with existing conditions (98% or more of the UPS battery is not installed surveillance equipment), the majority of maintenance personnel can perform that at intervals of time, cut electricity to UPS batteries on the actual length of time of discharge system, at best, do click on the battery pack activation to maintain cell activity, and the battery performance and the advantages and disadvantages of remaining battery capacity and other important data, or no way of knowing.
