    Toshiba recently announced the introduction of number of maximum capacity for 32 GB of embedded NAND flash memory modules, and announced that these products in full compliance with e-MMC and eSD standards. These embedded products for the mobile digital consumer products, including mobile phones and digital cameras. Samples will be shipped in September 2008, from the fourth quarter of volume production.

1. Under normal circumstances, the new nickel-hydrogen laptop battery contains only a small amount of electricity, we must first purchase and then charge for use. However, if the battery factory relatively short time, electricity is enough, and then use the recommended charge.

2. Buy the new nickel-metal hydride batteries in general to go through 3-4 on the charge and use of performance can play to the best condition, many friends in the first charge of the minor problems encountered, for example, the first charge after the film did not imagine the number of PP So many ah » 3-4, in charge after all resolved and the use of the.

3. Although the nickel-metal hydride batteries on the memory effect, we still recommend the use of End as far as possible after each charge, and is full of one-time, do not charge for a one-and then will charge. This is the “longevity” Oh that’s important.

4. Batteries, chargers to the attention of the surrounding heat, too deliberately blowing what fans have no need, but to the attention of the charger is not to put too much around the debris. Ordinary users in the use of batteries in the process of batteries are often not dedicated storage bags; users to replace batteries, will be used in the batteries readily placed, regardless of whether the release of clean, damp. The consequences of such cells is easily soiled and easy contact with the metal   such as keys, and other contacts, easily exposed to moisture, and these are the great enemy of the ibm battery. Recommendations: the user should set up a special cell at points, and maintain the battery clean. In order to avoid the loss of electricity and other problems, and maintain the battery ends of the contact point and the internal battery lid clean and, if necessary, use soft, clean dry cloth Qingca.

5.’s Not a long time, remember that the battery removed from the battery positions, dry place in an environment recommended Add to licensing the battery box, avoid short-circuit.

6. Do not have the long-term nickel-hydrogen batteries will be stored in a few months later, the battery and entered a “dormant” status, ThinkPad T30 battery  life greatly reduced. If the nickel-metal hydride batteries have been placed for a very long time, I suggest you to use the slow filling suitable for charging. Here involves another key issue: the nickel-hydrogen batteries, the battery should be fully discharged after save, save or charged » These two very different viewpoints, which should be used? » Many people think that we should use the former, but I think that kept the battery charged more reasonable. Because: It has been tested, nickel-hydrogen battery is kept charged in the best conditions for about 80 percent of preservation. This is because the nickel-hydrogen battery self-discharge more (10% -15% a month or so), if the battery is fully preserved after discharge, for a long time not to use, the battery self-discharge phenomenon will result in a battery discharge, Will damage the battery. Do not believe » Then you think about buying a new nickel-metal hydride rechargeable batteries, there is not all, of which this is the truth. Recommendations: more, correct its wrong view, the right direction from the start with maintenance of batteries, otherwise they will be counterproductive.

7. Have a lot of friends post asked how to discharge the nickel-metal hydride » In many asked about the ThinkPad X60 battery  of experts, the conclusions reached an agreement to remind friends. Do not try to nickel-hydrogen batteries discharge, the release will lead to charging failure to do so against nickel-hydrogen batteries are far greater than their own memory effect!

8. Multimeter is a self-test battery. General in charge nickel-metal hydride batteries, voltage 1.2 V below the normal voltage in full after around 1.4 V. All this judgement, it is very easy to judge the status of the battery.

9. Chargers are divided into fast and slow filling charge. Slow flow of small charge, usually around 200 mA, such as our common charge current is about 160 mA. She’s charging a long time, the 1800 mAh rechargeable nickel-hydrogen batteries to about 16 hours. Although time is a little slow, but the charge will be sufficient enough to injury and not batteries. Usually fast-charging in more than 400 mA, charging significantly reduce the time many ,3-four hours you can get, also won everyone’s favorite. There are many kinds of fast filling, different prices. Therefore, we often have doubt, is fast filling the same, why the price difference is great » Particularly good charger is good with a fast-filling are charging excessive protection, for example, our common Matsushita Need charger BQ 390 in this regard is particularly good, excellent chip design capabilities in software for battery charging, Also quick to charge the battery down to a minimum of harm.

10. Contradictions arise: slow PCGA-BP2EA  charge is not injured but charging time is too long; fast filling can save time, but the batteries have hurt, even if the world is the best surface Matsushita Need charger BQ390 can only be good to reduce the extent of injury , But not totally avoided. The method of resolving conflicts is to buy a quick charge and a slow charge. Filling fast filling with a period of time, for example, 5,10, after switching to a slow Chong Chongdian twice. This will again return to the performance of battery best.

11. Batteries are generally used when the battery pack is four or six series, this time, to maintain the balance of each battery is important, otherwise because of a battery problem affected the entire battery of work. First of all battery capacity to ensure consistent, the best choice of the same brand purchase of the same type of PCGA-BP2NX . Then, to maintain the internal battery power line, the simple, it is the battery pack, or are full, or are empty. If there is more of the battery group composed of a number of battery packs, you can try to “selected” to. Specific, that is to say, the capacity, similar to parameters such as voltage battery series into a single group batteries, due to lack of measurement under normal circumstances, after the release of End-voltage and power good voltage it.

Use the correct charger
Laptop power much greater than the phone, power need to charge the laptop battery and running at full speed machines to meet the required power supply, various models of voltage, current, or even interface is different, even if the interface is the same, if the voltage and current Lower than the nominal value of the machines, machines working at full speed when the battery may not be able to obtain sufficient charge current, battery on the damage is great. If the voltage and current much lower than the nominal value, or even find that simply can not start up or reboot it can not charge, please note that voltage and current machines must be in line with the nominal value of the plant with different products the same general interface, but Voltages and currents may be different, it must pay attention!

Batteries not to use the long-term preservation methods
Whether full or shine, in fact, are not correct, put long-term preservation of photoelectric batteries will lose their activity and even lead to self-locking control circuit protection and no longer be able to use the full power will bring long-term preservation of the safety of hidden dangers, the most Save the ideal way is to discharge to about 40 percent and save, lithium powerbook battery afraid of humid and high temperature, should be placed on a cool dry place preserved, but the temperature can not be too low B, otherwise capacity will be greatly reduced, about 20 degrees Celsius around is the ideal Save temperature.

Battery can not not change their batteries
Many people this is a battery-for-fatal, it seems that manufacturers have long been expected to do so, many brands of laptop batteries are designed with self-locking function, once the batteries out of control circuit, the circuit into self-locking state, Only the use of specific means to untie, Prior to this control circuit will not work, that is equivalent to scrap batteries, laptop batteries batteries can not arbitrarily change the batteries, if youPowerBook G4 battery batteries, batteries for specialized maintenance Companies to Caodao.

Charging not sufficient to 100% of the approach
Laptop battery exploded almost no chance, at most a high fever caused by melting shell, but rarely cause fire, was released a few incidents, in fact, the time is due to the production of non-performing, leading to short-circuit in use result, even if the Most of this will be short-circuit the battery protection circuit in the circuit will not disconnect the greater the damage, except in the protection of the circuit before the batteries short-circuit (notebook computer batteries should be that the explosion caused by this). It is such a thing in the phone number, in the final analysis the quality or battery problems, a large number of poor-quality phone battery assembly, and notebook computers rarely have such a iBook G3 battery .

The reason why 99 percent to less than 100 percent after the charge, often because the battery control circuit the battery itself and the records of the status of the deviation, the iBook G4 battery  has not reached the record in the control circuit voltage, the power control circuit has been charged, in fact batteries Has been replete with such problems can usually be resolved through the correction, but if not corrected and no relations, because the majority will be in charge circuit after a long period of time can not be disconnected automatically, or even wise automatically records the current 99 percent to 100 refresh %, Even have been the fool design, but also because the current minimum at this time and will not cause injury.

The current notebook computer batteries are basically the temperature detection circuit, when the battery temperature is too high, control circuits are forced to disconnect the battery to prevent further temperature rise, so explosive charge to such a situation in the notebook computer batteries in the No risk of no less than first prize in the lottery.
