Question: The rated voltage of my original battery is 14.4 V or 14.8 V but the rated voltage of your battery of the same model is 10.8 V or 11.1 V. Is it really applicable to the computer of the same model? |
| |
| |
|
| Answer: The safe DC voltage range of a laptop is 5.5 V 24 V, which is evidenced by the power adapter equipped for the computer. The equipped battery or the original battery falls within a safe voltage range required for rated work. As we know, the laptop batteries are lithium batteries which are characterized by: The voltage increases when the battery is charged to full, and decreases when the battery is discharged. For example, the actual effective working voltage range available from a nominal 11.1 V mAH battery is 9 V - 12.6 V. The voltage is about 12.6 V when the battery is charged to full and is about 9 V 10 V when the battery is discharged. However, 9 V - 12.6 V is the effective working voltage available from the battery to the computer. With respect to the principles of DC supply design of the computer, the original manufacturer of any computer designs the supply line of the computer mainboard in that way. Therefore, the batteries are interoperable and safe no matter whether the rated voltage of the original battery is 10.8 V, 11.1 V, 14.4 V or 14.8 V. |

Question: How do I calculate the power consumed by my computer in an hour? |
|
| Answer: Such data is available from the relevant professional website. Generally, the power consumed by the computer during the running is related to the size of the computer screen, CPU, memory, hard disk and the power saving circuit design of the computer mainboard. Generally the computer screen size is 13.3, 14 and 15, and the power consumed by a standby computer is about 15WH, 18WH and 20WH respectively. Some P4 computers are defective in the power consumption design and generally consume more power. The computers prevalent in the market now are excellent in the power consumption design. The top brand computers are rather excellent in the design of power saving mode, especially SONY, IBM and TOSHIBA. |

Question: I wonder how many hours my new battery can run on the computer? |
|
| Answer: Generally, the service duration of a battery is directly related to the consumption power of the computer. For example, if the computer has a 10.4 screen and a low-consumption CPU, the computer consumes a power of about 10WH-12WH in one hour of normal service. The output power provided by a working battery is: Nominal voltage multiplied with the nominal capacity is the total output power available from the battery. For example, if the battery is 11.1 V and 4400 mAh nominally, the available power output is 48.8 WH, and the battery can run for about four hours on this computer with a 10.4 screen. The power consumed is also related to the running status of the computer. If the computer is used for playing games or DVD, the computer consumes more power in the full-speed running status, and the service duration of the battery is shortened accordingly. |

Question: My battery works for three hours initially, but then it cannot be charged further. Is the battery faulty? |
| |
|
| Answer: Operate according to "Calibrate your laptop battery to optimize its performance" described above. If the problem persists, consult the local distributor. |
|
Question: Why does the computer display completion of charging only 10 minutes after start of initial charging the battery? |
| |
|
| Answer: Operate according to "Calibrate your laptop battery to optimize its performance" described above. If the problem persists, consult the local distributor. |
|
Question: The battery volume is displayed as 30% after the battery is initially charged for several hours. Why? How can I charge the battery to 100%? |
| |
|
| Answer: Operate according to "Calibrate your laptop battery to optimize its performance" described above. If the problem persists, consult the local distributor. |
|
Question: My battery makes the computer shut down directly without alerting or changing into the hibernation status. This occurs for several times in a few minutes after the battery is charged to full. Why? |
| |
| |
|
| Answer: Operate according to "Calibrate your laptop battery to optimize its performance" described herein above. If the problem persists, consult the local distributor. |
|
Question: When I put the battery into the computer, the computer shuts down automatically; when I take the battery out, the computer works normally. Why? |
| |
|
| Answer: That indicates the battery is faulty. That occurs rarely and is possibly caused by technical faults arising from short-circuit protection of the battery interface. In this case, contact your distributor to replace the battery. |
|
Question: The battery does not work and the laptop powers off immediately after I disconnect the AC supply when the battery is charged to a certain percentage or even 100%. Why? |
| |
|
| Answer: When this problem occurs, check whether the ambient temperature is too high. If the laptop is used in a high-temperature environment for a long period, the battery will be disconnected for purpose of protection. In this case, in order to prevent accidents, shut down the laptop first, take out the battery, and then reload the battery. Another possibility is that your computer is faulty in the process of charging. In this case, check the computer because the charging circuit of the computer tends to fail in case of charging. In this case, use the original battery instead and check whether the computer works normally. If the problem persists, contact our distributor to replace the battery. |
|
Question: The electricity volume is still displayed as 0% after my battery has been charged for 20 hours; and the computer is powered off immediately after the AC supply is interrupted. Why? |
| |
|
| Answer: First, check whether the battery contacts the laptop properly. Improper contact makes it impossible to charge the battery even if the communication data of the battery is readable. In this case, try to unplug and plug the battery for more times. If you hear a clatter after inserting the battery into the laptop, it is generally regarded as proper contact. Try inserting for more times, and you will know whether the laptop contacts the battery properly. Pay attention to this especially when you use an IBM laptop. If you are sure that the battery contacts the laptop properly but the battery still does not work normally, the battery may be substandard. This problem is caused by two factors: (1) The line board of the battery is damaged or short-circuited; (2) the battery may be incompatible with your laptop, which is a technical problem and needs to be solved by us. Please contact distributor to check the status of the battery. |

Question: Is the battery life reduced if the battery is charged before being exhausted? |
|
| Answer: The calculation of the battery life is based on complete cycles of charging and discharging. The life of a lithium battery is generally 300-400 cycles. You do not need to worry whether the battery is charged for a cycle once the AC supply is connected. Only a complete cycle of charging or discharging counts as a cycle when calculate the battery life. |
|
Question: Do I have to remove the battery when I use the AC supply? |
|
| Answer: Generally, the charging of a laptop battery begins only when the electricity volume is lower than 95%. Due to existence of natural consumption, the battery consumption is basically the same no matter whether you remove the battery or not while the computer is working. However, we recommend you not to remove the battery while operating the computer because this prevents the data loss in case of abrupt interruption of the AC supply. If you remove the battery, wrap it into a fresh keeping film and put in a dry and cool place. Remember to perform a complete charging and discharging cycle for the battery every month to prevent the battery from losing activity. |
|
Question: Why is the electricity reduced before the battery is put into use? |
|
| Answer: Due to influence of ambient humidity and non-insulated environment, the battery is consumed naturally. Depending on the newness and quality of the battery, the electricity of the battery is reduced by about 1% in 3-4 days. Therefore, a moderate reduction of electricity is normal. |
|
Question: How long can a new battery drive the laptop? |
|
| Answer: It is difficult to determine the operation time of the laptop battery. The actual operation time depends on how much electricity is required by the device. The screen size, hard disk and other accessories may consume extra electricity and shorten the operation time. The total operation time of the battery also depends on the design of the device. Generally, a battery of a standard volume is designed to drive the computer for more than two hours. |
