A: If you encounter this problem, you can correct your laptop battery as described in Section 3 to achieve the best performance. If you still can't solve it, please contact your supplier to request a replacement.
A: The running time of the laptop battery is difficult to determine. The actual running time depends on the power requirements of the device. The size of the screen, the hard disk and other accessories consume extra power, which greatly shortens the running time. The total running time of the battery also depends on the design of the device.
A: The battery life is generally calculated according to the number of full charge, and the lithium battery is generally 300-400 times. Of course, you don't have to worry about charging the battery once when you turn it on. The number of times the battery is charged will only increase once when the full charge and discharge is completed.
Answer: (1) It depends on whether the temperature of your working environment is too high. If it is used in a high temperature area, the battery will be protected for a long time. In order to prevent accidents, the computer startup program will terminate the computer work. At this time, you can Turn off your computer and you can remove the battery and put it back.
(2) The charging circuit of the computer is the most prone to the problem of charging when charging. Another possibility is that your computer has a problem during the charging process. Please check your computer. At this point you can find the original battery and see if the computer works.
A: This message indicates that the battery is not compatible. When such a failure occurs, please contact your supplier for a replacement.
A: This indicates that the battery is faulty. This situation is very rare, probably due to technical problems caused by short-circuit protection of the battery interface. In the event of this failure, please contact your supplier to request a replacement battery.
A: When all laptop battery manufacturers ship, the laptop battery will charge 40-50. Generally we recommend charging all night (about 12 hours). The initial use of the new laptop battery should be cyclically charged (deep charge, then deep discharge) 3 to 5 times to optimize battery performance. (Note: It is normal for the battery to have a certain temperature during charging and discharging). New batteries are difficult to charge with adapters because they never charge deeply. If this happens, remove the battery and reinsert it. The charging cycle should start again. This may happen multiple times during the first battery charge. Don't worry, this is completely normal.
A: A laptop, which operates from a DC safe voltage range, is between 5.5V and 24V. The batteries we supply are all within a safe voltage range required for rated operation. As we all know, the batteries we use are all lithium-ion batteries, and the characteristics of the lithium-ion battery itself are: the battery voltage will increase when charging; the voltage will decrease when the battery is discharged. For example, a battery with a nominal 11.1V can provide an actual effective operating voltage range of 9V-12.6V. When the battery is fully charged, the voltage is about 12.6V, and when the battery is discharged, the voltage is about 9-10V. Between 9V-12.6V is the effective working voltage that the store can provide for computer work. From the design principle of the DC power supply of the computer, all the notebook manufacturers design the power supply circuit of the computer motherboard, so the nominal voltage of the original battery you are using is 10.8V, 11.1V, or 14.4V. 14.8V, can be used interchangeably, and are safe, please feel free to use.
A: There is a microprocessor software inside the laptop battery that can estimate its power during charging and discharging. The battery needs to be calibrated from time to time to ensure that the screen display time and percentage are correct. You should do this the first time you use your computer, and do it every few months.
(1) First set the "Power" option: right click on the blank space, select "Properties" - "Screen Saver" - "Power" - "Power Scheme" - "Portable / Pocket", then Select "Never" from all the options in "When Computer" "Use Battery", and cancel the "Battery Low Alarm" and "Battery Critical Shortage Alarm" functions under "Alarm".
(2) Disconnect the power adapter and use your battery until the computer is completely powered off.
(4) Connect the power adapter until the battery is fully charged and 100%. At the first use (or after a longer period of storage), the battery needs 3-4 full fill cycles to achieve its optimum performance, and the charging process takes at least 14 hours.
(1) You must first discharge your battery until the computer is powered off and then fully charge it to 100% to correct it. After that, you can connect or disconnect the power at any time regardless of the battery level. In addition, you can do a deep charge and discharge under the control of the protection circuit for a period of time to correct the battery's power statistics, but this will not increase the actual capacity of your battery.
(2) When the battery becomes "empty", the computer is forced into sleep mode, and the battery actually retains a certain amount of power to ensure that the computer can sleep for a while. When the battery is completely drained, the computer will be forced to shut down. At this point, any open documents will be lost.

A: Due to the influence of environmental humidity and non-absolute insulation environment, the battery has self-consumption phenomenon. Depending on the age and quality of the battery, it will drop by about 2% in 3-4 days, so it is normal as long as it is not a large drop. phenomenon.
A: We recommend not removing the battery, which prevents the ongoing operation of the AC power supply from continuing in the event of a sudden interruption without losing data. If you remove it, it is recommended to wrap the battery in the plastic wrap and place it in a dry and cool place. Remember to use the battery at least once a month and charge it to avoid loss of battery activity.
A: First of all, check if the battery and the notebook are in good contact, because if the contact is not good, although the battery communication data can be read, the battery cannot be charged. . At this point you can take the battery out and try it a few more times. If you insert the battery into your computer and you hear a beep, you can basically think that you have been in good contact. Try a few more times to eliminate the problem of poor contact between the computer and the battery. Especially when using an IBM computer, pay attention to this problem.
A: Please follow the steps below to charge and discharge the battery.
(1) Put the newly purchased battery into the laptop (2) Disconnect the notebook adapter and use the laptop until it automatically shuts down. This is a deep discharge process (3) connection adapter, the battery starts charging (4) charging until the battery is full (5) repeated charge and discharge cycle several times, your battery will reach the highest performance
A: There is a self-approval process when the new battery is first charged. After a while, it will show normal. Please set the power meter management system for the minimum power required for the computer to shut down. Disconnect the adapter and use the computer to know that the battery is fully used. Then connect the adapter to start charging. The battery is deeply charged and discharged or cycled 3-4 times to ensure optimal battery performance.
A: Generally, the usage time of a battery is directly related to the power consumption of the computer.
For example, a 10.4-inch screen computer with a low-power CPU, then the power consumed by this computer every hour is between 10WH-12WH. The output power that the battery can provide is calculated as: The voltage is multiplied by the nominal capacity, which is equal to the total amount of power that the battery can provide.
For example, a notebook battery with a nominal 11.1V, 4400mAh can provide 48.8WH of power output, so the normal working time of the battery on this 10.4-inch computer is about 4 hours. The power consumed by the computer is also directly related to the state of use of the computer. If you are playing a game or watching a DVD, the power consumed by the computer at full speed will increase, so the battery life will follow. Shortened.
Answer: (1) If you want to keep your laptop battery stable, you must always work independently with the battery. If the battery is stored in a closed circuit for a long time, the battery will be damaged.
(2) If you do not use the battery for one month or longer, it is recommended to take the battery out of the computer, charge it to 60%-80% and store it in a dry, cool and clean place. If not used for a long time, the battery's power will eventually be lost and damaged. It is therefore necessary to charge the battery after a period of storage. Of course, if you can use it once a month, you will be able to better ensure that the battery is stored.
