Do you really know how to properly use the battery of the HP A2304XL laptop?

Do you really know how to properly use the battery of the HP A2304XL laptop?
So how much do you know about laptop batteries? Which unit should I use to compare the battery capacity of different laptops? What bad habits do you have when using your laptop?
We know that the battery has several important parameters, the operating voltage (V), milliampere-hour (mAh), and the watt-hour (Wh) we commonly see on the HP A2304XL laptop battery. Usually when we compare the battery capacity, we often use milliampere-hours (mAh) as the unit of comparison size. For example, when we were young, we used a four-wheel drive rechargeable battery, a battery inside the mobile phone, and a mobile power battery.
So what exactly does Wah (Wh) have to do with mAh? Let’s review the definition formula of the current in the physics class: from I=Q/t, we know that Q=It, if the unit of current I is mA (milliampere), t represents time, and the unit is hour (hour), mAh stands for The amount of charge in the battery. That is to say, if a battery capacity is 1000mAh, then when the current is 100mA, it can theoretically be used for 10 hours.
However, the voltage is not involved in the formula Q=It, so the mAh can only indicate how many Coulombs of charge the battery can hold. It does not indicate how much work the battery can do and what the maximum power the battery can provide. The above also said that the operating voltage of different batteries may be different, so there will be a number in watt hours (Wh) next to the milliampere (mAh) on some batteries.
Let’s review the definition of work done in physics class: W=UIt=UQ, the unit of voltage U multiplied by current I is W (watt), so how much work can be done is expressed in Wh (watt-hour). For example, the HP A2304XL’s built-in battery is 74.9Wh=11.42*6559mAh/1000. Therefore, we can calculate the operating voltage and milliampere time on the battery without wattage.
For example, in the following figure, the mobile power supply with a capacity of up to 12000 mAh, according to our customary comparison method, its capacity is much higher than Apple’s 6559 mAh. However, it was found by conversion that 5V*12000mAh/1000=60Wh is actually smaller than the built-in battery capacity of Apple RMBP13.
Summary: allbatteryshop.co.uk It is feasible to use the milliampere-hour (mAh) to compare the capacity of the same battery in the same voltage, but if you compare the battery of two different products, their working voltage is different, you must use Watson (Wh) is the unit comparison. If there is no watt hour (Wh) on the battery, the watt hour (Wh) can be converted by multiplying the mAh by the operating voltage (V) and dividing by 1000.

Don’t Run It Down to Empty.Full HP 729759-241 battery discharges (until laptop power shutdown, 0%) should be avoided, because this stresses the battery a lot and can even damage it. It’s recommended to perform partial discharges to capacity levels of 20~30% and frequent charges, instead of performing a full discharging followed by a full charging.
Discharge (or charge) cycles consist of using all that battery charge (100%) but not necessarily all at once. For example, you can use the laptop for some minutes in a day, using half its capacity e then fully charge it. If you did the same thing in the next day, it would be counted a discharge cycle and not two, so it may take several days until a full discharge cycle is completed.
To store a battery for long periods of time, its charge capacity should be around 40% and it should be stored in a place as fresh and dry as possible. A fridge can be used (0oC – 10oC), but only if the battery for HP 729759-241 stays isolated from any humidity. One must say again that the battery’s worst enemy is the heat, so leaving the laptop in the car in a hot summer day is half way to kill the battery.

What should I pay attention to when using the DELL Vostro V13 laptop battery?

What should I pay attention to when using the DELL Vostro V13 laptop battery?
1. Always use the laptop without plugging in the power
When using the DELL Vostro V13 laptop, some friends especially like to use it without plugging in. I feel that there is no convenience in the connection of the power cord. I often use the battery of the notebook to work until the low battery alarm is very reluctant to plug in the power. In fact, the use of these two extreme users is for the battery. Damaged.
The battery is a consumable item, as long as you work with the DELL Vostro V13 battery alone, it will be depleted. In general, lithium batteries are designed to have a limited number of cycles. A single charge cycle means that the battery is completely used up, but it does not necessarily mean that it is charged once. For example, one day you might use your laptop for an hour or more, and refill it when you run out of half the battery. If this is still the case the next day, it can be counted as one (rather than two) charge cycles, so it can take several days to complete a charge cycle.
Therefore, the number of battery cycles is often an important reference factor for the degree of use of second-hand computers, and the actual battery capacity will gradually decrease as the number of cycles of use increases, which is why the longer the battery is used, the shorter the battery life of the computer. The reason is gone. The actual capacity of the battery can reflect the health of the battery.
Therefore, if you do not plug in the power supply for a long time, you will undoubtedly increase the number of battery cycles, speed up the battery loss process, the computer’s battery life will be shorter and shorter, and will greatly reduce your laptop. The price when selling second hand.
2. Use a laptop in a high temperature environment
The operating temperature of a lithium battery is limited. Generally, the operating temperature of a lithium battery is between 0 ° C and 40 ° C. Below this temperature, the DELL Vostro V13 allbatteryshop.co.uk battery can be drastically shortened, but the battery is damaged. Not too big. However, if it is higher than the battery limit temperature, it will rapidly increase the battery loss. If the temperature is too high, it will cause serious consequences such as battery explosion.
使用笔记本电脑电池的时候有什么需要注意的呢?
In short, the battery is very hot. Therefore, when using a laptop in the summer, remember not to let the computer overheat, do not use the laptop in a high temperature environment, try to use it in an air-conditioned room. Otherwise, not only the battery is easily damaged, but the internal components of the computer are also likely to malfunction.

Sony VJS112C0811P laptop battery maintenance error and correct maintenance method

Sony VJS112C0811P laptop battery maintenance error and correct maintenance method
1. First of all, the user wants to make the notebook battery longevity, then it needs to have a good start. When we buy the notebook, the battery should have some remaining power, which is used when the user checks the machine (if the user finds the battery) If the power is full, then prove that the machine has been used.) At this time, you should not use the external power supply, use up the remaining power in the battery until it is turned off, and then charge it with an external power supply.
2. Don’t charge the battery in rainy days: It is often thundering in rainy weather. The instantaneous current impact caused by lightning strike is extremely unfavorable to the battery. In addition, a stable voltage during the use of the laptop battery is also particularly important. Sony VJS112C0811P allbatteryshop.co.uk users should try to avoid connecting the notebook’s power adapter and high-power appliances (such as air conditioners, refrigerators, washing machines) to the same power outlet.
3. Regular battery maintenance: If you can’t guarantee that the Sony VJS112C0811P battery will be thoroughly cleaned and recharged every time, then it should be charged and discharged at least once a month (ie, after filling and then refilling), or Regularly use the BIOS calibration function built into the BIOS for maintenance, which is good for extending the battery life.
4. If some users do not use the battery for a long time, then it is necessary to charge the battery to more than 50% of the battery for storage, which is beneficial to the subsequent use of the battery. In addition, in the storage process must pay attention to the indoor temperature, too high or too low temperature on the battery is also relatively large, the best storage temperature is about 20 degrees.

How to Choose the Correct HP HQ-TRE Laptop AC Adapter

How to Choose the Correct HP HQ-TRE Laptop AC Adapter
Before you buy any AC/DC laptop adapter, please make sure the AC/DC laptop adapter will give you the correct voltage and suitable current output. To find out the voltage & current, turn your laptop over and look for a label, sticker or writing which shows the voltage and current, it should look something like the examples below. The first thing to consider for the HP HQ-TRE ac adapter is the voltage. The easiest way to check this is to turn the computer over and see if there is a voltage listed anywhere on the bottom of the machine. A sticker may be affixed with this information and other similar laptop specs listed. It should be a number with a V attached to it, such as 19.5V, 20V, 16V and so om. This information is also available on the original adapter, if it is available. The second thing to look for is the current output needed for the For HP Laptop Batteries . This number will have an A of mA associated with it. For example, it may say something like 4.74A ,4.62A, 6.32A or 950mA. These numbers ensure that the power going to your machine will be acceptable and keep it operating within normal parameters. Not paying attention to either of these numbers could cause the electrical systems in the computer to malfunction and quit working altogether.

How to maintain the battery of CLEVO 6-87-P750S-4271 for the newly purchased CLEVO laptop?

How to maintain the battery of CLEVO 6-87-P750S-4271 for the newly purchased CLEVO laptop?
微信截图_20181109094815
Everyone buys a new notebook, usually there are some problems, such as the battery should not be plugged in all the time? Do you want to wait for the battery to be recharged for the first time? Regarding laptop batteries, what else do we need to pay special attention to? Today, I will discuss the problem of battery maintenance on laptops. I hope to help you learn more about battery use, maintenance and knowledge.
Most of the current laptops are built-in batteries. This time we use laptop-battery-store.com.au built-in batteries as an example. It should be noted that the internal battery of the laptop usually has its own protection circuit. Our daily use of the battery generally does not cause particularly serious damage. The battery generally calculates the life by the number of cycles of charge and discharge, and the health cycle is generally about 500-800 times, so it is not necessary to entangle the battery life protection, and it can be used normally.
How should the battery and adapter work together?
If the notebook you buy is often used for image processing or high-definition video editing, CPU power consumption will increase greatly, so the battery power will also accelerate consumption. If you often play 3D large games, it will also accelerate the consumption of battery power. The same is true for mobile phone batteries. However, the REPLACEMENT FOR CLEVO 6-87-P750S-4271 LAPTOP BATTERY laptop battery can be used with the adapter all the time. The battery capacity will naturally be lost as the number of charging cycles increases. Long-term battery charging will accelerate battery consumption. So you don’t need to use the battery to automatically shut down and recharge. When the computer reminds you that the battery is low, you can charge it yourself.
How should the battery be maintained when the notebook is not used often?
It is worth noting that the notebook will also consume power when it is turned off. If the battery stays in the unpowered laptop, the self-discharge rate of the lithium battery is high. Generally speaking, the battery is stored in the computer for a long time. In this case, the battery’s power will drop below the mortgage level, and if the battery is in such a state for a long time, it will also accelerate the battery loss.
The author suggests: If the CLEVO Laptop Batteries laptop is not used for a long time, you should keep the battery about 50% of the battery, then put the notebook in a dry and cool place to prevent exposure, chemical liquid erosion and so on. And charge the battery at least once a month. This will make your battery more durable.

MSI GS40 6QE-055XCN laptop battery does not need to be removed and put down, it will affect the battery life.

MSI GS40 6QE-055XCN laptop battery does not need to be removed and put down, it will affect the battery life.
Now the laptop can be said to be a must-have for everyone. When the notebooks of the student era are generally bought, they are vowed to use “doing homework”, “searching for information”, “writing a thesis”, and most of them are loaded with video and audio. The full range of applications and the full range of Tencent games have become game consoles and player players. The person who works is no exception. If you want to take the information home and look at it, but bring it back home, you will definitely see the news and find a movie. It will be a night.
Since the notebook computer has become a recognized necessities for everyone, how can you use this necessities to better protect your computer and make fewer malfunctions? To say that laptops are the easiest thing to depreciate, then it is definitely a notebook power supply. The notebook power supply occupies a large part of the quality of the computer, while the notebook power supply is also the energy source to ensure the normal operation of the computer during business trips. Many people feel that laptop power supply seems to be useless when the notebook is in normal use and connected to the power supply. There is even a saying that continuous charging and discharging will deplete the life of the power supply.
So what is the correct usage of laptop batteries? In fact, the most correct usage of the MSI GS40 6QE-055XCN laptop battery is always installed on the computer, do not take it down, this is also a misunderstanding of many people. Many people think that the most important reason why the notebook power supply should take off the battery is that the battery has a limit on the number of times of charge and discharge. Fully charged and then released once is called a charge and discharge, and the laptop battery is pulled out because it is plugged in. If the notebook consumes a little power, it will add a little power to the power supply. This will cause a lot of charge and discharge cycles, and the life of the laptop battery will be exhausted. In fact, this idea is wrong, the battery of the laptop does not need to be taken down.
1. Believe in laptop power management software, you can protect the battery without removing the battery.
The number of charge and discharge times is also called the number of cycles of charging. It is defined as the process of filling the battery and then running out of power. Note that the charge and discharge here are all full and all used up. The lithium battery generally has 500 normal charge. During the discharge cycle, the battery loss is negligible during this cycle. When the AC power supply is plugged in, the notebook power management system will automatically recognize and use the AC power, but only charge the power supply while using it. General computer software can do it. After all, computer is always more professional than users. In addition, the notebook’s power management generally allows the user to set the charging threshold strategy, that is, when the battery is less than a percent of the charge, charging this threshold to 50% can also solve this problem well. That is to say, only when the power is less than 50%, it will be charged, thus avoiding frequent small-capacity charging and discharging.
2. The biggest natural enemy of laptop battery is overcharge and over discharge.
When a notebook is just bought, many people will “activate” the laptop battery with their childhood experience. According to the online statement, the first three charging times must be more than 12 hours, and repeated three times to activate the battery. This is the use of the nickel-cadmium battery in the past. Most of the nickel-cadmium batteries have been eliminated. The correct way is to buy them directly and use them. If they are fully charged, they will be used. 50% charging is the best protection for the battery. Lithium-ion batteries are the most difficult to tolerate long-term over-discharge after a long period of overcharge and low power after full charge, so the charging is protection.
3. The battery power of the laptop itself is related to time. If it is idle, it will not be broken.
The lithium-ion battery used in notebooks generally gradually decreases its activity with age. Even if it is removed and not used, its power will slowly decay, and it is difficult to say that the battery is placed due to the loss of activity of the lithium-ion battery for a long time. What are the benefits of the battery? Laptop batteries are inherently consumables. Instead of letting it go down, it’s better to play its value.
4. The biggest value of the laptop battery when connected to the power supply is the regulator and emergency power supply.
The laptop battery is not useless when connected to a power source. In fact, it can be of great value. In response to a sudden power outage, the laptop battery not only protects the computer hardware and hard disk, but also helps the user save it. Precious documents, sometimes even more than the price of a battery, and the AC electrode is easy to damage the computer components when the voltage fluctuates, this time the notebook power supply can play a role in voltage regulation, reducing the impact of voltage fluctuations.
5. The appearance of the ultra-thin book shows that the laptop battery does not need to be removed at all.
The appearance of the ultra-thin book is the best answer to this question. There are many computers on the market that cannot be disassembled at all. This is because, according to the optimization of the computer, not removing the battery will not affect it.
Under normal use, the notebook battery will be reduced to about 50% of the capacity in a year or two, so don’t remove the laptop battery. It is best to use the laptop battery and play its proper value.

How to solve the problem that the ACER TravelMate 8481 laptop battery is not charged?

How to solve the problem that the ACER TravelMate 8481 laptop battery is not charged?
Recently, many netizens said that after the laptop is connected to the power supply, it can’t be charged. What happened? The four reasons why the laptop battery is not charged are the power adapter failure, battery failure, motherboard failure, and circuit failure. At this time, many computers Xiaobai did not know what to do. Mo Pan, Xiao Bian gave everyone a solution to solve the problem of laptop battery charging.
0eb30f2442a7d933036cc2aca64bd11372f0012c
When we use a laptop, we use the savings power of the notebook sequentially. After the battery is used up, we need to charge it. This time, the normal time can’t be normal, but some users have said that, but some users have encountered their own battery charge, what is going on? Below, Xiaobian will share with you how to solve the problem of laptop battery charging.
1, software problems
In general, many computer brands such as Dell, Lenovo, Sony, ACER TravelMate 8481 etc., will be equipped with power management software for their notebooks. If some kind of “battery protection mode” is enabled, the power management software will prohibit the user from using AC power. Charge and discharge the battery to extend battery life.
Therefore, if you find that your notebook is not charging, you can first enter the relevant power management software, turn off the battery protection mode or tick off the prohibit charging option, if the hardware is no problem, the battery can be charged.
2, the hardware itself has a problem
The battery’s own hardware failure, usually, we can use the computer to restart, re-plug the battery to determine, if the battery is still unable to charge, you may wish to install some hardware detection applications,  For ACER Laptop Batteries get the approximate battery loss reference information.
If it is determined that the battery hardware is faulty, do not open it or try to repair it yourself. There is a certain risk. It is recommended to take it for repair.
Security repair method:
Enter the bios when the computer starts, usually find the “start battery calibration” option in the power project, that is, “start battery repair”
Generally speaking, the user will first be reminded to connect the power adapter for full charging, and then the text will prompt the user to disconnect the AC power. The win7 system will continue to discharge the notebook until the battery is completely exhausted, after which the notebook will automatically shut down, we can Connect the power adapter for charging, but do not turn it on. After the charging indicator is off, the whole process is completed.
Precautions
Bios battery repair process may take 5 hours, so be sure to do it when you don’t need to use your notebook. If this still does not improve the battery status, then you can only say that this battery is estimated to be broken, you can send it. Repair or buy a new original battery.
