It is so bad to be confronted with power failure in the process of work, especially for some urgent or important conference and business projects. As to some places without power energy, it is even more important to extend the laptop life and standby time.

power failure, laptop shut down

To avoid data loss by long life laptop battery with longer last time

As to power failure situations, the most seriously consequence is to come across data loss. Therefore, we need to ensure that laptop computers have enough preparation to deal with this kind of situations.

As long as you have enough power energy to support a 5-6 hour conference, most of business projects can be covered as long as you have got such a high-quality battery. Of course, we need to have some proper setting in power options to indicate when the remaining power is about 20% or more and automatically power off or go to sleep in about 10% or more. All these can help you to get rid of data loss and damages in laptop system.

How to check if the certain battery is of long life?

What we talk about is the long life laptop battery that has longer standby time. When selecting a backup or replacement, the most important factor is the output power that has determined the actual work last time.

Compared to original standard battery versions, they usually have the same output voltage but higher output current that has higher internal capacity and more power energy to supply in the process of charging and work.

Anyway, users should ignore the quality, compatibility, security, stability, after-sale service and warranty when buying a brand new long life laptop battery. We are firmly convinced that you will be satisfied and get more success thanks to longer standby time.

As a matter of fact, except for installing and usage, some other aspects about laptop batteries are of great significance to battery performance. That is storage. In most cases, proper storage methods can improve the battery performance to a great extent. Otherwise, some damages like leakage of electricity and poor weak power functions are likely to occur one day.

laptop batteries, storage

How to unplug the laptop batteries?

Usually, we remove the laptop batteries if the computer is out of use for days or months. After all, the connection of interface is possible to discharge more power energy and improper places will lead to some dangerous situations. Therefore, users should unplug the laptop batteries carefully and make it cool down before putting into the right box. And please ensure the laptop charger is unplugged and computer system is power off before having any operation.

What is the suitable site to place laptop batteries?

After unplugging, the next step is to look for a right place for the lithium-ion laptop battery. We recommend users to select a cool and dry box that can avoid deep discharge and any other factor like high temperature to influence on battery performance.

How often should we use the backup batteries or recharge unused ones?

Even if is proper stored, long-term not in use is also harmful to laptop batteries and other lithium-ion batteries. If possible, please recharge it or play with your consumer electronics with them at least once a month to activate the system monitor and indicator and internal structure of the battery.

When will the laptop batteries come to be weaker if used properly?

Usually, battery doesn’t have the same lifespan as the whole consumer electronic product. According to research, a brand new high-quality lithium-ion laptop battery runs into weaker after using for about 2 years and can last for 3-5 years.

If you have accepted a mission to establish a new battery management system with design monitor system, you need to take advantage of some strategies to optimize the design cost and manufacturing ability. The initial issue about how to ensure the system primary internal structure and batter related electronics location. The final goal is about how to achieve the final communication and connection or system and lithium-ion battery.

Lithium-ion battery

The appearance of lithium-ion battery has great significance to power system internal structure. It is necessary to take use of large amount of batteries to be adapted to the completed battery pack or we can use some large sized batteries to limit its quantity and size. Maybe it is the most important part of circuit design as the innovative battery appearance is booming out with time goes by.

Another factor to consider of is about battery pack, battery management system and the final application interface, testing signal and remote connection. In most cases, it is likely to have a shell for these lithium-ion batteries to be connected with data collection circuits, which can reduce the nominal value of output voltage and wire quantity.

Under the damage situations, the output voltage of lithium-ion battery is usually below 200V. By this method, the maintenance man can get rid of dangers effectively. As for battery packs of large size, we need to apply with two types of data selection system to support 50 battery interfaces.

There’re also some other factors to influence on physical structure and monitor circuits. As to lithium-ion batteries, it is necessary to keep balance in order to avoid some extra heat problems. Meanwhile, if you need some power switch, the temperature monitor interface can supply a kind of voltage reading and power supply status to be connected with each other. In the process of design, the most common considering factor to be ignored is the leakage of electricity. Therefore, extra control circuits are important.

All is all, in battery management control circuits, we have great number of factors to consider, especially for determining pack limited factors. When the pack design minds are connected with each other, we need to consider of some possible mechanical effects. Once we have get balance between pack and internal structure, the solution for lithium-ion battery is born out.

Laptop computers have become an indispensable part of our daily lives in recent years. Portable, highly functional and versatile, they’re the number one choice of dealing with everyday tasks of businesspeople and ordinary people in their daily activities.

Due to their importance in our daily lives, one critical aspect of evaluating a laptop computer—batteries—seems even more important when we try to buy a laptop computer and use it for quite a long time. Battery life, as is known to many, is a parameter used to determine the time period during which a laptop computer can function normally. Usually, laptop batteries can sustain a laptop computer for 3 to 4 hours, depending on the specifications of a laptop battery and the power needs of the computer and the programs the user runs. Lithium-ion batteries are common nowadays. They are one of the most popular types of rechargeable battery for portable electronics like a laptop computer.

laptop battery

How to decide if a laptop battery is high-quality? Here are a few key parameters: volt, capacity, and battery type. Another important thing to consider when shopping for a laptop computer or a replacement battery is the amount of cells contained within a laptop battery. Usually, there are two sorts of battery cells: 6 cells and 9 cells. The more the cells, the more capacity the battery has. But more cells also mean your laptop is heavier. So if you are the type of persons who carry laptops with you almost all the time, the battery cell number is a big concern.

Great care should be taken to increase the battery life of a laptop computer. Dimming your laptop screen is one of the best and easiest ways to increase your laptop batteries run time. Turn off your Wi-Fi wireless and Bluetooth if not needed. Tweak your computers power options. Don't play computer games, music CD's or DVD movies for multimedia activities drain laptop batteries quicker than ever.

At first, it is related to lithium-ion cells and other electronic accessories, which may also influence on communication and connection.

In some cases, the appearance of lithium-ion laptop battery is also of great significance to power system internal structure. Comparatively, a large amount of lithium-ion batteries with complicated battery mode or pack. Therefore, due to weight factors, the battery quantity and size are limited by design and it will also become the limitation to battery capacity.

In addition the battery mode and pack have also got great connection with battery management system, signal connection and remote signals. Then it comes to the certain mechanical concept design. In some mobile cars, generally speaking, there’ll be more than 100 battery indicating and calculating spots on the average. The servicemen usually take use of voltage lower than 200V to reduce the possible dangers in the process of work.

Other factors many also lead to physical and monitor battery circuit problems. As is exemplified as lithium-ion laptop battery, we need to keep it work in the balance state. And temperature monitor is also necessary to be connected to voltage to check the charging state. Therefore, we need to have some support and connecting plans to control these circuits in case of leakage of electricity and other dangers.

All in all, battery management system has many factors to consider of, especially for those limit capsulation. As long as these problems can be solved with each other, the indicating system can be compatible to lithium-ion laptop battery very well.

Many users are not so clear about the proper battery usage methods and maintenance tips. With time goes by, the battery capacity comes to be decreased rapidly while we cannot play with our laptop computer for many hours as it did in early times. To make users more clear about them, we have had an experiment about laptop battery.
laptop battery capacity

First of all, we have adjust the setting of power in options to maximum the power energy consumption in LCD screen, minimum the CPU running rate, and then adjust hard drive, standby, sleep and screen protection mode to be never. After that, make the laptop computer to be shut down automatically when remaining power is only 3%. At last, unplug the laptop charger and any other USB devices and restart the computer.

After the laptop computer has opened, you can play with it flexibly, but please don’t run any program, including laptop battery indicating software, to fully discharge it until shut down automatically.

In addition, please remember to charge the laptop battery when it is closed. As a matter of fact, this circle of fully charging and discharging can get back battery capacity to some extent while it is reasonable to have such operation for several times.

As to those old laptop batteries, we recommend users to have thus circles of activation for about 3 to 4 times.

Of course, please avoid deep discharging laptop battery. Otherwise it will be very harmful the battery performance. Meanwhile, battery indicating software cannot have accurate test on these batteries of 100% accuracy. All in all, we should take good care of these laptop power supplies to improve our work efficiency.

As for some large business conference or trip, it is hard to find a suitable outlet available at any time. It seems that we cannot get enough power energy from laptop computer all the time if power cord is not connected. And for business trip aboard, switch socket is also necessary to fit with different plug and mains supply.

large business conference

Extended life laptop battery, the essential item and business helper for large conference

If you need to deal with your work or have some records during a whole day conference, it is really impossible to last long enough with a regular 6-cell or 8-cell laptop battery. Unless a outlet is available in time, we are at risk of data loss, lack of power or other dangerous situations run into our notebook computers in no time.

Comparatively, extended life batteries of 9-cell, 12-cell are more effective that can not only expand the battery capacity to last longer in standby time but are able to provide higher work efficiency as well. Thanks to more lithium-ion cells inside, laptop computers can get higher output current from the higher capacity batteries.

Some users are not used to these extended life laptop batteries as they are usually longer or larger in shape. As more lithium-ion cells are installed, batteries should be expanded to accommodate these additional cells.

In business conference, usually we don’t need to move frequently while the thick bottom can also facilitate us to type or work more conveniently in the process of meeting.

For business trip, global compatible laptop AC adapter is also the essential item for luggage. As is known to all, different nations have different mains supply from 100V to 240V. And the laptop chargers in USB Phone World are all with switch mode that can fit these mains supplies well.

How to take different photos within 3 minutes during fast-paced travelling? When I am willing to take photos, the first step is to reduce exposure compensation which can help you to get back some light details. T he clouds in the sky and the image reflected becomes clearer and having more layers .It makes the color sharper. Of course, you can also try to use gray gradient filter to find the arrangement of sky.

It is necessary to save the battery power during your travel. At first, you have to try your best to avoid the unnecessary zoon operation. We advise you to move your camera to get the same zoon effects if you really need zoon.

The second way is avoiding using flash frequently. You had better not take flash as flash usually consumes lots of power. Meanwhile, using viewfinder is better than liquid crystal display when you adjusting the image.

LCD also costs high power so you had better not take it so frequently because normal photography could be operated by viewfinder. Actually most of the digital camera alkaline batteries will be open for LCD that consume more power, will close it can make a battery spare time growth two or three times.

Of course we should not abandon LCD as it is very important part when you take close photography. Finally please keep your camera close when you do not take photos.
At last, taking an extra full-charged battery should be the most necessary tool.
