I have seen you online frequently asked questions related to notebook batteries Laptop Battery are summarized as follows, Let us help!

Q: Laptop battery long-term need, it should be how to preserve?
A: Charge or discharge to about 40%, and then placed in temperature of 15 to 25 degrees Celsius dry preservation, the temperature is too high and too low are easy to accelerate cell aging.

Q: The battery does not remove the books to each power supply will you?
A: It does not matter, the laptop battery protection circuit again, full of will not continue to charge the

Q: My battery
Apple Laptop Battery is now only a very short period of time, how should I do?
A: If you've been in the frequent use of the battery, then it belongs to cell aging, which can not be avoided, you can only consider the change a new battery or if the replacement batteries batteries; If you do not have battery long-term, may also lead to this phenomenon, this time need to completely discharge (up to fail to boot up) and then full power, repeated several times to activate the battery.

Q: laptop universal power adapter can do?
A: No, there are three obstacles, the first is the notebook computer manufacturers use various different voltage, such as IBM are 16V, COMPAQ mostly 18.5V, SONY part of the model is 19.5V, are inconsistent. The second is different from the needs of current laptop is different from the 2A ~ 5.4A have a small machine needs a smaller current, big machine in the latter case. The third is the various manufacturers notebook power adapter interfaces are different, it is difficult general. Therefore, at present do not yet common to all the notebook power Compaq Armada E500 Battery adapter

Q: How should the new machine bought charging it? How do I maintain the battery?
A: Lithium (ion) battery is the need to maintain a certain electromotive force to maintain its internal chemical activity. Therefore, to achieve full charge when the full release, in general, the first three can be a period of about six hours of charge time will be tight, like electric charge to 100%. To avoid the use of point charge, less than 10% of the time to charge a timely manner and not to be exhausted, so that the battery but there is injury; also higher than 60%, also try not to charge. A long time without battery applied to about 50% of electricity at room temperature and dry environment preservation.

Q: Why does my IBM laptop Compaq Presario 1700 Battery is always in use when the battery power than with the low brightness when a file?
A: This is the IBM default settings for random power management is aimed at energy-saving:), if you do not like it, you can control software in IBM's ThinkPad Configuration Utility, select LCD project, then changed to High brightness from Normal can be. The Display option in the BIOS which have the same settings. In fact, the purpose of doing so is to power.

Q: first use of laptop batteries, the first three to be recharged in 12 minutes?
A: This is not necessary because the current laptop has a sound management of electrical power
Road and charge management system, when the battery reached saturation, the control circuit will automatically switch to the circuit state,
Thus, even in sufficient time for however Compaq Presario 900 Battery long to no effect.

Q: In order to prevent memory effect, we should run out before electric charge do?
A: Every time charge of battery discharge is not necessary, but also harmful. Practice has proved that the battery deep
Degree of discharge will shorten the life of unnecessary, it is recommended to use when the battery is only about 10% when you can charge
Power of the. While the battery is still in power more than 30% better when you do not charge, because the memory effect is indeed
Exist more or less real.
On the laptop battery

Notebook emphasis on mobility, laptop battery is one of the key, the use of time has become increasingly the subject of attention, the author collected some information about this Compaq Presario 700 Battery laptop battery information, and share with you

Let's start talking about the battery materials, batteries used in notebook computers there have been three types: nickel-chromium batteries, nickel-metal hydride batteries, lithium batteries; they are generally expressed as: Ni-Cd Ni-Cd, Ni-MH Ni-MH, lithium Li.

The first is to use the notebook computers Ni-Cd nickel-cadmium batteries, nickel-cadmium batteries because it has many drawbacks, such as: bulky, heavy weight, capacity, small, short life, there are memory effect and so on. As well as nickel-cadmium batteries have been eliminated, does not make sense to discuss it, we all know what to do.

There are now battery-Li Lithium-Ion battery Compaq Presario 1800 Battery and Ni-MH Ni-MH two kinds.

Lithium-Ion battery has a small size, light weight, large capacity, low memory effect, charging the advantages of a short time, a very welcome, but some people believe that there is no battery memory effect is wrong, it is irresponsible to mislead the merchants. Similarly, lithium batteries have memory effect, but its relatively low memory effect, but not very noticeable. If there is no memory effect, then, in many articles on the maintenance of laptop battery should be regularly referred to "full discharge", "long useless to re-use to activate the battery" and other recommended Kai is not nonsense?

In a senior engineer I learned that in fact can be divided into two kinds of lithium batteries, a lithium electricity, the other is the lithium-ion batteries. Lithium-Ion battery in the early days there, but it is not safe when used often in charge when burning, bursting, it is because the lithium is too active reason. Then there is the improved version of the "lithium-ion batteries", which joined the element lithium can inhibit the active ingredients, so that lithium really achieve safe, efficient and convenient. While the old lithium battery and therefore eliminated. As to how to distinguish them from the battery's label will be able to identify, lithium battery for Li, lithium-ion battery for Li-ion. Now, laptops to use the so-called lithium, in fact, lithium-ion battery. Lithium-ion battery charge and discharge times in Compaq Presario 1200 Battery the 400-600 times, specially modified products, but many times 800. If the charge once a day basis, the best lithium battery life of nothing but more than two years, so laptop battery warranty period is the longest of this year is also the reason

Ni-MH battery is the most environmentally friendly battery, pay attention to environmental protection, countries have been vigorously promoting the use of nickel-metal hydride batteries, because the ease of recycling, and the damage to the environment are minimal. However, nickel-metal hydride batteries and lithium compared, there are still some disadvantages: charging for a long time in weight than the sink capacity than lithium is small, there is a strong memory effect. It is the memory, while not as big as nickel-cadmium batteries, but still need to discharge, the user must be exhausted before charging. However, the number of Ni-MH rechargeable batteries Compaq EVO N620C Battery can be achieved for more than 700 times, some good quality product charge and discharge up to 1,200 times, more so, and lithium-ion battery, Ni-MH battery live longer than the lithium batteries, but also the price of nickel-metal hydride batteries have is much lower than the lithium batteries. This is the nickel-metal hydride battery can be the reasons for market share corner bar.

Currently on the market, whether it is lithium-ion batteries or Ni-MH battery, its capacity sizes are based on mAh as a unit, its Chinese name is mAh. MA hours directly related to the size of the notebook usage time. But not the larger laptop battery the longer, which also linked to the notebook's components to decisions, such as: CPU, graphics card and so on, using the Centrino CPU, ATI-MOBILITY RADEON graphics cards and many other energy-saving technology the hardware and the use of P4 CPU, NVIDIA notebook graphics card, compared with the same capacity Compaq EVO N610C Battery battery, the former use of time much longer than the latter.
Laptop battery failure causes and preventive measures

Laptop battery maintenance, from the start with two parts, one battery pack circuit board and batteries within the core (hardware), and circuit boards, various battery parameters stored information (software).
The hardware part of the fault, generally can not be maintained as a part of the circuit board burned out, or a battery cell is damaged, usually beyond repair on the grounds that most of the existing notebook computer batteries have to glue way to packaging cell group, after its plastic bonding, to use the external damage apart, their plastic shell will certainly be damaged, and in the open the process, may cause short-circuit the battery core or circuit board, causing more serious damage, so As long as the hardware part of the failure, is usually recommended that users buy a new battery.
However, some laptop batteries are in the early screw to encapsulate the battery, for hardware damage, repair is feasible.
The software part of the maintenance: battery operation, in fact, there are many parameter settings to the host computer to communicate with the laptop, the brand used by the IC and software different, but the main heading for power management, so that the battery in the use of the security situation , the effective use of each sub-electric power, but some misuse of the situation, or the placement of the battery for too long, and its own bias, making a mess of this parameter setting, so that some brands of notebook Compaq EVO N600C Battery models will be added in the design a battery of self-correction procedures, the implementation of the program, the battery will be automatically adjusted to the best condition, if the same can not solve the problem, it would be back to factory inspection.
