The things we should aware when using the laptop battery

LAPTOP Battery Description: Currently, the use of lithium batteries for laptop mostly, though there Lithium battery is better than many other advantages, such as the absence of memory effect, high capacity battery, charging time is short and so on, but it is also more valuable and limited life electronic components. Under normal circumstances, the number of notebook battery charge and discharge also in the 800.

In accordance with the guidelines of the IBM manual on basic use of the relevant part of finishing the knowledge of the battery:

Use the correct power cord and AC adapter (laptop ac adapter) saying goes, is the processor. The main sections are the following:

1. To avoid the use of non-confidence in power, to avoid unstable power laptop burned;

2. To prevent fluid contamination by lead adapter to short-circuit;

3. To avoid power lines across the aisle, both easy to stumble upon another, but also easily lead to poor nutrition has been violated;

4. Avoid using packaging other packaging of the power adapter, resulting in problems of heat dissipation. Battery and power adapter to maintain good ventilation and heat dissipation.

5. Using the power corresponding to the product manufacturer and battery. Do not use third-party solutions. This laptop easily lead to damage or can not play the best performance.

6. Do not attempt to open or maintain the cell (excluding professionals), because the control circuit of the battery within the accuracy of violence likely to cause damage to precision circuits.

7. Do not be such as batteries and keys scattered together a metal material to prevent accidental short-circuit the battery.

8. In bed, sofa, carpet and other soft surfaces when used in laptops has been careful not to obstruct heat dissipation.

9. In accordance with the relevant web site describes the battery charge and discharge summary and the normal use of the technique. Because Laptop batteries lithium-ion battery manufacturers in different production processes are different, so the battery inside the control circuit has its own characteristics, and this tour will not hesitate to adjust the state information, battery therefore in accordance with the instructions on the laptop recommended load and discharge method is to use the battery is the best. It is better to keep a full load (Automatic Red State notebook End) to fully discharge (used in stand-by) such a condition.

10. If there is a situation of external power, it is preferable to remove the laptop battery and unplug the external power supply is connected to a charge-discharge process, which can lead to Li-ion battery inside the battery status in the analysis when the circuit is disrupted.

11. If no long-term use of laptop batteries, must be made each month, a full charge and discharge, to maintain cell viability. In addition, if long-term (year) not to use the laptop battery should be charged 50%, and the charge once a year to avoid excessive discharge of the battery. If the charging time of the arrest may produce better results, but does not require to be stopped.

12. If you can load 30 minutes after the completion of the reuse of the battery may have a better battery.

13. Ships with installation of mobile software power management to better play the role of the Dell Inspiron 1501 battery and battery protection.

14. Do not use the display too bright LCD, under normal circumstances do not need the LCD display mode brighter, so we do not feel brilliant, but also extend the life of the LCD, the same will not see the light “annoying background.” The best in different working environment to adjust the brightness of the right to protect the view.

Finally, the Key Tips: laptop batteries contain lithium, if used or handled properly, could be an explosion.

How to correctly charging laptop battery

In Laptop battery using process, do not deliberately request to 100% charge, or use completely without electricity untill automatic shutdown, the correct way is to begin to charge about 20% , stop charging  about 98% full. If the machine has the power calibration procedure, then you can calibrate the battery when you feel significantly reduced power consumption, so that protection circuit can fully work. For early notebook batteries (Ni-MH or Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity, but for the lithium battery, it is not necessary but may damage the Dell Inspiron 1501 battery. It is said that lithium batteries have no memory effect, in fact it’s not entirely correct. It’s only a very small memory effect. Materials for lithium battery are very sensitive to the temperature, the use frequency and so on. After using for a period time, the battery will be aging, the performance of the most intuitive is the reduction of using time.

The natural ullage is an important reason, and inadequate maintenance is another important reason. A well-designed lithium battery has a very good protection circuit to prevent excessive charge and discharge. For over-charging and discharging of the hp 361742-001 battery will rapidly reduce the battery activity. Because of the role of the protection circuit, the user repeated several times to fully charge and discharge, in fact, it is impossible to achieve “full” level. It does not make sense to do so. Sometimes WINDOWS show there is 20% of battery capacity, you can use 30 minutes, but not long after, suddenly the machine automatically shut down, this is because the battery has been aging, the battery protection circuit can no longer monitors the real capacity of the battery. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery, so the power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity of the battery. But this correction process will often take two or three complete charge and discharge, and as previously mentioned, fully charge and discharge will reduce the Dell XPS M140 battery activity, so please not frequently used.

How to ascertain the lithium iron battery quality

Lithium-iron Laptop battery by using different materials and processes as well as rigorous quality control to varying degrees, but it was a big difference. In particular, greater price difference. The prices between high and low are almost twice.

Why is there such a difference in Na? So why lithium iron batteries will be so good cheer? Where is the difference? How to choose?

The production of lithium-iron battery and environmental requirements of the production process are more stringent, a neglect of non-performing rate slightly will improve immediately reduce the price it had lower standards. Because of this, some grade B or C grade will flow on the market. As lithium-iron Dell Inspiron 1501 battery is still a relatively new, many buyers today do not know whether it is also, therefore, wishes to provide some distinguishing features of this method and the importance of the battery for your reference.

Lithium-iron battery is good or bad judgments, the most basic points that can be analyzed from the following:

1. Uniformity

Battery harder to do is homogeneous, but the largest chain of battery is also homogeneous. If the 10 batteries strung, there is a first to arrive on-protection standards of the discharge, while several others are still plenty of power, this string of hp 361742-001 battery pack that can power capability is not all over low? Were made with a first place is the same reasoning.

The inconsistency of the battery without the added protection board is very easily broken, it is easy to overload or excessive discharge; have unprotected board sony VGP-BPS2A battery pack may be using more electricity capacity will also be more weak. There is also a lot of battery factory launched the production of batteries, but it was not necessary for the chain of causes product group. And the whole manufacturing process is very strict to achieve uniformity in controlling.

Simple Test Method: Series 4 batteries, so 1C and 3C charge-discharge, and the concept of charge-discharge process of the investigation, the battery voltage to see if differences in the lifting of the situation will. It is better to do 4 to 5 times.

2. Self-discharge rate

Lithium iron battery self-discharge rate, the theoretical value must be less than 2% per month over this value is not a good Dell 75UYF battery. Not a problem in the method is to use the material in question.

Low-rate self-discharge has always been the characteristics of lithium-iron battery, if self-discharge rate, when you install finished goods delivered to customer sites, he had no power, and customers feel? And a lot of energy wasted.

Channel in the group context, it will affect the balance of the hp PB992A battery, the battery can be installed less, and that the battery life is reduced.

Method of simple test: take roughly equal to the capacity of the battery 10, the congestion charge put aside for a month after switching on, then measure the value of the ability to calculate the self-discharge rate. (The sets aside a call after that amount of voltage value, what changes in battery voltage.)

3. Charge-discharge rate (load C-rate)

Quick charge and discharge is actually a lithium-iron batteries, one of the most advantageous because of its fast charge and discharge, which has very similar characteristics and a super capacitor but its super-capacitor capacitor important than hundreds of times. If the charge-discharge characteristics sufficiently rapid, the use of lithium-iron apple A1079 battery is not very meaningful.

In general, the charging rate of good quality lithium-iron battery is 3C (about 20 minutes power saturation charge), while the speed can reach 30 degrees centigrade. Special needs can achieve a higher magnification of the charge and discharge. The above situation is quite the battery life is the premise.

Method of simple test is, in order to manufacturer specifications can be used to test the maximum load, the rate of discharge, if the testing process, the cells fire very serious, then the quality of BTP-43D1 batteries n is not very good.

4. Stages

In general, the user can not be measured, and can only trust the data supplied by the manufacturer or appointed by a professional unit on behalf of the measure. Good quality lithium-iron batteries, in 3000 the use of 1C charge cycles and discharge its electricity capacity; mitigation will be less than 15%.

In short, the lithium iron Dolphin alone, the problem spots are not large, but after the series parallel connection to use and the features described above should give special attention to the. Especially in the high strings high voltage VGP-BPS2B batteries power capacity in the group, but also pay particular attention to the quality of batteries.
