The main performance indicators of rechargeable batteries

The main performance indicators of rechargeable batteries

Safety performance of the battery failure is unacceptable. One of the greatest impact is the explosion and leakage. Explosion and leakage of the battery occurred mainly with the internal pressure, the structure and process design (such as a safety valve failure, there is no lithium-ion battery protection circuit, etc.) and should be prohibited by incorrect operation (such as the battery into the fire) the. Refers to a certain discharge conditions, the apple laptop battery can be released from the total power consumption. In accordance with the IEC standard and GB, nickel cadmium and nickel metal hydride batteries in the 20 ± 5 ° C conditions, the 0.1C charge for 16 hours after discharge 0.2C to 1.0V out of electricity when the battery's rated capacity, expressed in C; lithium-ion batteries at room temperature, constant current (1C), constant voltage (4.2V) under the conditions of 3 hours after charging to discharge 0.2C to 2.75V when the battery out of power for the rated capacity. The unit of battery capacity mAh and Ah (1Ah = 1000mAh). To AA 2300mAh Ni-MH rechargeable apple a1175 battery as an example, that the battery in order to 230mA (0.1C) charge 16 hours to 460mA (0.2C) discharge to 1.0V, the total discharge time of 5 hours, the release of the electricity for the 2300mAh. Correspondingly, if the discharge current of 230mA, the discharge time is about 10 hours a day. Refers to the internal resistance of battery current flow when the battery internal resistance. Small internal resistance of rechargeable batteries, the need for specialized equipment used can be measured more accurate results. General knowledge of the battery charge state resistance is resistance, meaning that the battery internal resistance when fully charged (which corresponds to the internal resistance of the discharge state that after the battery fully discharge resistance. In general, the discharge state resistance charge-state resistance than the large, and not very stable). The greater the internal resistance of batteries, the battery itself consumes more energy, more efficient use of battery low. A lot of resistance when the battery charge is very much heat, so that the battery temperature rises rapidly. On the impact of batteries and chargers are great. With the increase in the number of battery life, due to the consumption of electrolyte and battery internal chemical activity in the reduction of the internal resistance of the apple a1185 battery will be increased to varying degrees. The poorer the quality of the faster rise in the battery. Cycle life batteries that can be experienced in the number of repeated charge-discharge. Battery life and capacity into the reverse relationship, in general Ni-MH battery cycle life of more than 500. High-capacity apple m8403 battery life is shorter, but more than 200. Cycle life and charge also closely related to the release conditions, in general the greater the charge current (faster charging), the shorter the cycle life. Maintain the ability to charge that is often talked about self-discharge, is the open state, the battery storage of electricity under certain environmental conditions to maintain the ability. Mainly by self-discharge battery materials, manufacturing process, storage conditions, and many other factors. Usually the higher the temperature, the greater the self-discharge rate. Rechargeable battery to some extent the self-discharge is a normal phenomenon. For example in nickel-hydrogen Apple PowerBook G3 M7572 Battery, IEC standards, after fully charged battery at a temperature of 20 ± 5 ° C, humidity of 65 ± 20% conditions, the open-shelved within 28 days, 0.2C discharge time shall be not less than three hours (that is, the remaining power greater than 60%). Lithium-ion batteries and dry cell battery is much less self-discharge. That is, the capacity of large current discharge. Digital cameras, power tools, electric toys, such as electric appliances in particular need excellent large current discharge performance of a ,apple a1012 battery ,apple a1079 battery , apple a1078 battery , apple a1148 battery. High-current discharge performance of primary and battery-related materials and production process.

Notebook battery maintenance


Notebook from the birth of the day, the VGP-BPS5 battery on the controversy has never stopped, because the use of persistent notebook is a very important technical indicator, and battery capacity of the notebook's decision this important indicator. Because of technical reasons, the battery capacity will be affected by the use of the frequency-to-earth habits and the use of the storage environment and other factors to reduce or loss. In the end how can we maximize the use of the battery to play the effect of extending the battery life of it?
Many users of laptop batteries for use just to stay in the primary stage, how to protect the battery as well as the rational use of all batteries do not know. Whenever these big customers to complain about battery life is too short or long battery life is not at the same time is first of all carefully from the normal use of their own look for the reasons for this? Of course, these two problems caused by the vgp-bps5 battery does not rule out the reasons for their quality, but the vast majority of the current situation, improper use of man-made is a very common phenomenon.
Here are a few common errors in the future when the battery should pay attention to it! (Without all that for now the most commonly used lithium-ion battery)
For the first time the use of batteries, three times before the need to charge 12 hours? This is totally unnecessary. Because the laptop has improved power management circuits and charging management system, when the battery reached saturation, the control circuit will automatically switch to the open state, so even if the charge is a long time to no avail.
In order to prevent the memory effect, should it run out of electric charge it? Every time charge of vgp-bps5 battery discharge before it is not necessary, but also harmful, as they had proved the depth of discharge the battery life will reduce unnecessary, when the proposal to use about 10% of the battery can be recharged when the. When the battery, of course, there are still more than 30% of electricity when it would be better not to charge, because the memory effect is real.
Insert AC, the battery should be to win in order to prevent repeated charge and discharge it? I suggest that is: do not have to. You might get lithium-ion battery discharge natural to refute me, saying that if the natural discharge after the battery if there is access to power will be reduced by repeatedly charging and discharging of the battery life. I give you a "no" answer to the following reasons: 1. Notebooks now have the power control circuit design of the features: When the battery is 90% (as most of the HP models) or 95% of the charge will be, and to achieve this through the natural discharge capacity of 2 hours a week , I would say when the batteries do not have to idle for about a month to complete in order to maintain the battery charge and discharge capacity at this time you should be concerned about the battery should be about training the body and not be left idle after the re-charge; 2. Even if the battery "unfortunate" was once again charge, the loss will not be brought about by the long period of time than the battery consumption caused by the large decline in the number. 3. Your data than you or your VGP-BPS5 notebook batteries are much more valuable, not only power all of a sudden you have a notebook injury, is unable to restore the data it is too late to regret the.
Long-term need to preserve battery power is full of it? Read the following table on this clear: (percentage of saturation at the time of the initial value of the relative percentage) Storage temperature of 40% of the state-of-charge 100% state of charge 0 degrees 98% (after one year) 94% (after one year) 25 degrees 96% (after one year) 80% (after one year) 40 degrees 85% (after one year) 65% (after one year) 60 degrees 75% (after one year) 60% (3 months) It is clear that if the long-term preservation of the battery, as far as possible on the dry and low temperature environment so that the remaining battery power in about 40% of the ideal, of course, should be the best month to come up with a VGP-BPS5 battery that can ensure a good save battery , Also would not let the loss of full electricity and cell damage.
As far as possible in how to use the notebook to extend the use of time? 1. To reduce the brightness of the screen. However, large-screen LCD power consumption, reduce the brightness can be used to extend the time; 2. PowerPlay and open SpeedStep power-saving features, and so on. Now the notebook and display processor chips have a lower frequency and voltage to extend the use of the function of the time, open the corresponding options can significantly extend the battery life; 3. The use of hard disk drive and the deceleration of the software. If NERO DriveSpeed, PowerBooster software can reduce the drive, hard disk drives, such as speed, can effectively reduce the power consumption of vgp-bps5 notebook; 4. Make the best use of standby, sleep and other functions. When a longer period of time do not have a computer that allows notebook standby or hibernation, both to save power and extend the service life of the computer
