Great Tips To Laptop Battery Memory Effect
Although there is little lithium-ion battery memory effect of nickel-cadmium batteries
, memory effect is the principle of crystallization, in the lithium battery is almost not produce this reaction. However, lithium-ion battery capacity after repeated charge-discharge will continue to decline, its causes are complex and diverse. Mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ion
DELL XV90H Battery on the hole to accommodate the structure will gradually collapse, clogging; from the chemical point of view, is the passive activity of positive and negative material, there's the other side to form a stable compounds. Cathode material physics will appear gradually falling off, etc., in short, can ultimately reduce the battery charging and discharging process of free movement of lithium-ion number.
Over-charging and over-discharge, lithium-ion batteries will cause permanent damage to the positive and negative, from the molecular level, can be intuitively understood, excessive discharge of carbon anode will lead to excessive release of lithium ions and makes it appear lamellar structure collapsed, over- Rechargeable lithium-ion will too hard to go into negative carbon structure, and makes some lithium-ion can no longer be released. This is also why the lithium-ion batteries are usually equipped with charge and discharge control circuit of the reasons.
Second, the argument 2: external power supply is disconnecting the battery?
Point 1: Use an external power supply when the battery removed.
Point 2: Use an external power supply without removing the battery.
Survey Results: Most students in the use of an external power source, have the battery removed, only a few use an external power supply when the battery is placed above, this handful of students are used by several international famous brands
TOSHIBA Dynabook R631 Battery .
Proposed method: in fact the battery is removed, the conflict focused on the use of external power supply when the battery is charged to the issue. You know, the battery charge and discharge is directly related to life, the general lithium battery charge and discharge times set is fixed, the charge number only 400-600 times, specially modified products, but 800 times, each time the battery to charge a step forward to retirement. The first view is simply afraid to use power, the battery will be charged on the above, not only increase the number of charge cycles, and could lead to overcharging. The second view is that a fully charged battery on the computer, in the use of an external power supply will not be charged. In fact, both sides have their right side, but also the wrong place. It is only the views expressed by individuals, is not very comprehensive survey by the author, and now many notebook manufacturers are taking into account the vulnerability of the battery, and
HP 2000 Battery products added protection technology, and thus the corresponding different brand laptop batteries Charging protection technology is different, like some big companies do very well in this area, such as: IBM, HP, Toshiba, Compaq and so on. Which is considered the most thoughtful IBM, IBM laptop battery discharge condition can be detected; ThinkPad notebook battery only less than 95% of the time will automatically be charged. This can play a very good protective effect on the battery, and now many other manufacturers have followed suit. Therefore, the battery likes this, when you do not need to use the pull down, because only when the power is lower than 95% of the time it will be charged.
Notebook battery is the consumables, batteries Once opened use, will begin the process of aging. With the aging rate of the chemical characteristics of the battery varies. Aging rate is also used with the usual methods. If the frequent charge and discharge the battery, it will accelerate the aging batteries. Battery over a period of time, power will gradually shorten the time until it can not be used. Therefore, the shortening of the battery is a normal situation. Although usually you'll mostly use an external power supply, if not using
ACER Aspire 4733ZG Battery , but in reality, the battery's aging process over time, has been engaged in, use less battery can only delay the process, but can not make it stop:
Factors that affect battery life
Battery charge / discharge times
Ambient temperature (recommended temperature below 30 using computers)
Battery storage temperature
Shock suffered by the size of the battery
