Battery is a "consumables," the degree of damage depends on the battery Laptop Battery when you use the battery for the correctness of the operation, the operation mode, operating frequency, the working environment temperature, storage time (for unused batteries), etc. Factor .
1. The battery charge and discharge frequency is directly related to battery life, in general the number of lithium battery charge and discharge of about only 400 ~ 600 times, improved product nothing but 800 times, each time the battery charge on the end to the use of a step forward. (When the power of 85% or less of the battery charge, will be recorded and to increase the number of times on a single charge.)
To this end, when the battery Apple M8244 Battery voltage is greater than the battery-management process set starting value 96% charge, and your current place in which there is 220V AC power, they should make full use of AC power to minimize the number of battery charging to extend the Battery life.
At this point the battery do not have to remove from the machine because it will not start more than 96% of the electricity to recharge the battery. But even so, if you are a long-term use AC power and rarely used the battery, it is recommended, or remove the battery from the machine to compare the good, because the long-running laptop heat generated when the battery will cause some damage. It should be noted that in such a case, once the AC-powered power outages, you have not saved data will support the absence of cell loss, this was a failure, the user must Apple M8511 Battery carefully weigh.
2. When the power is 3 ~ 5%, it should be timely to charge the battery, or battery self-discharge phenomenon will cause over-discharge and damage to the battery, charging the machine and may be shut down, suspend any other state, you can also charge while edge use.
Charging must be a full, otherwise it will damage the battery. This is based on reduced sufficient to avoid an increase with cycle number of charge cycles and shorten battery life; rather than due to "memory feature" issue, lithium batteries, unlike nickel-cadmium batteries and nickel-metal hydride batteries have "memory characteristics", lithium batteries do not have the "Memory characteristics. "
If charging machine at shutdown or hibernation, when the Apple A1012 Battery charge to 3 ~ 4 hours after the green power status indicators are no longer beating, the time has reached 100 percent capacity, it is timely removal of the AC power plug to prevent excess charge on the battery The damage the battery.
If charging machine was waiting, hang, or side with the state of charge while, then when the charge to 3 ~ 4 hours after the green power status indicators are no longer beating, the battery will automatically exit charge state.
Charging process will carry out a fast-charging, when the power status indicator light yellow (Chang-liang), filled to a certain a certain value into the thin trickle charge current is slow, when the power status indicator light flashes green the color becomes ; has been filled with 100%, after, it becomes green (Chang-liang) of the. Lithium battery charging process is the constant pressure Apple PowerBook G4 15inch Battery approach, and began charging voltage that will soon stabilize, while the current is getting smaller and smaller.
3. Power is not fully depleted before (ie electricity at 5 ~ 100%), not to recharge the battery, otherwise they will reduce the charge to increase with the cycle number of charge cycles and shorten battery life.
When the power is 5 ~ 95% battery should be used, so the use of AC power adapter will charge the battery (charging side by side state).
4. When the power is 96 ~ 100% or the battery removed from the machine can use the AC power adapter switched on, use the AC power adapter AC power adapter when you please put the DC output plug on the plug into the machine, Apple PowerBook G4 Battery and then AC power plug to plug it into 220V ~ socket; removed when the AC power adapter should be first, and then unplug the AC power plug from the machine, unplug the AC power adapter DC output plug. Otherwise, they might damage your equipment.
Using the AC power adapter, when the AC power plug to plug it into 220V ~ socket, while the power status indicator on the machine yet, gave the former (Note: During this period of about 5 seconds time), please press the power button to turn; shutdown or go to sleep, in addition to green power status indicator lights have been extinguished all the other things, make a timely manner from 220V ~ unplug the AC power outlet plug (not later than 5 seconds), AC power plug pulled out in about 5 seconds , the green power status indicator light turns off; otherwise the battery will overcharge and damage caused by the battery. Off state due to AC power adapter is still non-discharge state, the system's power management procedures and battery power management chips from inside the interface apple PowerBook G3 Battery circuit composed of about 5 seconds will be automatically transferred to the "off state of charge", recharge the battery. (If necessary, may from time to unplug from the machine on AC power adapter's DC output plug, this time the battery will discharge through the AC power adapter reverse.)
If the suspension of work in order to wait for the machine to enter, or suspend state, not from 220V ~ socket unplug the AC power plug; so when the machines still have the power to maintain. (Not recommended for a long time to make the machine enters a wait or suspend state, in order to care for your machine.)
5. IBM in ThinkPad notebook computers information technology indicators have highlighted the "battery" is the manufacturers are measured under conditions specific to the indicator used in our normal notebook can not be achieved under the conditions of the , for example: information technology-related indicators have highlighted the "battery" for 4 hours, we can only get the normal use of about 3.5 hours of battery power supply. If the difference Apple M7318 Battery is very far, and is still under warranty, dashing contact IBM.
Maintenance and storage of
1. If the battery is a long time (several months) do not, we should start the machine remove the saved backup. Recommended that each one and a half or so once the battery discharge and charge order to improve the status of your battery to increase battery capacity.
2. If the battery is not a long time, it should be power set to 30 ~ 50% in stocks, it is recommended to charge the battery about once a year, and its capacity is set to 30 ~ 50%, to prevent over-discharge and damage to the battery. The battery is set to 30 ~ 50% of the specific operation method: When the battery power is greater than 50%, it can turn power to 30 ~ 50%. If the power consumption of less than 30%, then the first boot power to 3%, then recharge to 100% and then turn to 30 ~ 50% power consumption can be.
3. Do not put the battery temperature and a cold environment, the battery performance will be temporarily reduced. Should be at standby mode to save battery Apple M8403 Battery life and storage of the state placed in places of lower temperature for the battery, the best temperature range is about 10 ~ 20 degrees Celsius.
Charging start value on adjustments
Charge starting value is set, click the system tray in the power plug icon (when you use the AC boot), or large white battery icon (when you use the battery at boot time) / select Improve Battery Health / modify the Start charging when below values.
Do not extend the charge cycle deliberately use substantially changed in battery Apple M9324 Battery management programs charge set start value; because when you charge a low start value set (for example, 80%), though with the battery using the AC power adapter "charge with the cycle" may take up to three or four months, but if the battery when in use is bound to have to deal with their re-activate, otherwise the battery status and capacity of poor. This is in fact increased the number of charge cycles and shorten battery life. Furthermore, the battery every month and a half or so in need of a discharge and charge order, which is located due to charge a low start value (for example, 80%) after extended charging cycles will be more obvious with the meaningless.
After the battery is fully charged due to the phenomenon of self-discharge capacity fell to 96% generally last for about 50 days, while the battery every month and a half or so just in need of a discharge and charge order, it is apparent, IBM for us since pre-charge start value of 96% is not unreasonable. However, with the aging batteries, the battery is fully charged after the phenomenon of self-discharge of electricity due to fall to 96% of the necessary time may Apple A1185 Battery be shortened, this time we have a need to charge slightly lower start value, so that the time just in one and a half months about.
If you often need to live in the office and equipment, between the "Two Cities" campaign to curb the office with the AC adapter power supply operation, while the device is battery-powered operation of the site, it is recommended you charge start value is set to 6%; This will reduce the charge to avoid the increased number of charge cycles with the cycles shortened battery life; and will not affect the care of the battery while the mobile edge notebook.
Please note that the issues discussed in the text is limited to IBM ThinkPad notebooks, other brands of machines this article for reference only, since different brand machines, its system of power management and control procedures, as well as battery battery management, monitoring programs are not the same Apple A1175 Battery with the rules .
