Dell, HP, Lenovo Acer laptop battery maintenance methods

Lithium laptop batteries are generally able to charge and discharge of 300-500 times. Best part of the discharge of lithium, rather than fully discharged, and to try to avoid frequent
Fully discharge. Once the battery off the production line, the clock began to move. Whether you use, the lithium battery life of only two to
Three years. The decline in battery capacity due to oxidation caused by the increased internal resistance (which is the main reason for the decline in battery capacity). Finally, the
Cell resistance will reach a certain point, although this time the KODAK Easyshare M873 Zoom Charger battery is fully charged, the battery can not release the stored electricity.
The lithium battery aging rate is determined by the temperature and charge state. The following table shows the reduction of battery capacity in the two parameters.
Temperature charge 40% (recommended)
Charging 100%
0 ° C, 98% a year
94% after one year
25 ° C, 96% a year
80% after one year
40 ° C
85% after one year
65% after one year
60 ° C 75%
A year later
60% after three months
The figure shows, the high charge state and the increase in temperature accelerated the decline in Sony Cyber-Shot Dsc-t33 Battery capacity.
If possible, try to charge the battery to 40% placed in a cool place. The protection of the battery itself so you can make in the long retention period
Circuit operation. If after the battery is fully charged at high temperatures, so the battery will cause great damage. (When we use the fixed electrical
Source when the battery is fully charged state, the temperature is generally between 25-30 ° C, which would harm the Olympus Sp-700 Battery, the cause of its capacity
Down).
Although the use of laptop computers, high-temperature battery will bring damage. But removing the battery, the use of fixed power supply there will still be some risk of electric
The pool package dust and moisture will cause damage to the battery, so manufacturers are generally warned not to remove the battery. Then you will be a period of
Period need to replace the battery, this is the case, the manufacturer is very happy.
Some of the battery due to excessive low discharge will be scrapped. If you put the battery internal safety circuit will start below 2.5 volts per cell,
Battery a bit difficult to use. However, if the battery is down to 1.5 volts per cell, and to maintain the state for some time, for safety
Reasons, do not charge the battery. To avoid the occurrence of such cases, do not store the Canon Powershot s100 Battery fully discharged. Should be in the store before charging a
More power and fully charged before use.
All in all,
(1) to avoid complete discharge, often charging a lithium battery. Repeated random charging will not damage the battery.
(2) lithium battery in a cool place, rather than frozen. Avoid placing them in a hot car. If stored for long periods, the battery charge to 40%
After placing.
3.
If you most of the time is to use a fixed power, remove the battery in a cool place.
Avoid purchasing spare lithium Olympus Sp-700 Battery for storage. Nanjing Eagle-dimensional notebook Maintenance Department, Nanjing Eagle-dimensional notebook repair center by more than
