This laptop battery of non-original but the poor quality of the OEM batteries battery.

Such poor use of OEM laptop batteries are down from the old battery Satellite A60-662 to replace batteries or very poor quality batteries. That customers how difference?
The general performance of the battery market prices are quite low, and the insurance business is generally three to six months so that even Paul did not Paul is also possible. The whole time for a relatively short warranty. Because such batteries customers for some time, capacity will be quickly reduced standby time will be shorter and shorter. It is estimated that the standby time of 30 minutes only to win the next time, you will have to replace the new battery has.
Lithium-ion battery cathode material of lithium active compounds are usually composed of negative electrode is a special molecular structure of carbon. Common cathode material mainly composed of licoo2, charging, added to the battery positive pole of the electric potential to force the release of compounds, lithium ion, embedded negative elements arranged in lamellar structure of Satellite 1900 the carbon. Discharge, lithium-ion from the lamellar structure of carbon precipitation and re-cathode combination of compounds. Lithium-ion movement generated a current.
Lithium-ion battery capacity after repeated charge-discharge will decline, its causes are complex and diverse. Is mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ion on the hole to accommodate the structure will gradually collapse, plug; from the chemical point of view, is the active anode material is passive, there's the other side to form a stable compounds. Physics will appear on the cathode material gradually falling off, etc., in short, can ultimately reduce the battery charging and discharging process of the free movement of the number of lithium-ion.
Therefore, lithium-ion battery scrap battery Tecra 9100 factory to the final date, the performance of its capacity is to use a little time.

2. Battery factory manufactured laptop batteries to the user's hands for too long, short is 1 month or as long as a year.
Lithium-ion batteries have a very bad feature is that lithium-ion battery aging (or aging, foreigners known as aging), is a lithium-ion battery in storage for some time, even without the use of recycled will be a permanent part of its capacity loss, because the lithium-ion battery anode and cathode material from a factory has already begun its failure in history. Different saturation temperature and battery charge status, the consequences of its timeliness difference, the following is a test data from the network in order to The percentage of capacity Tecra 9000 listed in:
Storage temperature - 40% state of charge ------- 100% state of charge
0 degrees ------- 98% (one year later )----- 94% (one year later)
25 degrees ------ 96% (one year later )----- 80% (one year later)
40 degrees ------ 85% (one year later )----- 65% (one year later)
60 degrees ------ 75% (a year later )----- 60% (3 months later)
So, can there be manufacturer's suggested initial use of the notebook computer battery is best for 3 to 5 times full charge-discharge process in order to eliminate electrode materials passivation, to reach maximum capacity.
If it intends to replace notebook batteries friends you had better look Tecra 8100 at the date of manufacture of the battery!
