How to identify non-original laptop battery is not the OEM battery but the poor battery

This laptop battery but poor non-original battery OEM battery.
The poor quality OEM laptop batteries are used in toshiba satellite a75 battery replacement down from the old batteries or batteries of very poor quality. That customers how the difference?
The general performance of the battery market prices are quite low, and insurance business is generally three to six months so that not even Paul Paul is also possible. All in all a relatively short time warranty. Because the battery customers for some time, capacity will be quickly reduced, the standby time will become shorter. It is estimated that the standby time of 30 minutes only to win next time, you will have to replace the battery.
Lithium-ion toshiba satellite a80 battery cathode material of lithium in the active compounds are usually composed of the negative 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 of the compound to force the release of lithium ions, embedded negative elements were arranged in the lamellar structure of the carbon. Discharge, lithium-ion from the lamellar structure of the carbon precipitation and re-cathode combination of compounds. Lithium-ion movement have a current.
Lithium-ion toshiba satellite l25 battery capacity after repeated charge-discharge will 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 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.
Therefore, lithium-ion battery scrap battery factory to the final date, the performance of its capacity is to use a little time.
2. Battery factory to the user’s laptop battery factory hands too long, short is 1 month, long as a year.
Characteristics of lithium-ion batteries have a very bad, that is, the limitation of lithium-ion battery (or aging, foreigners as aging), is a lithium-ion battery in storage for some time, even without recycling, will be a permanent part of their capacity loss, because the lithium-ion toshiba satellite l350 battery anode material from the factory has already begun its failure history. different temperature and battery fully charged state, the consequences of their different time, the following is a test data from the network to listed as a percentage of capacity:
Storage temperature – 40% ——- 100% state of charge state of charge
0 degrees ——- 98% (94% )—– year later (a year later)
25 degrees —— 96% (80% )—– year later (a year later)
40 degrees —— 85% (65% )—– year later (a year later)
60 —— 75% (60% )—– year later (3 months later)
Therefore, manufacturers recommend the initial use will have a toshiba satellite p20 battery is best for 3 to 5 times full charge-discharge process, in order to eliminate electrode materials passivation, to reach maximum capacity.
If the intended replacement laptop battery factory friend you had better look at the date of the battery!
