How to activate a new battery?

When talking about the use of new battery, we will usually see a view: "we buy a new battery will have more than 3% of the electricity, put the battery's remaining electricity is used up, until the shut down, then external power supply charge.In order to activate the battery, charging time must be more than 12 hours,and repeated three times to do . "



The review is correct or not ? In fact, the majority of cases, we have no trouble to activate a new battery. Now a lot of batteries has be actived completely at a time when the factory ,in order to avoid the natural wear and tear to damage the battery, notebook battery are with a little power. Should be activated battery protection circuit in the absence of circumstances, it can be a lithium battery protection circuit, this circuit is designed in order to avoid over-charging and discharging batteries,generally,when battery is full, the charging indicator goes out, the battery on the electric charge does not enter, If we continue to charge the battery,Will be useful?



According to the state of battery,you can see the battery is full or not. Teaching you another simple method that can be judged on the battery during the charging or not. When charging,battery's phenomenon will have fever, when the battery is full after an hour (power do not pull the plug), you try it again, whether the battery is hot or not? The results are certainly cold, because the discharging-status of battery is not heat.



Notebook manufacturers will be proposed that a new battery charger more than 10 hours,when a battery is factorying. Maybe this word give some users the first error point of views. The opinion of authoris should the notebook manufacturers are taking into account some new users ,beacause new users can't completely grasp the skills,and allow them to charge 10 hours, so this should be the business of expediency.

The working principle of lithium batteries

Lithium-ion battery working principle refers to the principle of charging and discharging. When charging batteries, the batteries have a lithium-ion cathode generation, after generation of lithium-ion electrolyte to the anode exercise. As the carbon anode was layered structure, it has a lot of microporous, the arrival of Li-ion on the anode embedded in the porous carbon layer, the embedded lithium-ion more the higher the charge capacity.


Lenovo/ibm thinkpad T40 batttery is a high quality and hi-capacity lithium ion battery,a best replacement for original thinkpad T40,T41,R52 and so on.


By the same token, when the battery discharge (ie, we use the process of the battery), embedded in the carbon anode in lithium-ion layer extrusion, and sports back to cathode. Back to cathode of lithium-ion more higher discharge capacity. What we normally refer to the battery capacity is the discharge capacity.


It is easy to see, in the lithium-ion battery charge and discharge process, lithium-ion at the anode from the cathode → Sports → cathode status. If we put lithium-ion battery Saying for a rocking chair, rocking chair at the two ends of the bipolar battery, and lithium-ion as the outstanding athlete, at running back and forth at the two ends of a rocking chair. Therefore, the experts gave a lithium-ion battery lovely name rocking chair batteries.
