How long does it take to charge a lithium battery for the first time?

Q: nowadays, not only cell phones or other devices generally use lithium battery. If I want to activate the lithium battery, how long do I need to charge for the first time?

A: the maintenance of lithium-ion batteries has been online dispute many a problem. There are some rechargeable batteries that need similar to "activate". This is earlier nickel cadmium rechargeable battery and nickel metal hydride rechargeable batteries. These cells produce a phenomenon known as the "memory effect", in the condition of incomplete discharge of charge, easy to make a battery overcharge, after a long time can lead to hyperplasia of crystal plate electrode, blocking the contact with the plate electrode, electrolyte battery voltage drop, let users having the feeling that the battery soon ran out.[1] therefore, for the two batteries on a regular basis, not every time completely discharge the battery before charging it that can reduce the causes of voltage drop phenomenon.

Now, however, we use mobile phone and laptop batteries, mostly lithium ion batteries(Li - ion battery).Lithium ion battery although figure is small, can save energy, so more and more widely used. Lithium ion battery when start to use does not need to be activated by the depth of the charge and discharge, because the initialization of the battery and testing process has been completed in batteries. Lithium-ion batteries also does not have the so-called "memory effect", can charge at any time.[2] suggest that regular lithium-ion batteries for a full charge and discharge, merely for calibration notebook computer and some high-end smartphones power detection device, not because of battery what's good about themselves.[3] to the ordinary mobile phone, digital camera, the segmented display battery power equipment, probably is completely don't need to fully charge and discharge on a regular basis.

What? Some mobile phone also has so to write on the manual? Do you want to know, cell phone batteries are generally not produced in the production of mobile phone manufacturers, the writing on the manual may be to remind the users to test the battery if you have any questions. In addition, because of the nickel cadmium and nickel metal hydride batteries do need activation, and this manual writing can also be caused by copying template.
