How do I buy a new cell phone battery to fully activate the battery?
However, the battery used on the phone now, mostly lithium-ion battery. Lithium-ion batteries do not need to be activated by deep charge and discharge when they are started, because the battery initialization and testing process has been completed when the battery is manufactured. Lithium-ion batteries do not have the so-called "memory effect", you can always charge.
Should try to reduce the battery full state of the time. Do not unplug the power after charging, make the battery has been fully charged state, although it will not explode, but will speed up the loss of battery capacity.
Frequent shallow charge and discharge than the depth of charge and discharge to help extend the battery life, do not think that the number of times the battery will damage the battery, this argument does not apply to lithium-ion battery. So, the good habit is to have the opportunity to plug in the charge, charge almost pull out - a small amount of meals, but do not eat too full.
Earlier, there were some rechargeable batteries that needed similar "activation" work. This is the early use of nickel-cadmium rechargeable batteries and nickel-metal hydride rechargeable batteries. These batteries will produce a phenomenon known as the "memory effect" in the state of incomplete discharge, easy to make the battery overcharge, a long time will lead to the electrode plate on the proliferation of crystals, blocking the electrolyte and the electrode plate contact , Resulting in the battery voltage drop, so that users will soon run out of the battery feeling. For both batteries, it is possible to reduce the voltage drop caused by the above-mentioned causes on a regular basis (not every time) after the battery is fully discharged and then charged.
