The use of cell phone batteries
Jul 25, 2017

One: charge after the battery is exhausted 

Affected by the use of nickel-metal hydride batteries, many people still prefer to recharge their batteries completely. In the case of lithium batteries, this does not help to avoid the memory effect, and the lithium element activity is insufficient when the battery is used up, which can affect the battery capacity in the long run. 

2: cell phone battery should not be full of (or empty) electricity for a long time 

Many people have multiple phones or batteries, some of which can be put away for long periods of time, and many use two extreme practices -- full of electricity or free electricity. The correct way to do that is to charge 40 to 60 percent of your phone's battery life and store it in a cool, dry place. 

3: the first charge will take more than 12 hours 

More than 2013 mobile phone use lithium battery, and once the nickel metal hydride batteries, lithium batteries have no memory effect (the correct memory effect is very weak, there is no activation, long charge will cause some damage to the battery. So how much is the first time to charge? This also depends on the capacity of the battery. Generally speaking, in 2 ~ 4 hours, the mobile phone shows that it can take half an hour after charging. 

4: overcharging can cause battery explosions 

The lithium battery usually has safety protection circuit and various safety devices to ensure the automatic cutting of the battery when overcharging and short circuit; High pressure inside the battery can also trigger the venting device to decompress. The high temperature of the battery triggers the thermal protection device to stop the battery's electrochemical reaction. Therefore, unless there is a quality problem, the battery will not explode because of long time plugged in.
