Battery charger era in progress, technology in the development, now the 21st century, it can be said that the heat of electronic products reached a peak, and now people almost a smart phone, let alone some of the other mini fans, electronic watches , Toy sports car and so on. Since it is electronic products, then ultimately, to charge, and now almost all of the mobile phone can be used to charge usb, but that is actually white to the battery charge. So the question is coming, will you really charge it?
     Now most of the words are lithium batteries, some people say that because the number of charge and discharge is limited, so the phone battery should be used as much as possible to recharge the battery. However, this statement is clearly wrong!      Under normal circumstances, you should have the reserve in accordance with the remaining battery charge and then charge the principle of charging, but definitely not used to shut down and then recharge, because the lithium battery charging process, the voltage will be higher and higher, when filled When the voltage is the highest, the same power is the lowest voltage when it is the lowest, so we can conclude that both electricity or charging should leave some gaps, since it will not let it not let it use Finished, this is the most conducive to the battery work.
