What is the meaning of built-in lithium battery? How to charge the built-in lithium battery? Speaking of cell phones with built-in batteries have to mention IPhone, although there are also phones with built-in batteries before, but most people's memories or Nokia can remove the battery of the phone, remove the battery can be replaced at will, can be configured with multiple batteries, etc.. So what is the built-in battery? How to charge the built-in lithium battery? Let's discuss it below!
What is the meaning of built-in lithium battery?
The built-in battery is also known as the non-removable battery, which is connected to the main board of the phone through the cable. Now many cell phones use built-in battery because the built-in battery can achieve an integrated body to make the phone look more compact, and can avoid the phone received in the process of using the impact damage, resulting in poor battery contact problems.
In the UPS power supply, the biggest difference between built-in and external is that one of the batteries is inside the UPS, one outside the UPS. The built-in battery is integrated with the UPS, due to the small size of the UPS is generally installed in the battery capacity is generally very small, rarely expand the battery pack. External batteries are not integrated with the UPS has a separate battery cabinet, the general use of external battery UPS power are relatively large, its battery pack according to the power supply time to increase the battery capacity or increase the number of battery packs to extend the purpose of power supply.
How to charge the built-in lithium battery?
1, theoretically you can make your own charger, the battery interface is too small to be connected to the universal charging circuit can be used, or find a used phone to use the power part, and universal charging circuit can be connected together, because this operation requires a certain electrical engineering basis and a certain degree of danger, so be careful.
2, the best charging method is to use the computer charging, you can find the most suitable current according to the performance of the built-in lithium battery; or buy the most compatible charger, the built-in lithium battery has a specification written on the back of the "DC input" type of words, the charger also has specifications on the back, and then use the data cable to connect the charger and the built-in lithium battery Plug up the charger and the built-in lithium battery can be charged, the general battery for the first time to overcharge 8-12h to help activate the lithium ion so that the battery performance better.
3, built-in lithium battery 20% or less should be charged, built-in lithium battery in the low power when the lithium ion activity will be reduced, which will reduce the battery life, so both storage and normal use should keep the power at more than 20 percent, long-term storage should be fully charged and then stored.
4, lithium battery since the day of appearance there is no memory effect, built-in lithium battery activity will slowly decay with time and the number of charge and discharge, charge and discharge 1000 times is the industry's universal standard, the worst production process to reach 1000 times completely charged and discharged, it is charged from 10 percent below to full. Once the battery is full the phone's charging circuit will be closed, even if plugged into the power supply for a year will not be charged in again, this is the charging circuit design.
Most cell phones today are built with built-in batteries, removable batteries do not fit the trend of the times, because the phone has now become a consumable often played, once the phone only to call, look at text messages will come out to see, and now the Internet, play games, read novels, and even office are on the phone, and removable batteries if often disassembled will inevitably lead to a larger gap in the phone, a variety of ash, a variety of paint affects the aesthetic.
