How to charge a new mobile phone battery?

How to charge a new mobile phone battery 1. The mobile phone battery is composed of a battery, a maintenance circuit and a casing. At present, mobile phone batteries are lithium batteries (often referred to as lithium batteries in non-standard occasions), and the cathode material is lithium cobalt oxide. Specifications discharge voltage 3.7v, charge cut-off voltage 4.2v, discharge cut-off voltage 2.75v. The power unit is Wh (watt hour). Since the discharge voltage of the mobile phone battery specification is 3.7v, mAh (milliampere hour) can also be used instead. The conversion link between these two units on the mobile phone battery is: Watt hour u003d Ampere hour × 3.7.2. Overcharge, over discharge and short circuit will seriously damage the performance of the battery and may cause risks in use. In order to achieve this goal, a thin maintenance circuit board is usually built into the battery of a mobile phone to prevent these risks. 3. The charger is divided into direct charging and blocking charging. DC converts 220 AC power to 5V DC, input it to the mobile phone and lowers the voltage through the mobile phone's charging circuit for battery use. Generally, the mobile phone will be delivered to your door when you buy it. Socket charging is directly connected to the battery, which converts the electrical energy into the voltage required by the battery. 4. If you use a cradle charger, please try to choose genuine or high-quality products. If the charging circuit of the base charger is of poor quality, there will be a charging risk. 5. Lithium batteries have no recall effect, but they are inert, and may be passivated if they are not used for a long time. The best performance can be restored after several times of charging. 6. Do not discharge the lithium battery specially before charging. Some fast chargers will only display 90% excess power when the indicator light changes, while the charger will actively change the excess power at a slower speed. But generally speaking, as long as you look full, you can take off. 7. In order not to damage the battery life, it is best to charge slowly; this time should not be too long. 8. Mobile phone batteries have self-discharge, because over-discharge will damage the battery. If the mobile phone battery is not used for a long time, ensure that the battery has a certain amount of power. 9. Although our mobile phone is in the network coverage area, our mobile phone has been unable to answer and call when the mobile phone is turned off. At this time, we can use the transfer function of the mobile phone to transfer the mobile phone to a nearby fixed phone. In order to prevent the loss of the call, this method is not in the network coverage area or the signal is weak and temporarily unable to connect. 10. Don't expose the battery to high or low temperature, like three volts, don't put the phone in the car, expose it in cool weather; or go to an air-conditioned room and blow it directly in an air-conditioned place. It is normal for the battery to generate heat when charging, but this does not make it immune to high temperatures. To prevent this, it is best to charge the phone at room temperature and do not cover the phone with anything. 11. The charging time is not as long as possible. Regarding the remaining batteries that are not maintained, the overflow should be stopped after charging. If it is not used for a long time, the battery and mobile phone should be used separately. The first time on the twelfth is to use the newly purchased battery for 12 hours, but it is best to perform a thorough charging process of 3 to 5 hours. The complete charge is a normal charge to 100%. When the phone is fully discharged, it is a reminder that the phone uses low power. After the battery is filled with electrolyte before they go out, Rabin, charge and discharge, capacity, during the process, the battery is active, but this will be less than a month later and more than a year to go to the user's hands, because the battery self-discharges the battery material The effect of the current passivation, after being fully charged and discharged at this moment, can allow the cell to activate.
