　　How to charge 18650 battery 3.7v 1800mah when using it for the first time

　　If you want to extend the effective use time of your mobile phone battery, in addition to ensuring the quality of the charger, correct charging techniques are also essential, because poor quality chargers or wrong charging methods will affect the battery use time and cycle life. , here are some tips on charging mobile phone batteries, I hope it will be helpful to everyone:

　　1. Before the battery leaves the factory, the manufacturer has activated it and precharged it, so the battery has residual power. Some friends said that the battery is charged according to the adjustment period, but the standby is still seriously insufficient. Assuming that the battery is indeed a genuine battery, this In this case, the adjustment period should be extended and then fully charged and discharged 3 to 5 times.

　　2. If the newly purchased mobile phone battery is lithium-ion, the first 3 to 5 charges are generally called the adjustment period, and should be charged for more than 14 hours to ensure full activation of lithium-ion activity. Lithium-ion batteries have no memory effect, but have strong inertia. They should be fully activated to ensure optimal performance in future use.

　　3. Some automated intelligent fast chargers only indicate that the battery is 90% full when the indicator light changes. At this time, the charger will automatically change to slow charging to fully charge the battery. It is best to use the battery after it is fully charged, otherwise the use time will be shortened.

　　4. Lithium batteries do not need to be specially discharged before charging. Improper discharge will damage the battery. When charging, try to charge slowly and reduce fast charging. The time should not exceed 24 hours. Only after the battery has undergone three to five complete charge and discharge cycles will all the chemical substances inside it be "activated" to achieve optimal use.

　　5. Please use the charger from the original manufacturer or a reputable brand. For lithium batteries, use a special charger for lithium batteries and follow the instructions. Otherwise, the battery will be damaged or even dangerous.

　　6. Many people often leave their mobile phones on while charging. In fact, this can easily damage the life of the mobile phone, because during the charging process, the circuit board of the mobile phone will heat up. At this time, if there is an outside call, it may occur. Instantaneous backflow of current can cause damage to the internal parts of the phone.
