If you are using a Vivo mobile phone, it uses a lithium polymer battery, which can be used once fully charged. There is no need to charge continuously for 12 hours or 24 hours. The normal charging time of the device is 3 hours.
Occasional long-term charging will not affect the battery; Long-term frequent charging will accelerate the number of battery cycles, thereby shortening battery life. When the device is fully charged, it should be turned off. time.
You can refer to the following methods to maintain the battery:
1. Do not wait until the battery is exhausted before charging it. Excessive discharge will have some impact on the battery. . In severe cases, this may cause equipment failure. If it cannot be turned on normally, try to charge it in time when the battery is too low;
2. p data cablefor loading. Non-original chargers may have various problems and damage the battery, thereby reducing battery life;
3. When loading, try not to play while loading. , it is easy to increase the heat, easily consume the battery and shorten the battery life;
4. Charging When finished, please disconnect the power supply in time to avoid charging for a long time;
5. Avoid using the device in a high temperature environment.
Warm reminder: Batteries are consumables. As the number of charges increases, the actual battery capacity decreases.
The activation method for lithium batteries left unused for too long is as follows:
1 Prepare the 18650. lithium battery to be activated. A normal lithium battery requires voltagegreater than 4.0 V.
2. Prepare a section of wire. Peel off a small section of the outer skin on both ends of the wire to expose the copper wire inside, which can directly conduct electricity.
3. Connect the above two batteries (one is a normally charged battery and the other is a non-rechargeable battery) in parallel with wires - connect them in parallel for about 4 or 5 seconds. Determined according to the actual situation. Then separate and measure the voltage of the battery that could not be charged before. It will usually be above 3.0 volts.
At this time, the unused non-rechargeable lithium battery can be charged. Note that you may see small sparks when two lithium batteries are connected in parallel. Sometimes the battery temperature rises, but it is not hot. It's normal.
If you try the above method several times andthe old lithium battery still has no voltage, you can give up.
Note:
Self-discharge of lithium batteries will cause serious power loss, and low voltage at this time will cause excessive charging current, which can easily cause explosion .
Nowadays, many chargers have a charge protection function, which will automatically detect the battery voltage and automatically stop charging when the voltage is too low to avoid explosion.
In addition, it can also be activated with a special charger. Most lithium batteries can be activated with a universal charger.
Before activating, first use a multimeter to measure the battery voltage, then use an adjustable DC power supply slightly higher than the battery voltage (0.5V-1V). ) while charging, when the battery voltage increases enough to be chacharged by the charger, then use the charger to charge.
