Common sense about batteries
    Normal charging
Different batteries have their own characteristics, and users must charge them according to the method indicated in the manufacturer's manual. In the standby state, the phone also consumes the battery. If fast charging is required, it is advisable to turn off the phone or remove the battery for charging.

    fast charging
Some automated smart fast chargers only indicate that they are 90% full when the indicator signal changes, and the charger will automatically switch to slow charging to fully charge the battery. It is best for users to fully charge the battery before use, otherwise it will shorten the use time.

    Memory effect
If the battery is a nickel-cadmium battery, if it is not fully charged or discharged for a long time, it will leave traces in the battery and reduce the battery capacity. This phenomenon is called the battery memory effect.

     Erase memory
The method is to completely discharge the battery and then recharge it. Discharge can use a discharger or a charger with discharge function, or use the standby mode of the mobile phone. If you want to speed up the discharge, you can turn on the lights of the display and the phone buttons. To ensure that the battery can be fully charged again, you should control the time according to the instructions of the manual, and repeat the charge and discharge two to three times.

    Battery storage
Lithium batteries can be stored in a clean, dry and ventilated room with an ambient temperature of -5°C-35°C and a relative humidity of not more than 75%. Avoid contact with corrosive substances and keep away from fire and heat sources. The battery power remains 30% to 50% of the nominal capacity. It is recommended to charge the stored battery every 6 months.
