Rechargeable battery knowledge

Why does the battery heat up during charging and discharging?
During the charging and discharging process, intense chemical reactions occur inside the battery, and most of these chemical reactions are converted into electrical energy, but a considerable part is also converted into heat energy release.
However, some batteries heat to a very serious degree, and even the outer packaging will break, these situations are mainly after long-term use of the battery or battery properties are not good, at this time should be replaced with a new battery.
 
How to care for battery products?
Do not place in high temperature and high humidity, because the battery and charger are electronic products, high temperature and high humidity will corrode electronic components.
Do not leave the charger plugged into the socket for long periods of time.
Do not overcharge the battery for a long time.
Remove the battery from the charger as soon as it is fully charged.
If the battery is not used for a long time, it should be stored after emptying. And every 3 months or so to remove the charge and discharge.
What happens when an exception occurs to the product?
The charger is smoking: Quickly unplug the charger and remove the battery. The charger smoke is generally caused by the mains voltage is too high and the transformer is burned out.
The battery is hot (the outer package will crack in severe cases) : Remove the battery quickly and cover it with a hard box for 1 hour to prevent possible danger. Battery hot is generally caused by short circuit battery or battery internal abnormal, at this time should check the charger circuit is normal, and detect the battery voltage (battery heating is normal when charging)
Battery leakage: Remove the battery quickly and cover it with a hard box for about 1 hour to prevent possible danger, then wipe the charger clean. The battery can't be used again after it leaks.
Unable to charge: Check the charger and battery. At this time, the product should be sent to the supplier's after-sales service office for processing, and the charger and battery should not be disassembled privately.
 
Why can't old and new batteries be mixed?
The performance of the old battery is much worse than the new battery, when mixed, the new battery will first supply power to the old battery, and the balance between the two will be reached before the electrical power supply. In addition, the old battery will generally be discharged before the new battery, and even if the new battery is charged, it can not supply power to the electrical appliance. Therefore, both batteries will not achieve the best results when mixed.
