Charging is an important step when using rechargeable batteries. Proper and reasonable charging is good for extending battery life, and improper charging will have a great impact on battery life. Lithium batteries are basically individually packaged according to each product, which is not universal. Therefore, each product also provides its own charging equipment, which is not universal. Just use it in accordance with the respective instructions.

Fast charge and slow charge

For example, the capacity of one Ni-MH battery is 1200mAH, while the other is 1600mAH. The capacity of a battery is called 1C. When charging, when the charging current is less than 0.1C, it is called trickle charging. Trickle charging can fully charge the battery without harming battery life, but the time it takes to use trickle charging is too long, so it is rarely used alone, and it is charged with other
Use in combination.

When the charging current is between 0.1C and 0.2C, it is called slow charging. Charging current is greater than 0.2C, and less than 0.8C is fast charging. When the charging current is greater than 0.8C, it is called ultra-high-speed charging.

However, 1C is a logical concept rather than an absolute value, so fast charging and slow charging based on 1C conversion is also a relative value, just as 200mAH charging current is slow charging for a 1200mAH battery and fast charging for a 700mAH battery.
