Charger operation method

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

Fast charge and slow charge

For example, the capacity of one AA 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, but combined with other charging methods.

When the charging current is between 0.1C-0.2C, it is called slow charging. Charging current greater than 0.2C, 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 the fast charge and slow charge converted according to 1C are also a relative value, just as the 200mAH charging current is a slow charge for a 1200mAH battery, and a fast charge for a 700mAH battery.
