How to operate the charger

Charging is an important step in using rechargeable batteries. Proper and reasonable charging is beneficial for extending battery life, while improper charging can have a significant impact on battery life. Lithium batteries are generally packaged separately for each product and are not compatible with each other. Therefore, each product also provides its own charging device, which is not compatible with each other. When using them, simply follow their respective instructions.

Fast and slow charging

For example, the capacitance of a 5th nickel hydrogen battery is 1200mAH, while the capacitance of another battery is 1600mAH. The capacitance of a battery is called 1C. When the charging current is less than 0.1C during charging, it is called trickle charging. Trickle charging can fully charge the battery without damaging its lifespan, but the time it takes to use trickle charging is too long, so it is rarely used alone, but in combination with other charging methods.

When the charging current is between 0.1C-0.2C, it is called slow charging. A charging current greater than 0.2C and less than 0.8C indicates 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 conversion of fast and slow charging based on 1C is also a relative value, just like a 200mAH charging current is slow charging for a 1200mAH battery and fast charging for a 700mAH battery.
