How long do different types of rechargeable batteries need to be recharged?

How long do different types of rechargeable batteries need to be recharged? If the charging time is not long enough, will it affect the battery's service time? If the charging time is too long, will it cause a fire?

How long the battery will be filled depends on the nominal capacity of your battery. The larger the capacity, the longer the charging time required. Second, it depends on how many batteries you charge at the same time. The charging time of two and four sections is different. The charging time of two sections is twice as fast as that of four sections. The third is to see the current output of your charger, the large current is fast, the small current is slow; Fourth, depending on whether your battery has any surplus, if there is no electricity at all, the charging time will be longer, and if there is still surplus power, the charging time will be shorter. The charge of a nickel-metal hydride battery has a formula: the battery's capacity(mA) and the charging current(mA) × 1.2 ~ 1.5 = the time(hour) required for the battery to be full. Due to different chargers, the size of the charging current is also different. The charging time is generally marked on the charger's instructions. It is filled with four 2300mAh batteries. The standard charge takes 10 to 20 hours, the fast charge takes 6 to 8 hours, and the rapid charge takes 1 to 2 hours.

The better chargers now have automatic detection. The battery stops charging automatically after filling. When the battery is charging, the battery is warm. After the charging is over, the battery will stop for a while. Full instructions are different according to the charger, and some are flashing lights when charging, full of often bright; Some are charging the indicator light Changliang, full of rear indicator light extinguished; Some are red(or green) when charging, and green(or red) when full.
