The correct charging method of Ni-MH battery

by:dcfpower     2021-02-26
When you are using Ni-MH batteries, don’t wait until the batteries are dead. It’s correct to charge the battery after the device’s battery is fully discharged, but this is for newly purchased Ni-MH batteries. It is best to charge the battery overnight before using it. Fast charging cannot be started when the battery temperature is too low. Since most of the rechargeable batteries used in the past are Ni-MH batteries, when the battery temperature rises to the specified value, fast charging is used at the beginning and must be stopped immediately fast charging. Ni-MH batteries have a memory effect. If they are not fully discharged and recharged, their life will be shortened. If they are not used for a long time or when a new battery is charged, it will also affect the life of the battery. This method called initialization can guarantee The battery reaches the maximum capacity. The first charge of the Ni-MH battery takes more than ten hours, and the battery power is quickly restored.u003cpu003eu003c/pu003e Fast charging is charging with high current. The fast charging rate is generally above 1C, and the lithium battery pack has no memory The fast charging time is determined by the battery capacity and charging rate. When the lithium battery pack is charged for the first time, the indicator light turns green and can be charged for another 1-2 hours. When it is used up, the chemical substance will not react and the life will be reduced. However, most mobile phones and general products now use lithium batteries. If you want to keep the battery long, the best way is to charge it when nothing happens. As long as the battery is connected to the charger and the charger is connected to the power supply, in the maintenance charging state, In order to ensure that the battery is fully charged but cannot be charged, multiple methods can be used: timing control, voltage control and temperature control. The charger will replenish the battery at a certain charging rate to keep it in the best full state anytime and anywhere. The battery is always fully charged. Regardless of the charging method, the premise must be a corresponding charger. Generally speaking, Ni-MH batteries are industrial batteries. The charger needs to design the charger circuit according to the specific voltage and current parameters of the battery. If you choose a charger with a higher voltage, the Ni-MH battery will be damaged. If the output voltage of the charger is lower, the Ni-MH battery will not reach full capacity.u003c/pu003e
