How long does it take to charge a Ni-MH battery?

The newly purchased nickel-hydrogen battery, in order to ensure the recycling of the battery, the first charging time is slightly longer. When using, in principle, it should be full and used up. Generally speaking, although the memory effect of nickel-hydrogen rechargeable batteries is much smaller than that of nickel-cadmium rechargeable batteries, if used improperly, the capacity will still be reduced. So when in use, try to charge as much as possible after the battery is discharged. Generally, it is necessary to charge three times first, each time about 12 hours. How long does it take for Ni-MH batteries to be fully charged? On the market, rechargeable batteries, including Nanfu, are generally made of Ni-MH. Ni-MH rechargeable batteries generally take more than ten or twenty hours to charge, the fastest fast charge. It will take 8 to 9 hours, and because of the memory effect of the Ni-MH battery, it is generally necessary to drain the battery and recharge it until it is fully charged, otherwise it will affect the battery life. First, it depends on the nominal capacity of your battery. The larger the capacity, the longer the charging time is. The second is to see how many batteries you charge at the same time. The charging time for two batteries and four batteries is different. Charge two batteries. It is twice as fast as charging four cells; third, it depends on the amount of current that your charger can output, the higher the current, the faster, the lower the current, the slow; the fourth is to see if your battery is left, if it is completely empty, The charging time is longer, and if there is remaining power, the charging time is shorter. There is a formula for charging Ni-MH batteries: battery capacity (milliamp hours) u0026 pide; charging current (milliamps) u0026 TImes; 1.2~1.5 u003d the time required for the battery to be fully charged (hours). Due to different chargers, the magnitude of the charging current is also different. The charging time is generally indicated on the charger manual. It takes 10 to 20 hours for standard charging, 6 to 8 hours for fast charging, and 1 to 2 hours for fast charging. The normal charging time is mainly related to the charging current of the charger used, and the general Ni-MH battery charger can automatically stop when it is fully charged. For example, the battery used can be fully charged in one hour with a 1000mA charger. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
