Does the new rechargeable battery need to be charged for 8-12 hours?

Does the new rechargeable battery need to be charged in 8-12 hours? Any battery has self-discharge characteristics, so when the new rechargeable battery is delivered to you, the rechargeable battery may have been self-discharged for a while. This is a chemical substance inside the rechargeable battery. It has not been used for a period of time and has a passivated state, which cannot fully develop the chemical reaction and supply sufficient voltage. In this case, when using the rechargeable battery for the first time, be sure to charge the battery to restore the voltage to its original level. In fact, if your rechargeable battery has not been used for a long time, this passivation phenomenon will also occur, and it is more serious. It is better to charge and discharge the rechargeable battery 3 times to facilitate the activation of the rechargeable battery. Let the chemical substance in the rechargeable battery make full use of its use (nickel-cadmium battery). Sometimes, after a newly purchased rechargeable battery is put in the charger, it will stop charging before it is fully charged. When you encounter this problem, you only need to remove the rechargeable battery from the charger and put it in the charger to continue charging. This is normal for new rechargeable batteries, not bad rechargeable batteries (Ni-MH batteries, Li-ion batteries). Generally speaking, the charging time should not be too long, and up to 12 hours is sufficient. Once overcharged, the rechargeable battery will be damaged. How to calculate the charging time? Charging time (hours) u003d rechargeable battery capacity factor (mAh)/charging current (mA)*1.5 If a 1600mAh rechargeable battery is used, the charging current is 400mA, and the charging time is: 600/400*1.5u003d6 hours ( Note: This method is not suitable for newly purchased or long-term unused rechargeable batteries). Ni-MH rechargeable batteries and Li-ion rechargeable batteries are actually memory effects. Does it really not discharge when used? In fact, the memory effect of Ni-MH rechargeable batteries and Li-ion rechargeable batteries is very weak and not worthy of attention. (Please note that when you see this, do not use the discharge function of the charger to discharge Ni-MH rechargeable batteries and lithium-ion rechargeable batteries, especially lithium-ion rechargeable batteries. Due to its material factors, the battery itself is not allowed to withstand charging The forced discharge of the device. If you try to discharge a rechargeable lithium-ion battery, it will eventually damage the battery. In addition, if you use a nickel-cadmium rechargeable battery, to discharge it, it is recommended that you charge and discharge the nickel-cadmium rechargeable battery every two or three months Regardless of the frequency of battery use, to ensure that the battery is a nickel-cadmium rechargeable battery, the memory effect of the battery is minimized.
