Car Battery Charging Time

Car battery charging time (hours) = factor of rechargeable battery capacity (mAh)/charging current (mA)*1.5 If you use a 1600mAh rechargeable battery and the charger charges with 400mA, the charging time is: 1600/400*1.5= 6 hours (note: this method is not applicable to newly purchased or long-term unused rechargeable batteries) NiMH rechargeable batteries and lithium-ion rechargeable batteries actually have a memory effect. Are they really not discharged when used? In fact, the memory effect of Ni-MH rechargeable batteries and Li-ion rechargeable batteries is very slight, and it is not worth paying attention to it. (Please note that when you see this, do not use the discharge function of the car battery charger to discharge the nickel-metal hydride rechargeable battery and lithium-ion rechargeable battery, especially the lithium-ion rechargeable battery.

Due to its own material factor, the battery itself is not allowed Can withstand the forced discharge of the charger. If you insist on discharging the lithium-ion rechargeable battery, it will eventually cause damage to the battery.) In addition, if you use a nickel-cadmium rechargeable battery that needs to be discharged, it is recommended that you use the battery no matter how often it is used. It is best to charge and discharge the rechargeable nickel-cadmium battery every two or three months, so as to ensure that the memory effect of the rechargeable nickel-cadmium battery has a minimum impact on the battery.
