Vehicle battery charging time

Charging time (hours)=the coefficient of charging battery capacity (mAh)/charging current (mA) * 1.5 If you use a 1600mAh charging battery and the charger uses a 400mA current to charge, 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 also have memory effect. Do you really need to discharge when you use them? In fact, the memory effect of NiMH rechargeable battery and lithium-ion rechargeable battery is very slight, which is not worth our attention. (Please note that when you see here, you should not use the discharge function of the charger to discharge the NiMH rechargeable battery and the Li-ion rechargeable battery. Especially the Li-ion rechargeable battery, because of its material factor, it is not allowed to bear the forced discharge of the charger. If you insist on discharging the Li-ion rechargeable battery, it will eventually lead to battery damage.) In addition, you use the NiCd rechargeable battery to be discharged, It is recommended that you charge and discharge the nickel-cadmium rechargeable battery every two or three months, regardless of the frequency of use of the battery. This can ensure that the memory effect of the nickel-cadmium rechargeable battery on the battery is minimized.
