What is the maximum charging current for a car battery?
1 Answers
The charging current for a car battery is related to its capacity, and a current of 6A can be used for charging. Charging time for the battery: If the battery is completely drained, it typically takes about 8 to 10 hours to charge. If a lower current is used for charging, it may take around 12 hours to fully charge. However, it's important to note that it's best not to wait until the battery is completely dead before charging. It is recommended to charge when the battery still has about 70% of its capacity remaining, in which case it only takes 6 to 8 hours to fully charge. If the battery voltage is too low, the car may have difficulty starting or may not start at all. Conversely, if the battery voltage is excessively high, it may damage the battery. Regularly check the battery voltage. If the voltage is below 11.8V, it indicates insufficient voltage, and you should turn off electrical devices and start the car to charge the battery. If the voltage drops below 10.8V, it means the battery is severely depleted, and a battery charger should be used for charging.
