How to charge the car battery

Hello, landlord! Car batteries for cars don't need you to charge them specially. When the car is running, the charger will charge the car battery. If the voltage is lower than12.45v, take out the battery. If you need to charge, you need a constant voltage current-limiting charger first. Connect the positive terminal of the charger with the positive terminal and the negative terminal with the negative terminal. At the initial stage of charging, the current is large (as a limited value) and the voltage keeps rising; After charging for a period of time, the charging voltage reaches a constant value, and the corresponding current value also begins to appear inflection point, and gradually decreases from the limit value; In the final stage of charging, the charging voltage remains unchanged and the charging current is reduced to about1a.

The length of charging time mainly depends on the degree of battery loss.

It is mainly used for conventional charging of storage batteries and after-sales batteries.
