How long does it take for the battery to be fully charged?

Presumably most car owners know that when their car battery is dead, they need to charge the battery in time, but the charging method of the battery will change as time goes by. For example, when the battery was out of power, it was always charged at high power, but once the battery was fully charged, the charging method of the battery would be changed from high-power charging to small-scale current charging.

And this charging method is the time we often say to float the battery. Although in this case, the charger shows that the battery is fully charged, but in fact there is still room in the battery to recharge a part of the battery. At this time, charging the battery with a small current is floating charging, and The floating charging time basically needs to be about 30-60 minutes, and if it is a car battery, it may be properly extended to more than 60 minutes.

Especially the floating charging method can better maintain the battery. Therefore, car owners can completely float charge the battery with confidence, but the time of floating charge must be well controlled. The best way to judge is when the light of the charger turns green, or the voltage displayed on the voltage regulator. has declined.

When the current can be stabilized in a range, it is already in the stage of floating charge, and then it can be timed. Therefore, when the battery is fully charged, it is best to float charge for 30 to 60 minutes, so that the power in the battery can reach the highest or even fullest state.
